A sucker adjustment device including a moving lever having a cam surface adjacent its far end. An axis is located adjacent the near end and a first cam follower is mounted intermediate the ends. The first cam follower bears against an actuating cam which causes the former to move between an extended position, wherein the sucker cup attached thereto contacts the bottom newspaper of a stack, and a retracted position, wherein the sucker cup is out of the path of the lowest newspaper. There is an actuating lever pivotally mounted about the axis and carrying an arm between its distal end and the axis. There is a second cam follower on the arm at a point remote from the actuating lever and bearing against the cam surface. A pivot adjacent the rotating end of the sucker bar spaced apart from the sucker cup permits the sucker bar to move between its extended and retracted positions. By this means, appropriate movement of the actuating lever will adjust the extended position of the sucker cup with respect to the newspapers without changing its retracted position.
