A device for engaging articles of varying thicknesses includes an anvil defining a gripping surface, a gripper finger assembly, and a finger actuator means for pivoting the gripper finger assembly with respect to the anvil. The gripper finger assembly includes a gripper finger, a finger support, and a spring which engages the finger and finger support and spring biases the finger into a neutral position with respect to the finger support. The finger may be moved out of its neutral position in either direction when forces in excess of predetermined forces are applied to the finger.
