Abstract
An improved apparatus and method for calendering of thermoplastic material are disclosed. An endless belt is interposed between the calendered material and the last calender roll which belt conveys the thermoplastic calendered sheet around the last calender roll and toward the stripper roll. The thermoplastic calendered sheet does not come into contact with the final calender roll surface. After cooling the film should strip easily off the endless belt. Consequently, problems originating in sheet adhesion to the final calender roll will be reduced if not eliminated.
