ABSTRACT:
A device for optionally or selectively drawing in a cutout from a stack of several cutouts, or taking over a cutout from a separating cutting device, which separates the cutout from a material web, includes a vacuum guide roller in which the cutout coming from the stack or the cutout that has been taken over can be passed to a subsequent work station for processing of the cutout in a work cycle, at a cycle speed. This device reduces both production costs and machine maintenance costs, reduces the amount of space required for the machine and generates less noise. The vacuum guide roller is configured as a segment roller in which optionally or selectively the cutout can be drawn in from the stack and accelerated to the cycle speed, or the cutout taken over from the separating cutting device can be accelerated to the cycle speed.
