Abstract
A signature handling apparatus includes a rotatable gripper drum having at least one gripper for gripping the folded leading edges of signatures. A rotatable transfer drum assembly transfers signatures from the gripper drum to an opener drum. The transfer drum assembly includes a transfer gripper. First drive means rotates the gripper drum to move the folded signatures at a first surface speed in a first direction adjacent to the transfer drum. Second drive means moves the transfer gripper at a second surface speed in the first direction into engagement with the trailing edge of one respective signature on the gripper drum. The second surface speed is greater than the first surface speed. The second drive means rotates the transfer drum to move the transfer gripper and the one signature toward the opener drum. The opener drum has means for assisting in opening the one signature.
