Technical Field

The present invention relates to an additive applying device for supplying and applying an additive from the outside of a binding machine to a spine portion of a paste-coated signature in a vertical form at an additive applying position stopped in the binding machine, and a binding system provided with the device.

Background

A perfect binding machine with a cold yarn backing supply device is known in the art (for example, refer to patent document 1). The perfect binding machine comprises a clamping device which clamps the book in a standing state and can move along a specified path; a series of processing units (a milling unit, an overlap width unit and an upper cover unit) arranged along the path and performing perfect binding processing; and a signature feeding unit that feeds the signatures to the nip device at a signature feeding position on an upstream side than the series of processing units on the path.

The upper cover unit has a top press plate and a pair of holding plates disposed above the top press plate. The cover feeding unit has a cover carrier on which the cover is placed, a knock-up plate that delivers the cover from the cover carrier to the upper cover unit, and a cover delivery mechanism on the pair of clamp plates.

When the binding process is started, the cover is delivered from the cover carriage to the top platen and the pair of clamp plates of the upper cover unit via the cover delivery mechanism. Then, the signatures held by the holding device reach predetermined positions above the knock-up plate and the pair of holding plates, and when stopping, the knock-up plate and the pair of holding plates are raised to the holding position, the cover is pressed against the spine of the signatures via the knock-up plate, and then the pair of holding plates hold both sides of the spine of the signatures, and thereby the cover is pressed against both sides of the spine of the signatures, the cover is pasted to the signatures, and the binding is completed.

Thus, according to the binding machine, the paperback binding can be realized. On the other hand, when the binding machine is used for binding a finished book (forming a finished book), a cold-yarn piping supply device is used instead of the cover supply unit.

The cold yarn mounting cloth supply device comprises a cold yarn mounting cloth forming unit for forming banded cold yarn mounting cloth according to the shape of the book label; the tape-shaped cold screening cloth is delivered from the cold screening cloth forming unit to the upper cover unit of the binding machine, and supplied to the delivery unit on the pair of holding plates of the upper cover unit in a state of being spanned over these holding plates.

The cold yarn cloth-mounting forming unit comprises a continuous sheet cold yarn cloth-mounting roll; a driving part for rotating the roll and delivering the continuous sheet cold yarn cloth to the loading platform; first and second cutters cut the continuous sheet of cold yarn piping delivered by the drive in the length and width directions.

The first cutter can move in the width direction of the continuous sheet of cold yarn piping and cut the cold yarn piping in the length direction according to the thickness of the signatures. Further, the second cutter cuts the cold yarn mounted cloth cut by the first cutter and positioned on the mounting table in the width direction in accordance with the length of the signature in the up-down direction.

The delivery unit has a suction jig that sucks the band-shaped cold yarn cloth on the table and a rail that extends from the table to the upper cover unit. The rail extends from above the mounting table to above the signatures held by the holding device and stopped above the top platen and the pair of holding plates of the top cover unit, and the suction jig is movably attached along the rail with respect to the rail.

When producing a finished book on the binding machine, first, a band-shaped cold yarn pasting cloth having a size corresponding to the book is formed on a cold yarn pasting cloth forming unit of a cold yarn pasting cloth supplying device. Next, the band-shaped cold scrim is supplied to a pair of holding plates of an upper cover unit of the perfect binding machine while crossing these holding plates via a delivery unit of a cold scrim supply device.

Then, at a section feeding position of the perfect binding machine, the section is fed to a holding device, and the holding device holding the section passes through a milling unit and an upper width unit, reaches a predetermined position above a top press plate and a pair of holding plates of an upper cover unit, and stops.

Further, the knock-up plate and the pair of grip plates are raised, the band-like cold yarn mounting cloth is pressed against the spine portion of the signature via the knock-up plate, and then the pair of grip plates grip both sides of the spine portion of the signature, and thereby the band-like cold yarn mounting cloth is pressed against both sides of the spine portion of the signature, and the band-like cold yarn mounting cloth is pasted to the spine portion of the signature.

In this way, according to the perfect binding machine with the cold yarn pasting cloth supply device, the cold yarn pasting cloth in a band shape corresponding to the size of the signatures can be formed and pasted to the spine of the signatures, so that the perfect binding of a plurality of signatures of different sizes can be quickly realized.

