Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet material or a string-like body and a cutting device therefor, and more particularly, to a sheet having a cut surface melt-processed, and a vicinity of the cut surface also melt-processed. The present invention relates to a material and a cutting device therefor.

[0002]

2. Description of the Related Art There are various conventional methods for cutting a sheet material made of a thermoplastic material. The most widely used methods include a method in which a sheet material is pressed and cut with a mold having a sharp cutting blade, a method in which cutting is performed with scissors, and the like.

[0003] However, the cut surfaces of sheets and strings cut by these cutting methods are in a state of being cut off, so to speak, without any processing. Therefore, when a woven cloth, a net cloth, or the like is cut, there is a problem that fluff is generated on the cut surface or the yarn is unwound from the cut surface, as shown in FIG.

On the other hand, in order to prevent such a problem, there is a method of cutting using ultrasonic waves or heat. According to this method, since the cut surface is cut while being melted, the fluff and the yarn can be prevented from being separated by melting the cut surface.

[0005] However, the conventional cutting method using heat or ultrasonic waves is the same as the above-mentioned method in that a method in which cutting is performed by pressing the upper surface with an acute-angled cutting blade is employed. For this reason, the tip of the cutting blade is worn according to use. Therefore, FIG.
As shown in (1), the sheet material cannot be completely cut by the cutting blade, and a very thin thin film is formed at the tip.

[0006] Such a thin film at the tip has a drawback that it is very fragile and easily peeled off because it is molten, and it is easy to generate dust.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems. The problem to be solved is to cut perpendicularly to the sheet plane or the longitudinal direction of the string, form a cut surface in a plane and form a uniform molten state on the cut surface to prevent fraying,
It is another object of the present invention to provide a sheet material or a string-shaped body having a melt-processed portion such as a fusion plane, an emboss, or a pattern formed in the vicinity of the cut surface for strengthening the cut surface or improving aesthetics, and a device for cutting the same.
