a thermoforming system for carrying out a method for processing two different thermoplastic films has a thermoforming station for processing the different films , a transport device for transporting the film to the thermoforming station , and a connecting station for connecting successive blank cuts so as to form a film strip . cuts of the one or the other film are selectively and variably brought on request in a conveyor through the thermoforming system , such that different successive cuts are conveyed by the conveyor to the thermoforming station and processed therein , and two successive cuts are joined into a film strip , either edge to edge or with an overlap .