According to the above-described configuration, when the cold yarn piping cloth is formed in a band shape from the continuous sheet-like cold yarn piping cloth, the continuous sheet-like cold yarn piping cloth is cut in the longitudinal direction of the cold yarn piping cloth according to the thickness of the signature, and then cut in the width direction of the cold yarn piping cloth according to the length of the signature in the up-down direction.

Problems to be solved by the invention

However, since the length of the signature in the vertical direction is generally larger than the thickness thereof, if the cold yarn piping cloth is cut in a continuous sheet form by the above-described cutting method, an excessive amount of waste is generated, resulting in an endless waste of material (cold yarn piping cloth), and a production cost is increased.

Further, according to the above-described configuration, the first cutter having the rolling blade is disposed on the upstream side, the second cutter having the linear blade is disposed on the downstream side, and the cold yarn topping in the continuous sheet form is cut by the first cutter while being wound up by a predetermined length (length corresponding to the length of the spine portion of the signature), and then the winding-up operation of the cold yarn topping is suspended and cut by the second cutter.

Incidentally, in the case of changing the size of the signature, the length of the continuous sheet-like cold-yarn piping cloth to be wound needs to be changed in accordance with the change in the length of the signature in the vertical direction, and the position of the rolling blade of the first cutter needs to be changed in the width direction of the continuous sheet-like cold-yarn piping cloth in accordance with the change in the thickness of the signature.

However, in this case, since the first cutter performs cutting during winding out of the continuous sheet-like cold yarn piping, if the position of the blade edge of the first cutter is changed during the operation of the apparatus, the wound-out cold yarn piping is cut off during the change of the position, resulting in endless waste. Therefore, before the position change of the rolling blade of the first cutter is completed, the unwinding of the continuous sheet-like cold yarn piping must be stopped.

According to the aforementioned structure, there is a problem that the cold yarn laminating feeding device needs to be stopped and the position of the rolling blade of the first cutter needs to be set every time the size of the signature is changed, and the cold yarn laminating feeding device can be restarted after the position setting is completed, which causes a reduction in production efficiency.

Accordingly, an object of the present invention is to provide an additional material application device capable of controlling the endless waste of materials and supplying and applying additional materials such as cold yarn backings, and a binding system having the same.

Still another object of the present invention is to provide an additional material attaching apparatus capable of changing the size of a signature without stopping the additional material attaching apparatus and supplying and attaching an additional material such as a cold yarn mounting cloth, and a binding system having the same.

Detailed Description

The structure of the present invention will be described according to a preferred embodiment with reference to the accompanying drawings. Fig. 1 is a schematic side view of the internal structure of an add-on material application device for supplying and applying an add-on material to the spine of a signature according to an embodiment of the present invention.

Fig. 1 shows a binding system with a binding machine M and an add-on material application device 1, wherein the add-on material application device 1 is connected to the binding machine M. In addition, for the sake of clarity, only the adsorption head of the delivery unit is depicted in fig. 1, representing the delivery unit (the structure thereof will be described in detail later).

An additional material applying apparatus 1 including a roll accommodating unit 3 rotatably accommodating a roll 2 of a continuous sheet-like additional material Q about a horizontal axis in a housing 52 thereof; the continuous sheet-like additional material Q is wound out from the roll containing unit 3 to the unwinding unit 5 of the cutting station 4. The control unit 50 controls the operation of the unwinding unit 5.

Here, the "additional material" refers to a sheet material that is stuck to the spine portion of the signature in the finishing process, and includes, for example, cold yarn paperhanging and paper.

The unwinding unit 5 is constituted by a pair of unwinding rollers 5a, 5b rotatable about horizontal axes, respectively. Further, a guide roller 6a and a pair of guide rollers 6b, 6c are disposed between the pair of unwinding rollers 5a, 5b and the roll accommodating unit 3, and are rotatable about horizontal axes, respectively. Further, a driving force may be applied to the pair of guide rollers 6b and 6c so that a reverse torque is applied in a direction opposite to the feeding direction of the pair of unwinding rollers 5a and 5 b. Thereby, tension can be applied to the additional material Q. When the additional material Q is unwound, the pair of guide rollers 6b and 6c transport the additional material Q in the feeding direction by friction while applying a reverse rotation torque. However, when the unwinding of the additional material Q is stopped, the counter torque of the pair of guide rollers 6b and 6c is also stopped.

