ABSTRACT:
In order to increase considerably the output of a rotary feeder (6) for removing individual blanks (1) from a stack (2), the invention proposes that the speed of the rotary movement of rotary suckers (7) is slowed down while they are being pressed against the blank (5) that is to be removed. This retardation operation is brought about by a special gear unit that drives a rotor (12) to which the rotary suckers (7) are attached.
