摘要： A wrapping machine for wrapping a generally toroidal body having an opening therethrough with an elongated length of wrapping material has supports for a body to be wrapped with the central axis of the opening through the body in a predetermined position and a shuttle for carrying a spool of wrapping material and for the controlled dispensing of the wrapping material. A wrapping frame has four transfer assemblies arranged in a generally rectangular array, one of the transfer assemblies being positionable through the opening in the body. The transfer assemblies include first and second transfer assemblies each having rails for receiving the shuttle at one end and conveying the shuttle to the opposite end, the first and second transfer assemblies being positioned at opposite sides of the rectangular array. Third and fourth transfer assemblies each have a shuttle carrier and means for conveying the shuttle carrier from one end of the transfer assembly to the other end thereof, the third and fourth transfer assemblies being positioned at opposite sides of the rectangular array and interconnecting ends of the first and second transfer assemblies. The shuttle carriers are each adapted to receive a shuttle from the rails of one of the first and second transfer assemblies, carry the shuttle along the length of one of the third and fourth transfer assemblies and release the shuttle to the rails of the other of the first and second transfer assemblies for conveyance to the carrier on the other one of the third and fourth transfer assemblies while dispensing wrapping material to wrap the coil.

摘要： A rotary chuck having a chuck body supporting a plurality of clamping jaws for movement between open and closed positions and defining a cylindrical piston chamber containing an axially movable double acting piston coupled to a jaw actuator. A plurality of springs contained within the piston chamber apply biasing force to the piston in one axial direction to urge the jaws toward closed positions. An incrementally adjustable pneumatic control system is operable to apply pressure to the piston in opposition to the springs to reduce the resultant clamping force applied by the jaws in closed position. The control system is also operable to act in consort with the springs to increase the resultant clamping force applied by the jaws in closed position.
