Patent ID: 7125508

Claim:
A method for manufacturing a molded multilayer article by molding a multilayer sheet consisting of a plurality of polymer layers, comprising: extruding a plurality of monolayers of molten polymers by forcing the molten polymers into a multiple T die formed by an assembly of T dies so that the molten polymers are extruded from slot openings of respective T dies forming the assembly; forming an intermediate molten multilayer by superposing and laminating the monolayers extruded through the T dies outside the respective T dies while the polymers are in a molten state or a semi-molten state; feeding the intermediate molten multilayer to a compression mold having a bottom half mold and a top half mold by advancing the multiple T die into a space between the bottom half mold and the top half mold; cutting the intermediate molten multilayer to a predetermined length; and molding the intermediate molten multilayer in the compression mold into a multilayer article of a desired shape, wherein the intermediate molten multilayer is cut in a plane including an exit of a slot opening of the respective T dies, and wherein a cutting process comprises: extending a metal wire in a plane intersecting a plane including the intermediate molten multilayer so as to be able to be brought into contact with end surfaces of the T dies of the multiple T die in which the die openings of the T dies open; and moving the metal wire along the end surfaces of the T dies along the width of the intermediate molten multilayer.
