A rotatable forming apparatus and a method for modifying a shape of a container. The rotatable forming apparatus includes a frame and a forming turret assembly. The forming turret assembly includes a drive shaft, a fixed turret portion, a turret starwheel, an axially moveable turret portion and forming ram assemblies. The forming ram assemblies extend around and connect to the axially movable turret portion. Each of the forming ram assemblies includes cam followers, a forming die, a knockout tooling device and a drive cylinder. The cam followers are configured to follow the cam as the forming ram assemblies rotate around the stationary cam. The forming die is operatively connected to the cam followers such that the forming die moves in the vertical direction while following the cam. The drive cylinder causes axial movement of the knockout tooling device and is configured to operate independently of the forming die.

Forming apparatus

A machine arrangement that operates on a plurality of articles includes a plurality of machines arranged to cooperate with each other in a manner to form a machine arrangement. Each machine includes a modular base, a transfer star wheel, and a turret mechanism configured to perform a working operation on an article. The turret mechanism includes a turret star wheel. A central axis of the transfer star wheel is approximately 45 degrees below horizontal relative to a central axis of the turret star wheel. The turret mechanism includes a cantilevered portion overhanging a portion of the base.

Can processing machine with cantilever design

A flange forming process uses first and second stages. The first stage produces a partially formed flange on an article. The second stage forces the partially formed flange into a die so a stepped surface of a knockout punch that is disposed in the die, produces a predetermined can height such as the FFCH (Factory Finished Can Height) while the retaining die limits the outside diameter of the flange.

Flanging process improvement for reducing variation in can body flange width

An apparatus and method is shown for reforming the bottom of a container. The container is supported during processing by a container holder. A number of tooling rams each have a reforming roller supported by a pivot roller shaft that is in turn connectedly pinned to one end of a pivot arm. The opposite end of the pivot arm is connectedly pinned to an eccentric lug on a pivot base that is connected to a tooling drive shaft. The reforming roller is restrained axially by roller guide disks mounted to the tooling rams and is driven by the pivot arm such that the reforming roller travels along a circular orbital path of varying diameter in a plane perpendicular to the central axis of the pivot roller shaft and having a center of curvature position coextensive with the container axis. The tooling drive shaft is supported rotatably in and moved axially with a tooling ram that moves axially toward or away from the container. Axial and rotational movement of the pivot arm is converted to radial and rotational movement of the reforming roller as a result of the pinned connections between the pivot arm and the pivot base and the pivot arm and the pivot roller shaft, and as a result of the restraint on axial movement of the reforming roller. The container holder supports the container during reforming either on portions of the outer periphery of the container that are axially offset from a plane defined by the circular orbital path traveled by the reforming roller, or only along an annular arcuate portion of an annular flange-like ridge around the base of the container.

An apparatus for performing reshaping operations on a can, with the apparatus being modular in construction. The modular construction allows for the easy add-on of additional processing stations for performing additional reshaping operations to the cans. Each module is readily connected to an adjacent module in such spaced relationship that cans are transferred directly from can support pockets that hold the cans during processing on one module to can support pockets that hold the cans during processing on the adjacent module, without the need for any conveyors or track work to transfer the cans. The modules are cast with internal chambers that form vacuum chambers, gear chambers, and/or pressurized air passageways. The internal chambers of one module can be interconnected with corresponding internal chambers in adjacent modules.
