MANUFACTURING METHOD OF A THERMOPLASTIC RESIN SHEET FOR SUCCESSIVELY AND EASILY OBTAINING THE THERMOPLASTIC RESIN SHEET AND REDUCING THE SIZE OF A MANUFACTURING DEVICE OF THE THERMOPLASTIC RESIN SHEET

摘要

PURPOSE: A manufacturing method of a thermoplastic resin sheet is provided to successively and easily cut a successive sheet extruded through a die although the successive sheet is not sufficiently cooled. CONSTITUTION: A manufacturing method of a thermoplastic resin sheet comprises steps of heating and melting thermoplastic resin(2); obtaining a thermoplastic successive resin sheet(3) with thickness of more than about 3 mm by successively extruding the melt resin in a sheet shape through a die(D); and pressing at least one cutting blade(C1,C2) on the thermoplastic successive resin sheet to cut the thermoplastic successive resin sheet into an individual sheet(1) while feeding the thermoplastic successive resin sheet in an extruding direction.
