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.
