Abstract: A joint module for forming a joint section from a tube that is formed at an operational speed by a roll forming machine may include a carriage positioned proximate the back end of the roll forming machine and configured to move in a longitudinal direction relative to the back end. A pleat die assembly may be mounted on the carriage and configured to repeatedly engage the tube to form a series of pleats thereby bending the tube to form the joint section, and a crimp die assembly may be mounted on the carriage and configured to engage the tube to crimp an end of the joint section and to sever the end of the joint section from the tube. The carriage may move relative to the frame while the tube is engaged with at least one of the crimp die assembly and the pleat die assembly.

Abstract: A roll forming machine for continuously forming a sheet into a joint section of a tube may include a plurality of roller stations arranged longitudinally on a frame and configured to bend the sheet to form the tube, and a carriage slidably secured to the frame. A pleat die assembly may be mounted on the carriage and can be configured to repeatedly engage the tube to form a series of pleats thereby bending the tube to form the joint section. A crimp die assembly may be mounted on the carriage and can be configured to engage the tube to crimp an end of the joint section and sever the end of the joint section from the tube. The carriage may be configured to be selectively moved relative to the frame while the tube is engaged with at least one of the crimp die assembly and the pleat die assembly.
