げられる。Hollow plate-like bodies with a rib structure made of thermoplastic plastic have recently become popular for their light weight and heat insulation properties. Demand is increasing due to its characteristics such as heat resistance, high strength, and toughness. Specific examples include building materials such as greenhouses, solar thermal equipment, frozen food equipment, and packaging materials.

、更に現場にて所定の大きさに切断されて使用される。This plastic hollow plate-shaped body is manufactured as a long piece by i-extrusion molding or the like, and is appropriately cut into a size suitable for transportation, and further cut into a predetermined size at the site for use.

が多かった。A metal circular saw or a guillotine-type cutter is usually used for these cuts, but when the former is used, the circular saw rotates at a significantly higher speed than the feed speed of the product, causing rapid heat generation. Not only was it not possible to make a sufficient V-cut using the cutting method, but also chips entered the hollow portion, and the smoothness of the cut surface was also insufficient. When using the latter type of guillotine cutter, no chips were left in the hollow part, but the rib structure of the cut surface was often significantly deformed due to pressure being applied to cut the material.

Specifically, this is possible by adjusting the rotational speed of the rotary drive motor of the rotary round blade, the rotary roll, and the feeding roll of the hollow plate-like body. Specifically, the feeding speed of the hollow plastic plate is preferably 5 to 2 m/f+, and the rotating round blade and rotating roll are determined accordingly.
