Technical field

The present invention relates to a kind of manufacturing methods that the coreless rolls to be formed is rolled under the premise of not having the core materials such as ground paper.

Background technique

For example, in the case where thin paper wood (paper) as toilet roll is rolled up web-like, preparation ground paper etc. It is shaped generally as the core material of tubular, paper winding is manufactured in the core material.In addition, the case where having used up toilet roll Under, remaining core material becomes rubbish, so there is the coreless roll of hygiene paper etc. formed under the premise of without using core material.

For example, when manufacturing coreless roll of hygiene paper, blow weak bonding agent of bonding force etc. to the winding start end of paper and Paper is wound in around axis, successively paper is wound and is formed as web-like (referring for example to patent document 1).Specifically, manufacturing When coreless roll of hygiene paper, the front end of paper is wound in around rod (Japanese: batching り シ ャ Off ト), further in progress and front end In a period of the winding for 5,6 weeks amounts that portion is connected, bonding agent etc. is blowed to the part and is bonded in a manner of becoming tubular. In addition, for example when winding paper as described above, it is dry to implementing to heat and make blowed bonding agent etc. around axis.

In addition, there is a kind of coreless roll of hygiene paper manufacturing device, which is winding paper to spool Zhang Shi is provided with confession in the axle portion of the application roll (Japanese: ラ イ テ ィ Application グ ロ ー Le) for rolling periphery side contacts with the paper The hole portion of adhering liquid exudation (referring for example to patent document 2).

The device starts in process in the winding of paper, and adhering liquid is attracted in the axle portion of application roll, seeps adhering liquid The axle portion surface is arrived out coated on the paper being sandwiched between application roll and spool, which is rolls-up on spool and is manufactured At web-like.Specifically, application roll is embedded with outside the axle portion for being provided with hole portion as described above becomes thick cyclinder for spongiform The roller portion obtained after shape.It is formed with small capillary between the inner wall part and outside wall portions of roller portion, is exuded to the surface of axle portion Adhering liquid via capillary reach roller portion surface.The adhering liquid for being exuded to roller portion surface is applied to be clipped by spool and application roll Paper, the center of toilet roll is fixed.

Summary of the invention

Subject to be solved by the invention

Previous coreless rolls due to manufacturing as described above, so the winding start of paper is partially cured and becomes cylinder Shape.Therefore, it when roll paper is when using up period and closing on, such as is difficult to the keeping body of the self-sustaining roll paper and pulls out, even without core The roll paper of material can not also use up whole, there are problems that the part residual having cured at volume center.

The present invention is made into view of above-mentioned project, and it is an object of the present invention to provide a kind of can will wind up makes for the paper of web-like With the manufacturing method of the coreless rolls to least significant end.

Solution for solving the problem

Coreless rolls manufacturing method of the invention is characterised by comprising: the 1st process, and the 1st process rolls paper And be formed as the roll paper of web-like；2nd process, the 2nd process will spray the insertion section of bonding agent to the centre bore of the roll paper Insertion；3rd process, the 3rd process adhere to the bonding agent to the specified position of the centre bore；And

4th process, the 4th process are thermally dried the position for being attached with the bonding agent and make the centre bore Both ends solidification, the 3rd process is attached to the bonding agent near the extension both ends of the centre bore, the bonding agent tool There is the bonding force for the degree that can make to roll the paper removing for the web-like when using the roll paper, the 4th process is attached Keep the bonding agent dry from before the diffusion of the specified position of the centre bore in the bonding agent of the centre bore.

In addition, coreless rolls manufacturing method of the invention is characterized in that, the 2nd process makes the insertion section described in Two end side of extension of centre bore is inserted into and makes the borehole enlargement prescribed level of the both ends part of the centre bore towards center side, 3rd process makes the bonding agent be attached to the part that the aperture of the centre bore has been extended.

In addition, coreless rolls manufacturing method of the invention is characterized in that, extension of the 3rd process from the centre bore Two end sides reduce the adhesion amount of the bonding agent towards center side, and the 4th process is thermally dried so that the center The both ends in hole farthest solidify.

Invention effect

, will not be easily out of shape under packed state when shipment conveying using the present invention, it can when in use not Roll paper is used up on the ground such as residual core material.
