Abstract: A system for forming a continuous extrudate of a heated soft thermoplastic material (4) into a continuous sheet (232) of a cooled rigid thermoplastic material having a plurality of recesses (234) formed in one surface thereof and a plurality of projections formed on the other surface thereof by feeding successive portions of a heated soft extruded thermoplastic material (4) onto successive portions of a forming cylinder (30) having a generally cylindrical outer peripheral surface (32) having a plurality of recesses (34) formed therein and applying a vacuum through the recesses (34) to draw areas of successive portions opposite to the recesses (34) into conformation with the recesses (34) and cooling the thermoplastic material by moving a cooling fluid over the inner peripheral surface of the forming cylinder and removing the successive portions to form a continuous sheet (232) of a rigid thermoplastic material having a plurality of recesses (234) formed in one surface thereof and a plurality of projections formed on the other surface thereof.
