Abstract

PURPOSE:The prepare a synthetic resin molded article having a multiple layer structure of desired shape at desired position, by attaching a plate to restrict the flow width of resin to a die for the co-extrusion of multilayered synthetic resin sheet, thereby controlling the flow width of one or more molten resins.