The continuous sheet-like additional material Q unwound from the reel 2 is guided between the pair of unwinding rollers 5a and 5b via a part of the circumferential surface of the guide roller 6a and between the pair of guide rollers 6b and 6 c. Then, each time the pair of unwinding rollers 5a and 5b is rotated in accordance with a command from the control section 50, the continuous sheet-like additional material Q of a predetermined length is wound out from the roll 2 to the cutting station 4. The cutting station 4 is provided within the housing 52.

Further, a curl corrector 7 for correcting the curl of the continuous sheet-like additional material Q is disposed between the pair of guide rollers 6b and 6c and the pair of unwinding rollers 5a and 5 b.

The add-on material attaching device 1 further includes a cutting unit 8 disposed at the cutting station 4, cutting the continuous sheet-like add-on material Q wound out by the unwinding unit 5 in accordance with the size of the signature B, and forming a band-like add-on material S.

The sleeve 21 has a regular hexagonal insertion hole corresponding to the cross section of the drive shaft 16 of the downstream side conveyor 13 extending along the center axis, and the drive shaft 16 of the downstream side conveyor 13 extends through the insertion hole of the sleeve 21.

The second cutter 11 further has a pair of rolling blades 22a and 22b arranged between the pair of side walls of the tool holder 19 and facing each other in the vertical direction while holding the delivery path therebetween. The respective rolling blades 22a, 22b are held between the pair of feed rollers 23a, 23 b; 24a, 24b, and a pair of feed rollers 23a, 23 b; 24a, 24 b.

The tool post drive mechanism 20 has a ball screw 26 extending in parallel along the upper slide rail 18a and disposed in a fixed position so as to be rotatable around an axis; a ball screw nut 27 provided on the tool holder 19 and fitted with the ball screw 26; and a ball screw drive mechanism 28 that rotates the ball screw 26.

The ball screw drive mechanism 28 has a pulley 28a fixed to an end of the ball screw 26 on the side of the fixed belt 14; a motor 28b disposed below the pulley 28a and having a drive shaft parallel to the ball screw 26; a pulley 28c fixed to a drive shaft of the motor 28 b; and an endless transmission belt 28d trained between the pulleys 28a and 28 c.

In this way, by rotating the drive shaft 16 by the drive mechanism 17 (motor 17b), the pair of rolling blades 22a and 22b of the second cutter 11 are also rotated while rotating the downstream side conveyor 13 (fixed and movable conveyors 14 and 15). Further, by rotating the ball screw 26 of the tool rest driving mechanism 20 forward and backward by the ball screw driving mechanism 28 (motor 28b), the tool rest 19 (the pair of rolling blades 22a and 22b) and the movable conveyor belt of the downstream side conveyor belt 13 can be moved in the direction crossing the unwinding direction (arrow X).

The additional material piece attaching device 1 is also provided with a gripping device 30 which can support the lower part of the strip-shaped additional material piece S and can simultaneously clamp the strip-shaped additional material piece S; a first gripper driving mechanism 31 for moving the gripper 30 between a retracted position (see fig. 1 and 4a) inside the housing 52 and an advanced position (see fig. 4B) outside the housing 52; and a second gripper driving mechanism 32 for moving the gripper 30 between the advanced position and a raised position (see fig. 5a) above the advanced position. The control unit 50 controls the operations of the first gripper driving mechanism 31 and the second gripper driving mechanism 32.

The gripper 30, the first and second gripper driving mechanisms 31 and 32, and the cutting unit 8 are arranged in two upper and lower stages with the cutting unit 8 arranged above. The hand grip 30 is disposed within the housing 52 when in the retracted position and extends outside of the housing 52 when in the advanced position. The first gripper driving mechanism 31, a main portion of which is disposed inside the housing 52, has a front portion thereof protruding outside the housing 52 when in the advanced position. The second gripper drive mechanism 32 is disposed adjacent an exterior of the housing 52. Therefore, as shown in fig. 1, when the additional material attaching device 1 is attached to the binding machine M, the second gripper driving mechanism 32 is located inside the binding machine M. However, the second gripper driving mechanism 32 may be provided in the housing 52.

Fig. 3 is a top view of the gripper 30 of the add-on material application device of fig. 1, and the first and second gripper driving mechanisms 31, 32. Fig. 4 and 5 are cross-sectional views taken along the line Y-Y in fig. 3 for explaining the operation of the gripper 30 and the first and second gripper driving mechanisms 31 and 32 in fig. 3.

