<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a resin sheet, in which the resin sheet is continuously cut during conveyance without generating cutting powder even when a thick sheet of 1 mm or more is cut. <P>SOLUTION: The method of manufacturing a resin sheet includes an extrusion process 112 for extruding molten resin into a sheet form from a die 12; a sheet forming process 114 for molding a sheet by nipping the extruded resin sheet 14 with a mold roller 16 and a nip roller 18 and cooling and solidifying it; a peeling process 115 for peeling the resin sheet 14 from the mold roller 16; and a cutting process 124 cutting both ends of the resin sheet 14 having the thickness of 1 mm or more with an ultrasonic cutter 174 along the conveying direction. The temperature of the cutting part of the resin sheet 14 is (Tg-50) to (Tg+100)°C, wherein Tg is the glass transition temperature of the resin. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
