Abstract
A system is configured for forming a flange at an end of a tube. The system includes a collar configured to receive the tube. A first roller engages the collar and a second roller is configured to cooperate with the first roller to rotate the collar and the tube. A rotatable cam is disposed about the second roller and includes a cam surface configured to bend the end of the tube to thereby form the flange. The collar may be configured to restrict axial movement of the tube relative to the collar. Additionally or alternatively, the collar may be configured to restrict rotational movement of the tube relative to the collar.