The gripper device 30 includes a holding portion 30g that holds the additional material S in a belt shape. The clamping portions 30g can increase or decrease the distance between the placing surfaces of the gripper 30 on which the strip-shaped additional material S is placed, and the additional material S can be temporarily fixed by clamping the additional material S between the placing surfaces. The control unit 50 controls the operation of the clamping unit 30 g.

Referring to fig. 3 to 5B, the first gripper driving mechanism 31 has at least one (two in the present embodiment) slide rail 33 extending obliquely downward outward from the inside of the housing 52; a slider 34 mounted on the slide rail 33; a flat plate-shaped arm 35 extending in parallel along the slide rail 33, attached to the upper surface of the slider 34, swingable with a rear end edge portion 35b as a support shaft, and having the gripper 30 attached to a front end 35 a; and a slider driving mechanism 36 for moving the slider 34 between a retracted position where the gripper 30 is disposed at the retracted position and a projected position where the gripper 30 is disposed at the advanced position.

The slider 34 mounting arm 35 is a pair of through holes provided at regular intervals in the front-rear direction on both sides of the insertion arm 35; specifically, this is accomplished by a pair of flanged pins 37a, 37b each fixed to the slider, a compression spring 38a disposed between the flange of the front flanged pin 37a and the arm 35 among the pair of flanged pins 37a, 37b, and a compression spring 38b disposed between the flange of the rear flanged pin 37b and the arm 35 among the pair of flanged pins 37a, 37 b. The front compression spring 38a has a lower spring constant than the rear compression spring 38 b.

The slider drive mechanism 36 includes a ball screw 39 extending in parallel along the slide rail 33 and disposed to be rotatable around an axis at a fixed position; a ball screw nut 40 provided on the slider 34 and fitted with the ball screw 39; and a ball screw drive mechanism 41 for rotating the ball screw 39 about the axis.

The ball screw drive mechanism 41 is composed of a pulley 41a fixed to the rear end of the ball screw 37, a motor 41b having a drive shaft parallel to the ball screw 39 below the pulley 41a, a pulley 41c fixed to the drive shaft of the motor 41b, and an endless belt 41d looped between the pulley 41a and the pulley 41 c.

Then, the ball screw 39 is rotated in the forward and reverse directions by the ball screw drive mechanism 41 (motor 41b), and the slider 34 slides along the slide rail 33.

The second gripper driving mechanism 32 is constituted by an arm driving mechanism 42 that is capable of swinging the arm 35 about the rear end edge portion 35b (support shaft) of the arm 35 between a horizontal position and an inclined position inclined downward (extending in parallel along the slide rail 33) from the horizontal position.

The arm driving mechanism 42 is constituted by a cylinder 43 disposed on the lower side of the arm 35 in front of the projecting position of the slider 34 and extending in the vertical direction, a horizontal support shaft 43b is attached to the front end of a piston rod 43a of the cylinder 43 and extends in the direction crossing the delivery path, and a roller 43c is attached to both ends of the support shaft 43b so as to be rotatable about the support shaft 43 b.

Then, the piston rod 43a of the cylinder 43 reciprocates between a first position where the roller 43c is retracted below the inclined position of the arm 35 and a second position where the roller 43c protrudes upward from the inclined position of the arm 35.

In this way, the piston rod 43a of the cylinder 43 is always in the first position, and when the slider 34 occupies the projecting position, the piston rod 43a moves from the first position to the second position, whereby the arm 35 swings from the inclined position to the horizontal position. Then, the piston rod 43a returns from the second position to the first position, whereby the arm 35 swings from the horizontal position to the inclined position.

The additional material application device 1 also has a delivery unit 44 that delivers the additional material S in the form of a strip from the cutting station 4(a stop position downstream of the delivery path of the delivery mechanism 10) to the gripper 30 located in the retracted position. The control unit 50 controls the operation of the delivery unit 44.

Fig. 6 is a front view of the delivery unit (view viewed in the arrow X direction of fig. 1).

As shown in fig. 6, the delivery unit 44 has an adsorption head 45 capable of adsorbing the strip-shaped additional material S and an adsorption head driving mechanism 46 that moves the adsorption head 45 between the cutting station 4 (the stop position of the strip-shaped additional material S) and the retracted position of the gripper 30.

The suction head 45 includes a plurality of suction cups 45a and a negative pressure generating unit 45b for generating suction force for each suction cup 45 a.

