Abstract:
1. A method for manufacturing a molded multilayer article by molding a multilayer sheet comprising a plurality of polymer layers, said method 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 respectively through the T dies; forming an intermediate molten multilayer by superposing and laminating the monolayers extruded through the T dies outside the multiple T die 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 at a position below the die slot openings of the T dies of the multiple T die with respect to a direction in which the monolayers are extruded.
