Abstract
An apparatus and method for fabricating a consolidated assembly of cathode material in a dry cell battery casing having a closed end and an open end are disclosed. The casings are moved in a path to a selected transfer region on a circular locus, into registry with a die assembly, and along an arc of the circular locus in the transfer region at the same angular velocity as the die assembly. Each casing is engaged by a rotating die assembly in which a quantity of fluent cathode material has been deposited in an upwardly open receiving chamber of the lower die assembly. The casing is retained in position on the lower die assembly while a core pin and annular shoulder punch are elevated through the receiving chamber to force the cathode material into the casing and to compact the cathode material into an annular configuration.