The suction head driving mechanism 46 has a first slide rail 46a extending in the horizontal direction along the slide rail 33 of the first gripper driving mechanism 31; a first slider 46b mounted on the first slide rail 46 a; a first ball screw 46c extending in parallel along the first slide rail 46a and arranged to be rotatable around an axis at a fixed position; a first ball screw nut 46d mounted on the first slider 46b and fitted with the first ball screw 46 c; and a first rotation driving mechanism 46e that rotates the first ball screw shaft 46 c.

The suction head driving mechanism 46 further has a second slide rail 46f attached to the first slider 46b and extending in the up-down direction; a second slider 46g mounted on the second slide rail 46 f; a second ball screw 46h mounted on the first slider 46b, extending in parallel along the second slide rail 46f, and rotatable around an axis at a fixed position; a second ball screw nut 46i mounted on the second slider 46g and fitted with the second ball screw 46 h; and a second rotation driving mechanism 46j attached to the first slider 46b and rotating the second ball screw 46 h.

The suction head driving mechanism 46 further has a third slide rail 46k mounted on the second slider 46g, extending in the horizontal direction and at right angles to the first slide rail 46 a; a third slider 46m mounted on the third slide rail 46 k; a motor 46n mounted on the second slider 46g, with a drive shaft (not shown) extending in parallel along the first slide rail 46 a; a pulley 46p mounted on the second slider 46g and rotatable about an axis parallel to the drive axis of the motor 46 n; and an endless belt 46q which is hooked between a pulley (not shown) attached to a drive shaft of the motor 46n and the pulley 46p and fixes the third slider 46 m.

Then, the suction head 45 is mounted on the third slider 46m in a straight line along the third slide rail 46k with the suction cups 45a facing downward, respectively.

In this way, the first ball screw shaft 46c is rotated in the forward and reverse directions by the first rotary drive mechanism 46e, and the suction head 45 is moved in a direction in which the cutting station 4 (the stop position of the band-shaped additional material S) or the gripper 30 located at the retracted position approaches or separates from each other, and the second ball screw shaft 46h is rotated in the forward and reverse directions by the second rotary drive mechanism 46j, and the suction head 45 is moved up and down, and the endless belt 46q is rotated in the forward and reverse directions by the motor 46n, and the suction head 45 is moved in the longitudinal direction of the band-shaped additional material S.

The control unit 50 is composed of, for example, a cpu (central Processing unit), a ram (random Access memory), a rom (read Only memory), and a computer-readable storage medium. Further, a series of processes for realizing the respective functions are stored in a storage medium or the like in the form of a program, for example, and the CPU reads out the program into a RAM or the like and executes processing and arithmetic processing of information, thereby realizing the respective functions. In addition, the program may be applied to a system preinstalled in a ROM or other storage medium, a system provided in a state stored in a computer-readable storage medium, a system distributed by a wired or wireless communication unit, or the like. The computer-readable storage medium includes a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, and the like.

Next, the action of the additional material attaching device 1 will be described.

Referring again to fig. 1, the additional material application device 1 is attached to the binding machine M in an arrangement posture in which the advancing position of the gripper 30 is located directly below the spine of the signature B stopped at the additional material application position P in the binding machine M, and the gripper 30 brings the strip-shaped additional material S into press contact with the spine of the signature B at the rising position.

Further, the position of the stopper 29 of the cutting unit 8 is adjusted in advance so that the band-shaped additional material S stopped by the stopper 29 is arranged substantially parallel to the spine portion of the signature B stopped at the additional material applying position P of the stapler M.

In the present embodiment, the binding machine M is configured as a perfect binding machine, the additional material attaching position P is configured as an upper cover position of the perfect binding machine (a position directly above the top plate F1 and the pair of holding plates F2 and F3 of the upper cover unit F), and the holding device K holding the signature B in an upright state stops at the position.

Before the operation of the add-on material attaching device 1, the size (the length and the thickness in the vertical direction) of the signature B is inputted to the control section 50 of the add-on material attaching device 1 through a control panel (not shown), the initial setting of the add-on material attaching device 1 is performed based on the input value, and then the operation of the add-on material attaching device 1 is started.

Then, the unwinding unit 5 winds out the continuous sheet-like additional material Q having a length corresponding only to the thickness of the signature B to the cutting station 4 (on the conveying surface of the upstream-side conveyor belt 12), and stops there. Next, the linear blade 9a of the first cutter 9 is lowered from the standby position to the cutting position, and then raised from the cutting position to the standby position. Thereby, the continuous sheet-like additional material Q is cut in its width direction.

