An apparatus for securing an end cap including an end cap flange to a shell including a shell flange by forming a lip portion including the end cap flange and the shell flange into a lock seam portion in which the end cap flange and the shell flange are engaged with each other. The apparatus includes an elongate tool element rotatable about the central axis, for receiving the end cap thereon. The apparatus also includes a number of roller subassemblies for forming the lip portion into the lock seam portion. Each roller subassembly includes a forming roller engageable with the lip portion while the tool element rotates. Each roller subassembly also includes an arm on which the forming roller thereof is rotatably mounted, and a support mechanism for positioning the arm to engage the forming roller with the lip portion.

Apparatus and method for securing an end cap to a shell

A tube loading assembly for use in loading a tube on a flexible mandrel of a tube bending machine; said assembly comprising mandrel receiving means for receiving said mandrel; mandrel alignment means for aligning said received mandrel to be co-axial with said tube; and means for feeding said tube on said co-axially aligned mandrel. The assembly is of use with tubes to be bent for use in automotive exhaust systems, heat exchangers and aircraft hydraulic systems, and provides for improved automatic loading speeds.
