Abstract

An embossing calender arrangement capable of embossing a thermoplastic plastics material film on either of its two major surfaces or both surfaces as desired, the embossing calender including two embossing roller sets. The roller sets are each mounted with their axes extending horizontally in one embodiment, in a common frame. The frame is horizontally displaceable beneath a film transfer arrangement by selectively displacing the frame and inserting the film into either one of the embossing nips defined in the roller sets or into both nips successively, the film can be embossed unilaterally on either of its two major surfaces or bilaterally without necessitating major adjustment of the arrangement.
