Abstract
A generally continuous strip of thermoplastic material is deformed into a desired preformed configuration, while retaining continuity with the generally continuous strip to form a chain of the configurations. The chain remains continuous with the generally continuous strip. End portions of the chain are severed so as to form a stack of preformed configurations to be used in the formation of a dispensing cartridge.