The cut additional material R is delivered from the first cutter 9 to the second cutter 11 and the downstream-side conveyor 13 by the upstream-side conveyor 12, and then introduced into feed rollers 23a, 24a opposed to the second cutter 11 up and down while being delivered by the downstream-side conveyor 13; 23b, 24b and a pair of rolling blades 22a, 22b which are opposite up and down. Thereby, the additional material R cut by the first cutter 9 is cut into a long strip-like additional material S having a length corresponding to the vertical direction of the signature B.

The tape-shaped additional material S is delivered to the downstream side of the second cutter 11 and stops on the delivery path abutting against the stopper 29.

Then, the additional material S in a belt shape is delivered from the cutting station 4 (the downstream end of the delivery path of the delivery mechanism 10) to the gripper 30 located at the retracted position via the suction head 45 (delivery unit), and is delivered to the gripper 30 (refer to fig. 4A).

Next, with the arm 35 maintained in the inclined position, the slider 34 slides toward the stapler M, and the gripper 30 occupies the advanced position while gripping the additional material S in the form of a strip. At this time, the strip-shaped additional material S (gripper 30) is located just below the ridge portion to which the paste is applied of the signature B stopped at the additional material application position P.

Subsequently, the arm 35 swings from the inclined position to the horizontal position, and thereby the gripper 30 moves from the advanced position to the raised position (see fig. 5A). In this way, the band-shaped additional material piece S is stuck to the spine of the signature B. Then, after the gripper 30 releases the additional material S in a band shape (see fig. 5B), the arm 35 swings from the horizontal position to the inclined position, and the attachment of the additional material is completed.

Thereafter, the slider 34 is moved toward the additional material application device 1, the gripper 30 occupies the retracted position, and the next piece of the additional material S in the form of a strip is delivered to the gripper 30 by the suction head 45 (refer to fig. 4A).

According to this embodiment, provide an additional material and paste device, its characterized in that: at the entrance of the cutting station 4, a first cutter 9 is provided for cutting a continuous sheet-like additional material Q of a length corresponding to the thickness of the signature, transversely to the direction of unwinding (arrow X); a delivery mechanism 10 for delivering the cut additional material R from the first cutter 9 to a winding-out direction (arrow X) of the continuous sheet-like additional material is disposed on a downstream side of the first cutter 9; on the delivery path of the delivery mechanism 10, a second cutter 11 is arranged to cut the cut additional material R delivered on the delivery path in the unwinding direction (arrow X). The positions of the rolling blades 22a and 22B of the second cutter 11 are adjustable in a direction crossing the unwinding direction (arrow X) according to the vertical length of the signature B.

In this way, the continuous sheet-like additional material Q is cut in the direction (the width direction of the continuous sheet-like additional material Q) crossing the feeding direction (arrow X) of the continuous sheet-like additional material Q according to the thickness of the signature B, and then the cut additional material R is cut in the feeding direction (arrow X) according to the length of the signature B in the vertical direction, so that waste can be reduced to the maximum extent, and the endless waste of the material (additional material) can be suppressed.

Further, according to the present embodiment, during the operation of the additional material application device 1, the first cutter 9 intermittently performs the cutting action in synchronization with the action of the unwinding unit 5 intermittently winding out the continuous sheet-like additional material Q, and the additional material R cut by the first cutter 9 is cut by the second cutter 11 while the additional material R is delivered from the first cutter 9 by the delivery mechanism 10.

Further, if the size of the signature B is changed during the operation of the attached material attaching device 1, the size information of the newly changed signature B is synchronously transmitted from the control section 50 of the attached material attaching device 1 to the delivery mechanism 10 and the first and second cutters 9 and 11, and the amount of the continuous sheet-like attached material Q wound out by the unwinding unit 5 is changed based on the information, and then the positions of the rolling blades 22a and 22B of the second cutter 11 are changed in the direction (arrow X) crossing the winding direction of the continuous sheet-like attached material Q.

In this case, the operation of changing the positions of the rolling blades 22a and 22B of the second cutter 11 is performed during a period from the start of unwinding of the unwinding unit 5 to the arrival of the additional material R cut by the first cutter 9 at the second cutter 11, and the size of the signature B is changed while the additional material application device 1 is continuously operated.

The above description has been made of the preferred embodiments of the present invention, but the present invention is not limited to the above-described embodiments, and various modifications and changes can be made by those skilled in the art without departing from the spirit of the present invention.
