发明名称 PRODUCTION OF THERMOPLASTIC RESIN SHEET
摘要 PROBLEM TO BE SOLVED: To industrially advantageously produce a thermoplastic resin sheet without defect, line, stripe and fluctuation of thickness and with good appearance. SOLUTION: A method for producing a thermoplastic resin sheet has a constitution comprising a process wherein a molten thermoplastic resin sheet 2 extruded on the surface of a rotating cooling drum 4 from a die 1 is hermetically adhered on the surface of the rotating cooling drum 4. When temp. T2 of the thermoplastic resin sheet 3 exists within a range of formula [ Tm-200]<=T 2<=[Tm-50] (wherein Tm is m.p. ( deg.C) of the thermoplastic resin), a surface protective sheet 9 is sticked on the surface of the thermoplastic sheet 3.
