本発明はプラスチック発泡体シートの切断方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for cutting plastic foam sheets.
従来、プラスチック発泡体シートを切断するには丸刃、
鋸刃等を有する切断機が使用されていた。Traditionally, a round blade is used to cut plastic foam sheets;
A cutting machine with a saw blade, etc. was used.
しかし上記従来の切断機を用いると切屑が多量に生じ、
プラスチックは静電気が発生し易いので切屑がプラスチ
ック発泡体シートの切断部付近に付着し、これを拭き取
るために大きな手間を要する。However, when using the above-mentioned conventional cutting machine, a large amount of chips are generated.
Since plastic easily generates static electricity, chips adhere to the vicinity of the cut portion of the plastic foam sheet, and it takes a great deal of effort to wipe them off.
本発明は上記従来の課題を解決するための手段として、
プラスチック発泡体シートをウォータージェット切断機
によって切断するものである。The present invention, as a means for solving the above-mentioned conventional problems,
A plastic foam sheet is cut using a water jet cutting machine.
本発明の対象とするプラスチック発泡体シートとしては
ポリエチレン、ポリプロピレン、ポリスチレン、ポリ塩
化ビニル、ポリウレタン等のプラスチックの発泡体シー
トがある。該プラスチック発泡体シートの片面または周
面にはポリエチレン。Plastic foam sheets to which the present invention is applied include foam sheets of plastics such as polyethylene, polypropylene, polystyrene, polyvinyl chloride, and polyurethane. Polyethylene on one side or the circumference of the plastic foam sheet.

エステル等のプラスチックのフィルムが積層されていて
もよい。Plastic films such as polypropylene, polystyrene, polyvinyl chloride, and polyester may be laminated.
本発明に用いられるウォータージェット切断機とはノズ
ルより超高圧水を噴射せしめて該水圧によって対象物を
切断するものである。The water jet cutting machine used in the present invention is one that injects ultra-high pressure water from a nozzle and cuts an object using the water pressure.
本発明においてノズルより超高圧水を噴射せしめてプラ
スチック発泡体シートを切断すると、生ずる切屑の量は
丸刃や鋸刃で切断した場合より少ないし切屑は該水によ
り飛ばされてプラスチック発泡体シートには殆ど付着し
ない。In the present invention, when ultra-high pressure water is jetted from a nozzle to cut a plastic foam sheet, the amount of chips generated is smaller than when cutting with a circular blade or saw blade, and the chips are blown away by the water and cut into the plastic foam sheet. hardly adheres.
したがって本発明においてはプラスチック発泡体シート
に切屑が殆ど付着しないので切断後拭取りの手間がかぎ
らず、切断工程が従来よりも大巾に合理化される。Therefore, in the present invention, since almost no chips adhere to the plastic foam sheet, there is no need for wiping after cutting, and the cutting process is much more streamlined than in the past.

（１）Ａが形成されている。The present invention will be explained with reference to an embodiment shown in Figs. 1 to 5. Fig. 1 shows a laminated sheet (lO) of a polystyrene foam sheet (11) and a polystyrene film (12) that is vacuum-formed to form an automobile. The main body (1) of the masking material that protects the air inlet at the bottom of the bumper from painting is shown in a molded state, and the vertical bar formed inside the air inlet is fitted into the main body (1) of the masking material. Fitting groove (1) A,
