    摘要: A thermoforming packaging machine includes a forming station for thermoforming troughs in a film web, a filling path for filling products into the troughs, a sealing station for sealing the troughs, a chain guide for guiding a transport chain for the film web, a transverse cutting device for cutting the film web in a direction transverse to the transport direction, a longitudinal cutting device for cutting the film web in the transport direction, and a control device for controlling processes running on the thermoforming packaging machine. The transverse cutting device comprises a film punch, an adjustment drive which can be controlled by the control device for closing and opening the film punch, and a detection unit which is connected to the control device and which has at least one sensor which is configured to detect, per processing cycle, a force progression occurring at the film punch during opening and closing.
