ABSTRACT:
An apparatus for removal of adhesive-backed objects attached to a liner with the objects and liner constituting a pad which includes a curved surface and a removal head. The curved surfaces preferably a drum, is adapted to receive the pad of the adhesive-backed objects for disposition around the drum with a radius sufficient to spread the individual objects of the pad apart. The removal head is positioned adjacent the drum for selectable engagement with the objects of the pad. The removal head includes at least one piston movable between a first position out of contact with the pad and a second position where the piston contacts the pad and applies a force thereto to securely maintain the position of the pad around the drum. The removal head further includes at least one gripper member positioned for engagement with an individual object of the pad. The gripper member is movable between a first position away from the drum and a second position adjacent an individual object attached to the liner. The gripper member moves from the first to the second position when the piston is applying a force against the pad. The gripper member is pivotable between an open and closed position to securely engage the individual object attached to the liner of the pad at which point the gripper member retracts radially away from the drum and removes the individual object from the liner of the pad with the piston holding the pad against the drum.
