Abstract:
An apparatus for a stepwise periodic feeding of a strip-like workpiece,having a first pressing member and a second, pressing member which co-operates with the first pressing member;which first pressing member is adapted to periodically extend a pressure onto a strip-like workpiece received between the first pressing member and the second pressing member for a periodic clamping of the strip-like workpiece;which second pressing member is driven periodically in order to periodically feed the strip-like workpiece received and clamped between the first pressing member and the second pressing member;and having a first arresting member and a second arresting member which co-operates with the first arresting member;which first arresting member is periodically moveable in order to press the strip-like workpiece periodically against the second arresting member in order to temporarily arrest the strip-like workpiece;said apparatus comprising a drive shaft and an oscillating cam drive apparatus arranged longitudinally displaceable on the drive shaft, which oscillating cam drive apparatus is drivingly connected to at least the second pressing member;and comprising further one single cam disk which is firmly connected to the drive shaft, which cam disk is drivingly connected via a transmitting linkage arrangement to the first pressing member and to the first arresting member, as well, whereby the periodic movement for exerting a pressure by the first pressing member and the periodic movement for a clamped arresting by the first arresting member are controlled by said one single cam disk.
