ABSTRACT:
The specification and claims disclose a method and apparatus for performing two manufacturing steps substantially simultaneously during the formation of a caulking tube cartridge. In general, the disclosed method includes the steps of providing a generally cylindrical anvil member adapted to be received in the piston end of the caulking tube; providing a flange ring member including a cylindrical open-ended section having a radially-extending flange; and, providing a protective cap adapted to snap on the nozzle end of the caulking tube. The open-ended section of the flange ring is positioned in the piston end of the tube with the flange overlying the end of the tube. The cap is axially aligned with the tube, and a force is applied to move the tube onto the anvil member. The force is sufficient to snap the cap onto the tube. Thereafter, the tube is rotated and the flange portion is deformed into a bead engaging the end of the tube. The specification also discloses apparatus specifically suited for carrying out the above sequence of steps.
