摘要
A method and apparatus for constructing a dispensing end portion of a cartridge used to hold and dispense food sauce. A flat end disk is held in a transfer pocket and moved by a disk punch through a die opening smaller in diameter than the disk. The die bends the peripheral portion of the disk into a skirt. The disk punch inserts the disk into the open end of a cartridge body and against a mandrel positioned so that an end portion of the cartridge body extends beyond the skirt. Heat is applied to melt thermoplastic coatings on the disk and cartridge body. A crimping device crimps the end portion oft he cartridge into a flange which is bent against the disk and folds the skirt to form a lip doubled over on the peripheral area of the disk. Thermoplastic coatings bond to weld the flange to the disk with the lip enclosed between them.
