Abstract:
A device for driving a stamping foil over a path through a stamping machine is disclosed herein. The driving device comprises two foil-introduction chain-like elements and a drive member coupled to the foil-introduction chain-like elements for driving the foil-introduction chain-like elements notably through a platen press of a stamping machine. The driving device further comprises at least one first load-measurement device comprising a first detector configured to measure a parameter indicative of the load applied by the drive member for driving the foil-introduction chain-like elements in a first direction, the at least one first load-measurement device being connected to a stamping-machine control unit configured to stop the driving by the drive member when the parameter indicative of the load applied by the drive member and measured by the first detector crosses a threshold.
