METHOD OF MANUFACTURING RESIN SHEET WITH UNEVEN THICKNESS AND DEVICE FOR MANUFACTURING RESIN SHEET WITH UNEVEN THICKNESS

摘要

A molten resin extruded out of a die (16) is sandwiched and pressed between a pattern roller (20) and a nip roller (18) to form a resin sheet (S) having an uneven thickness, the resin sheet (S) is separated from the pattern roller (20) by a separating roller (22), and the resin sheet (S) is cut into a desired length by a cutting machine (32).  The cutting of the resin sheet (S) is performed with the resin sheet (S) pressed down by an elastic body having a shape which is previously adjusted according to the resin sheet (S).  The resin sheet (S) can be cut while being pressed down by the elastic body across the entire width of the resin sheet (S), and this prevents a cutting failure and peel-off of a protective film from occurring.
