Abstract: Apparatus for trimming cylindrical cans wherein each can is orbited about a central turret axis while being rotated about its longitudinal can axis is disclosed. The cans are successively mounted with vacuum onto a support mandrel located on a support shaft within each of plural cartridge assemblies mounted at circumferentially spaced intervals on a turret disk. The can is firmly secured to the mandrel by vacuum so that the open end portion of the can body projects between an outside circular cutting knife and an inside trimming edge disposed within the open end. As the cartridge orbits about the turret axis on the shaft axis, the inside trimming edge is radially displaced by camming action into contact with the open end portion of the can body and the outside cutting edge to generate cutting forces for trimming the portion.

Abstract: The can trimmer includes first and second supports adjustably mounted on bars for adjustably spacing the supports from one another dependent upon the height of the cans to be trimmed. The supports mount a motor-driven splined shaft for rotating first and second carrier wheels and star wheels between the carrier wheels. Cam-actuated pushers are mounted on the pusher carrier wheel and mandrels are carried on the other carrier wheel in axial opposition to the pushers. Cam-actuated trim heads are pivotally carried by the second carrier wheel for movement toward and away from the mandrels, respectively. Upon disposition of cans on the star wheels between the pushers and mandrels, the pushers carry the cans onto the mandrels for cutting by the trim heads. Air pressure pushes the cans off the mandrels in following engagement with the pushers for discharge.

Said device comprises a shaft, slides arranged parallel to the shaft axis and provided with mandrels for receiving the bellows, and tool units, each tool unit comprising a cutting tool in the form of a pair of cutters. One of said cutters, cylindrical in shape, is installed in the hollow holder coaxially with its inner surface which is eccentric relative to its outer surface. The other one of said cutters is made in the form of a ring consisting of two half-rings, the longitudinal axis of said ring being coaxial with the axis of the inner surface of the hollow holder at the moment of receiving the bellows to be cut-off. The half-rings are adapted for closing radially when clamping the bellows and for opening when releasing the bellows after its throat has been cut-off.

Abstract: A device for cutting lengths of tubing from a longer tube utilizes an external pair of cutting dies and an internal pair of punches. An eccentric relative motion ("shimmy") of the cutting dies results in the desired cutting of the tube. The punches are inserted into the tube from the end of the tube from which the length of tubing is to be cut. A restraining arrangement prevents the punches from moving farther along the tube than is desired, while a punch positioning mechanism prevents movement of the punches toward the open end of the tube. Thus, the internal punches are accurately positioned with respect to the external cutting dies. A centering arrangement is utilized to insure coaxiality of the punches.
