Abstract
An apparatus for removing paper products from a stack on a hopper comprises a rotatably mounted gripper drum for rotating about a central axis at a substantially constant angular velocity. A stationary cam is rigidly mounted adjacent the gripper drum. A gripper mechanism is mounted on the gripper drum and rotates with the drum. The gripper mechanism is provided for gripping a paper product, removing the paper product from a stack and for entraining the paper product with the rotating gripper drum. A linkage mechanism which is also mounted on the gripper drum and which rotates with the drum is provided for angularly displacing the gripper mechanism relative to the gripper drum, i.e. to accelerate and to decelerate the gripper, and for operatively linking the gripper mechanim with the cam.
