Apparatus (10) for engaging at least a portion (20b) of a signature (20a) in a hopper (14) and moving the portion relative to a stack of signatures (20) in the hopper includes a stem member (110) and a suction cup (150) mounted on the stem member. The stem member (110) is supported for movement toward and away from the stack of signatures (20) A venturi tube (160) is provided in the stem member (110) for generating a vacuum which is communicated to the suction cup (150). The vacuum in the suction cup (150) causes the portion (20b) of a signature (20a) to be gripped by the suction cup (150) and moved relative to the stack of signatures (20) in the hopper (14) upon movement of the stem member (110).
