Specimen sheet extraction device for printing machine sheet deliverer has setting angle between pick-up fingers and horizontal plane of stack that can be varied by displacing fingers

摘要

The device consists of front stops (9) that fix the edge of the deliverer stack (6) and pick-up fingers (19) that can be deployed above the stack to pick up the sheets in the front region to enable the extraction of specimen sheets. The setting angle (alpha1, alpha2) between the pick-up fingers and the horizontal plane of the stack can be varied by displacing the fingers.
