ABSTRACT:
A cartridge such as a caulking cartridge is formed of extruded and injection molded resin parts assembled and welded together. A resin tube is extruded and cut off in lengths to form cartridge barrels, and single-piece resin end caps and nozzles are injection molded. The barrel cylinders are fed to an assembly station where the end caps and nozzles are fitted over one of the severed ends of the barrel cylinders in concentric registry with the barrel cylinders and are successively welded to the barrel cylinders to form cartridges.
