Abstract
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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
197 words
A method for forming a caulking cartridge of the type including a cylindrical body which holds the caulking material and having a nozzle end and a piston end, comprising the steps of: a. providing a generally cylindrical rotatable anvil member adapted to be closely received within the piston end of the caulking cartridge; b. providing a flange ring member including a cylindrical open-ended section having a flange extending radially outwardly from one end thereof; c. providing a protective cap adapted to snap on the nozzle end of the caulking tube; d. positioning the cylindrical open-ended section of the flange ring member in the piston end of the cartridge with the flange overlying the end edge of the body and axially aligning the cap with the cartridge; and, e. axially aligning the piston end of the cartridge with the anvil and applying sufficient axial force to move the anvil into the piston end of the cartridge to cause the cap to snap onto the nozzle end of the body and rotating the body and the anvil relative to a deforming means and deforming the flange with said means into a bead about the piston end of the cartridge.
