Abstract

PURPOSE:To prevent generation of fluff generated by a non-woven fabric from a hole in the stage of opening a hole to a floppy jacket consisting of a plastic sheet to which the non-woven fabric is stuck by blowing an assisting gas to the hole part simultaneously with opening the hole with irradiation of a laser. CONSTITUTION:A laser 5 is irradiated to a floppy jacket formed by sticking a PVC sheet 2 and a non-woven fabric 3 by a laser working machine in the stage of opening a hole to said jacket. The sheet 2 and the fabric 3 irradiated with the laser are instantaneously evaporated by high temp. and a hole is formed therein. An assisting gas 6 is at the same time blown thereto to blow off the evaporating matter. A part 7 of the gas 6 heats the end face of the fabric 3 cut by the laser 5 and the fabric shrinks from the cut end face of the PVC2 to the inside 8, by which the hole having no fluff is worked.

This relates to a processing method that prevents the occurrence of fluff. Floppy jackets are usually about 0. Non-woven fabric is pasted onto a double-thickness plastic sheet such as polyvinyl chloride (PVC), and predetermined holes are drilled into it. An example of a conventional hole machining method is as shown in FIG. 1, in which a nonwoven fabric is pasted between an upper punching die (1) and a lower die (4). In this method and other mechanical cutting methods, the floppy jacket P
VC sheet (2) is cut cleanly, but non-woven fabric (3)
Regarding the part, there was a problem that the fiber part contained therein was not completely cut and became fluff, which sagged from the cut end of the PvC sheet (2). Furthermore, PVC sheet (
The cut end of 2) and the cut end of nonwoven fabric (3) are the same, and the cut end surface of nonwoven fabric (3) is also cut, so even if there is little fluff immediately after processing, it is difficult to move the workpiece. Yes, there was a problem with fluff appearing.

本発明は、これらの欠点を解消し、ケバを発生すること
なくまた、加工後の移動によってもケバが発生しにくい
という方法を提供するものである。The present invention eliminates these drawbacks and provides a method that does not generate fluff and is less likely to generate fluff due to movement after processing.
