Technical Field
The present invention relates to a slide fastener and a method of manufacturing the slide fastener, and particularly to a slide fastener and a method of manufacturing the slide fastener.
Background
The zipper is a daily article commonly used in life and is mainly installed on clothes, bags and the like. The slide fastener is roughly divided into a closed slide fastener and an open slide fastener as required. The closed zipper is provided with an upper stopper and a lower stopper at both ends of the zipper, a zipper head slides between the upper stopper and the lower stopper, and one end of the lower stopper cannot be separated, so that the whole zipper cannot be separated into 2 zipper tooth belts. In the open slide fastener, a stopper is provided at one end, and an opening/closing tool for fully opening the slide fastener is provided at the other end. The shutter mainly has a case body of a fastener tape provided on one side of 2 fastener tapes which can be engaged with each other, a case bar protruding from the case body, and an insert bar of the fastener tape provided on the other side. When the open zipper is operated, the box rod and the zipper cloth belts on the two sides of the insert rod are mainly held, and the insert rod is inserted into or pulled out of the box body.
For example,
However, since the covered region of the fastener tape to which the film is attached becomes hard, there is a possibility that a hand may hit an end portion of the film to cause a sense of discomfort when the above-described insertion or extraction of the insert pin into or from the case is performed. Further, after the zipper is sewn to the garment, the end portion of the film may come into contact with the skin of the wearer, causing an uncomfortable feeling.
In addition, in

providing a film having a predetermined size at a predetermined position of the pair of fastener element tapes from which a part of the fastener elements is removed;
opening holes are formed in the parts, provided with the films, of the pair of zipper tooth belts and the parts, not provided with the films, of the pair of zipper tooth belts;
an opening and closing means for engaging and disengaging respective ends of the pair of fastener tapes is formed corresponding to a position of the opening hole;
after the opening/closing tool is formed, the fastener tape is cut by a cutter blade at a predetermined distance from the end edge of the film in the longitudinal direction to obtain a single fastener.
Preferably, the cutting knife cuts only the fastener tape without cutting the film when the cutting knife cuts.

According to the slide fastener of the present invention, since the pair of fastener tapes are provided with the films on both sides of the shutter and protrude from the end edge of the film in the longitudinal direction at the end edge of the end where the shutter is located, the fastener tapes can shield the end portion of the film as the hardened portion, and when the insert pin is inserted into or removed from the case, the hand first touches the relatively soft fastener tape, so that the hand can be prevented from touching the end portion of the film as the hardened portion to cause discomfort, and the handling feeling can be improved. Further, even after the zipper is sewn to the garment, the end portion of the film as the hardened portion can be prevented from hitting the skin of the wearer and causing an uncomfortable feeling.
In addition, according to the method for manufacturing a slide fastener of the present invention, the amount of film used can be reduced, and thus the cost can be saved. Further, the same effects as described above can be obtained with respect to the slide fastener obtained by the manufacturing method.

Detailed Description
A slide fastener and a method of manufacturing a slide fastener according to an embodiment of the present invention will be described with reference to fig. 1 to 4. The drawings are schematic, and it should be noted that the scale of each dimension and the like are different from those of the actual drawings. Therefore, specific dimensions and the like should be determined with reference to the following description. In addition, the drawings may include portions having different dimensional relationships and ratios from each other.
In the description of the present invention, the terms defined below may be referred to. The front-rear direction is a direction that coincides with the longitudinal direction of the slide fastener or the fastener tape and/or the moving direction of the slider, wherein the moving direction when the slide fastener is pulled is front and the moving direction when the slide fastener is pulled is rear. The left-right direction is a direction that coincides with the width direction of the slide fastener or the fastener tape (the arrangement direction of the fastener tapes), and/or a direction orthogonal to the front-rear direction. The vertical direction is a direction orthogonal to both the front-back direction and the left-right direction, and/or a direction corresponding to the thickness direction of the fastener tape. Further, the end of the slide fastener is one end in the longitudinal direction of the slide fastener.
First, the entire structure of the slide fastener according to the embodiment of the present invention will be described.

Fig. 3 (a) to (c) are views for explaining the positional relationship between the dicing blade and the end of the film. Fig. 3 (a) shows a state in which the cutting blade is flush with the end of the film and the inclined surface of the cutting blade does not face the film, fig. 3 (b) shows a state in which the cutting blade is spaced apart from the end of the film and the inclined surface of the cutting blade does not face the film, and fig. 3 (c) shows a state in which the cutting blade is spaced apart from the end of the film and the inclined surface of the cutting blade faces the film. As described above, by providing the cutter blade in the state shown in fig. 3 (c) and cutting the fastener tape, the defect rate can be reduced, and even if the cutting position of the cutter blade is shifted, the protruding dimension of the fastener tape can be left on the single fastener obtained by cutting. In addition, although the cutting blade shown in fig. 3 has an inclined surface on one side, the cutting blade may have inclined surfaces on both sides. For a cutting blade having inclined surfaces on both sides, it is possible to have the inclined surfaces on either side facing the film.
