APPARATUS FOR PRODUCING A PLASTIC SHEET AND PROCESS FOR PRODUCING A PLASTIC SHEET USING THE SAME

摘要

The invention, object of the present invention is a polyolefin-based resin of the laminated sheet or thick single-layer sheet, there is no warp, the planarity is good, also it shortens the cooling time, to provide a plastic sheet manufacturing apparatus and manufacturing method for the productivity good manufacturing will one to, for as the solving means, (a) a polyolefin-based resin plastic sheet manufacturing apparatus and (B), the cooling available metallic endless (無端) belt and down by the rotational movement and the cooling water to cool the sheet on both sides of the high-temperature a cooling mechanism arranged to one characterized in that it provides a plastic sheet manufacturing apparatus and a manufacturing method having at least.
