ABSTRACT OF THE DISCLOSURE A thermoplastic sheet comprising a lamina-bearing base is produced by feeding a heat-plastified laminated rod in- to a conventional sheet-forming die. The laminated rod is formed using an adaptor die which is interposed between a rod- forming die and the sheet-forming die and which deposits a layer of heat-plastified material constituting the lamina on a segment of the peripheral surface of the cross-section of a heat-plastified rod of the base material, as the rod is extruded from the rod-forming die. The sheet-forming die converts the heat-plastified laminated rod into a laminated sheet.
