Abstract (en)
[origin: US4863086A] A device for supplying a machine working on a web of material in a stopped position particularly for a flat cutting press and in the vicinity of an intake roller and downstream thereof, in the direction of advance of the web, the device includes an oscillating roller. This roller is mounted for rotation on a support adapted to oscillate about the axis of the intake roller. The oscillating roller is driven in rotation on itself from the intake roller, via a transmission mechanism in such a manner that the peripheral speed of the oscillating roller is identical to that of the web of material winding around part of the periphery of this oscillating roller. A mechanism is provided for provoking a movement of oscillation of the support and of the roller that is bears. Other means mechanism is provided for maintaining the tension of the web disposed at the entrance of the machine and for cyclically controlling the movement of oscillation of the support and of the oscillating roller that it bears so that the length of the part of the web between the intake roller and the machine is lengthened or shortened to provide the desired law for the advance of the web in the machine and a law which includes in particular a stop phase in the machine.
