Abstract: An apparatus and method are disclosed for removing a sheet such as a release sheet (18) in adherence with a workpiece such as a foam pad (12). The release sheet is contacted with a knife to form a slit, a needle then enters and engages the slit to lift a portion (102) of the release sheet, and a peeler (48) then grasps the lifter portion and peels the release sheet from the workpiece.

Abstract: A device for exchanging simple tools that do not need utility service is adapted to facilitate coupling one such tool to, and uncoupling it from, a movable robotic arm. The device comprises an attaching member attachable to the tool, a supporting member connected to the arm and having an open slot therein and a recessed upper surface adjacent to the slot, and a retaining member movably mounted to the arm above the supporting member and spring-biased toward the supporting member slot and upper surface. The attaching member, attached to the tool, is received by the open slot, supported by the recessed upper surface, and yieldably retained there by the spring-biased retaining member during use. The attaching member is then withdrawn from the slot, upper surface, and retaining member, and returned to a storage rack located nearby.
