ABSTRACT:
A machine and method for shaping a workpiece into a cylindrical tube includes a mandrel, a forming roll, a guide roll, and a continuous forming belt extending partially around the mandrel and partially around the forming roll and guide roll. The workpiece is inserted between the belt and the mandrel at an entry opening. An actuator device causes the mandrel to simultaneously tighten the belt and squeeze the workpiece between the mandrel and the forming roll during the forming operation.
