Abstract
A first clamping member allocated to the feeding of the web co-operates with a second clamping member allocated to the feeding of the web in order to clamp the web for a feeding thereof. The first clamping member is controlled by a cam disk via lever arm members. A first arresting member co-operates with a second arresting member in order to clamp the web for an arresting thereof. The first arresting member is controlled from the same cam disk via lever control members.
Claims5
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.
An apparatus for stepwise feeding of a strip-like workpiece, the apparatus comprising:
- first and second pressing members co-operating to receive a strip-like workpiece between them for stepwise clamping and feeding of the strip-like workpiece;
- first and second arresting members for arresting the strip-like workpiece alternately with the stepwise clamping and feeding;
- a rotatable drive shaft;
- an oscillating cam drive apparatus longitudinally displaceable on the drive shaft and drivingly connected to the second pressing member;
- only one single cam disk connected to the drive shaft for rotation therewith;
- and
- a transmitting linkage drivingly connecting the one single cam disk to the first pressing member and to the first arresting member for the stepwise clamping and feeding and arresting of the strip-like workpiece by the one single cam disk.
