Manufacture of composite
专利汇可以提供Manufacture of composite专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a laminated material suitable for use for a filtering medium, drainage material of civil engineering and packaging materials for various kinds of articles, by a method wherein a polyolefin sheet is molded into a corrugated sheet, crest parts of which in a molten state are heated by pressing and joining a polyolefin series porous film or sheet-like material onto the crest parts.
CONSTITUTION: A polyolefin resin sheet 2 extruded through an extruding machine 1 and in a molten state is held between corrugated rolls 3, 4 and made into a corrugated sheet. The polyolefin resin sheet 2 made into the corrugated sheet is moved under a state wherein the same is held on the surface of one side corrugated roll 4 and a polyolefin series porous film or sheet-like material composed of a sheet 5 is pressed and joined onto crest parts of the corrugated sheet by a manual pressure roll 6 while a molten state of the corrugated sheet is being kept on through heating by a heater 7. With this construction, an obtained polyolefin corrugated board is made into structure wherein a porous film or sheet is provided on one surface of the corrugated sheet.
