Abstract

PURPOSE:To simply manufacture a product having a delicate fringe pattern by providing an ultrasonic wave generator which is moved while being in contact with a sheet material which is brought into close contact with a flat model member to which a define shape and a defined pattern to be formed are given to cut the sheet material into the defined shape by fusion. CONSTITUTION:A sheet material T to be cut by fusion is brought into close contact with a flat model member 29 to which a defined shape and a defined pattern are given. Then, an ultrasonic wave generator 15 is brought into contact with the sheet material T and moved, to cut the sheet material T by fusion into the defined shape given to the model member 29 by means of the ultrasonic wave generator 15. At the same time, the defined pattern of the model member 29 is formed on this cut area to prevent the unwinding of the cut area. As a result, the cut area which is cut by fusion is not hardened while giving a uniform thickness, enabling the manufacture of a product having a more delicate fringe pattern.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is capable of cutting a sheet material such as a fiber cloth, vinyl sheet, or straw material into a predetermined shape, and at the same time cutting a sheet material such as a fiber cloth, a vinyl sheet, or a straw material into a predetermined shape. A fusing device is used to cut the sheet material that forms the pattern.

(Prior Art) The present inventor filed an earlier utility model registration application (Utility Model Application No. 58-17).
No. 8279), ``A woven fabric that is attached to a product such as clothing to display its product name, manufacturer name, size, etc.; The paper proposes a display plate in which a zigzag, wave, or other edging pattern is formed on part or all of the cut edge to prevent the cut edge from unraveling.

The purpose of the invention related to this earlier application is to fix the display plate to the display part of the product in its flat form, so that the mounting part does not become bulky and does not hurt the skin of the user of the product. Another object of the present invention is to improve the conspicuousness of the display plate by forming an anti-raveling border pattern on part or all of the periphery of the display plate.

There are various methods for manufacturing this display plate. For example, there is a method in which the display plate is cut with pinking scissors and then the cut ends are welded with an electric iron or a heater.

(Problem to be solved by the invention) However, the method of cutting with pinking scissors and welding with an electric trowel is not only inefficient, but also tends to cause unevenness in the thickness of the cut end during welding, resulting in processed products. It is difficult to make it uniform.

Additionally, fusing devices using heaters have conventionally been capable of only making straight cuts, and it is not possible to form fusing cuts into zigzag, wavy, or other border patterns as in the display plate according to the invention. Not only is there
Since a heater is used as a heat source, there are places where the material to be melted becomes hard due to rapid heating, making it unsuitable for forming a display plate with a uniform thickness.

In order to solve these problems, the present inventor proposed in a previous application (Japanese Patent Application No. 61-274991) a fusing process using the "manufacturing apparatus for woven fabric material made of chemical fibers". It is also possible to do so.・However, the manufacturing device according to the present invention is ``replaceable with an ultrasonic transmitter, is equipped with a curved cutting edge at the center of the circumference, and has anti-raveling at the same inclination angle on both ends of the cutting edge. This method is suitable for linearly melting sheet materials because it is equipped with processing rolls that have an action curved surface for cutting. Woven fabrics such as display plates related to display plates are melt-cut into rectangular, polygonal, or circular shapes, and some or all of the cut edges are given a zigzag, wavy, or other border pattern, or buttons or holes are made on clothing. It is not suitable for so-called cut-out processing, such as forming a star-shaped, heart-shaped cutout, or other one-point accent on the collar or pocket of clothing.

Further, since it is difficult to form a cutting edge of a predetermined shape on the circumference of such a processing roll, there is a problem that the manufacturing cost of this processing roll increases.

The present invention was made in view of the above circumstances, and
The purpose of this is that the fused cut will not become hard and will have a uniform thickness, making it possible to form a more delicate border pattern, making it possible to perform so-called cut-out processing, and further reducing the manufacturing cost of the mold material. An object of the present invention is to provide a sheet material fusing device that can cut the sheet material.

(Means for Solving the Problems) The means taken by the present invention to solve the above-mentioned problems are as follows: ``The sheet material (T) is cut by melting into a predetermined shape, and at the same time, the cut (C) is cut by the melting.

The ultrasonic generator (15) that moves while contacting is placed below, but in other words, the fiber cloth (
A similar effect can be obtained by arranging the T) in close contact with each other and providing a movable ultrasonic generator (15) above it. Moreover, in this example, *! means for moving the cloth (T) and the shape material (2)
Although the vertical movement means 9) is a manual operation, it goes without saying that by automating these operations, the display plate manufacturing apparatus (100) can be made with higher productivity.
