PRODUCTION OF LAMINATED SHEET

摘要

PROBLEM TO BE SOLVED: To continuously produce a laminated sheet by laminating a resin impregnated base material obtained by impregnating a base material with a resin compsn. and a metal foil so that the metal foil is arranged to a surface layer to bond them under pressure by a laminate roll and subsequently heating the pressure bonded object in a heating curing oven so as to hardly form wrinkle-like recessed parts on the metal foil on the surface of the laminate. SOLUTION: When a pressure bonded object 15 is heated in a heating curing oven 17, a free roll 16 arranged so that the part being in contact with the pressure bonded object 15 is freely rotated toward the oblique outside direction with respect to the advance direction of the pressure bonded object 15 is brought into contact with the metal foil 13 of both lateral end parts of the pressure bonded object 15 to stretch the metal foil 13 laterally.
