Abstract: 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.

Abstract: An apparatus for reshaping a container includes a number of reprofiler rollers supported by a mounting block that allows the rollers to travel along a circular path lying in a plane perpendicular to an axis along which the mounting block can be driven by a tooling ram. The mounting block and reprofiler rollers are rotated about the axis by a tooling drive shaft that is supported within the tooling ram. Removable spacers are provided between the reprofiler rollers and the mounting block and between the tooling drive shaft and the mounting block in order to provide a way of adjusting the radial and axial positions respectively of the rollers.

Abstract: An apparatus and method is shown for reforming the bottom of a container. A number of tooling rams each have a reforming roller supported by a roller mounting block that allows the reforming roller to travel along a circular orbital path of varying diameter in a plane perpendicular to the roller mounting block axis and having a center of curvature position coextensive with the container axis. Guide cams that slide along cam surfaces formed in slots in the roller mounting block are supported on a cam mounting block. The cam mounting block is supported on a tooling drive shaft that rotates the cam mounting block about its axis coextensive with the container axis while 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 cam mounting block is converted to radial and rotational movement of the reforming roller through the interaction of the guide cams with the roller mounting block.
