To provide a method and an apparatus for manufacturing an uneven thickness resin sheet which can prevent defective cutting and the peeling of a protective film during the cutting of the uneven thickness resin sheet.
In the method for producing the uneven thickness resin sheet, a molten resin extruded from a die 16 is pressed between a mold roller 20 and a nip roller 18 to mold the uneven thickness resin sheet S. The sheet S, after being peeled off from the mold roller 20 by a peeling roller 22, is cut in a desired length by a cutter 32. The sheet S is cut while the sheet S is pushed by an elastic body whose shape is adjusted in advance according to the sheet S. In this way, since the sheet S can be cut while being pushed by the elastic body over its entire width, the defective cutting of the sheet S and the peeling of the protective film can be prevented.
