Abstract

(57) [Summary] This is an underlay paper for automatic cutting machines, which uses a breathable paper-like material to improve the efficiency of the entire work and the accuracy of the work itself. [Purpose] By using an underlayment paper made of breathable paper-like material, the process of making paper up to now, which is the process of making holes in the paper, is eliminated, and the production process is remarkably efficient. The cutting is accurate and reliable regardless of the nature of the fabric. Furthermore, the aim is to eliminate various obstacles to the machine. [Structure] This is an underlay paper which is a paper-like material having a function mainly of air permeability, which is laid under a stretched cloth when an automatic cutting machine is used.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device fixes the cloth by the vacuum method as shown in the drawing, and then lays it under the stretched cloth for use in a machine that automatically cuts using a special knife with a computer. It is about paper.

[0002]

[Prior Art]

 Conventionally, the underlay paper for using an automatic cutting machine had to pass through air to fix the fabric, so it is said that holes, such as kraft paper, will be punched out throughout the paper. , With the addition of secondary work steps.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. (B) The process of making holes in the paper itself was very difficult because it was difficult to make holes at equal intervals, and it required a great deal of skill, which caused a great problem in the productivity of the paper itself. (B) In addition, if the processed hole is not completely removed, not only is the paper waste adhering to the hole sucked into the machine and causing problems, but it also adheres to the finished product, The finish is markedly worse. (C) By making holes, the strength of the paper itself is impaired, and the paper needs to be thick to withstand the stretched fabric placed on it, not only adding cost but also the overall weight. , Strained the machine. (D) There was a difference in the ability of vacuum between the place with the hole and the place without the hole, and there was a very high possibility that a deviation in the cutting would occur when the material was cut. (E) Strictly speaking, it was necessary to change the size and spacing of the holes in order to change the vacuum capacity due to the size and hardness of the material to be cut. However, if this was difficult to do because of cost or labor problems, the machine's capacity was adjusted more easily than necessary, which placed a burden on the stable productivity of the machine.

[0004]

[Means for solving the problem]

 Use a breathable paper-like material as the underlay paper. This breathable paper-like material is represented by a non-woven fabric, etc., but of course, if it is breathable, it is basically considered to satisfy its usefulness. That is, long fibers are knitted, long fibers are melted and bonded using ultrasonic waves, and the density of paper fibers is reduced when the paper is made. Further, the paper need not be paper as long as it is tense and soft and can sufficiently support the material to be cut. Vinyl or cloth may be considered. Furthermore, it is considered that there are equivalent meanings in the case where those that do not satisfy these requirements are usefully modified by subjecting them to surface treatment.

[0005]

[Action]

 Originally, the use of a breathable material eliminates the need for a secondary processing step of drilling holes, and significantly changes the production process. Therefore, the productivity of the paper itself can be significantly improved. Furthermore, since the ability of the baume can be fully utilized and evenly applied to the cloth without considering the characteristics of the cloth, the cloth can be securely fixed. Moreover, the burden on the machine itself will be extremely small.

[0006]

【Example】

 Lay under the spread fabric, as you would for traditional underlayment paper. In addition, cover them with a vinyl sheet, then apply vacuum to fix the dough and cut with a knife.

[0007]

[Effect of the device]

 Therefore, by using a breathable paper-like material, paper is produced in the secondary processing process, in which holes are processed in the underlying paper, as described in (a) to (e) above. It can very effectively solve the problems of waste and scrap, the problem of its own strength, the problem of cutting accuracy, and the burden on the machine. Of course, this will also ensure stable product productivity and prevent future indirect machine failures. Furthermore, in the case of a non-woven fabric having various functions, of course, a special effect is produced. When an insulating material is used together with an antistatic vinyl sheet, even if the stretched fabric has a property of being very easily charged with static electricity, such as chemical fiber, By sandwiching the dough, electrical damage to the computer itself or the mechanical system is extremely reduced. In addition, if it is water resistant, it can be used not only with automatic cutting machines such as knives, but also with hydraulic cutting machines that use water flow, expanding the range of use with one paper. .

[Brief description of drawings]

This drawing is a cross-sectional view of a state before the cutting of the automatic cutting machine is started. With this, the basic role of the underlay paper in the automatic cutting machine will be supplementarily described. The basic outline of the vacuum system is that the air in the hollow vacuum box that is open only in one direction at the top is discharged to the outside by a turbine, etc.
While maintaining a vacuum, the stretched fabric is suction-fixed together with a non-breathable vinyl sheet. The underlay paper is for securely fixing the cloth, promoting accurate cutting and better work efficiency.
