ABSTRACT:
A drum is mounted to rotate about its drum axis. A pair of elongated, complementary guides are proximate to and extend along the axial length of the drum. The guides are sized and spaced to allow a workpiece to span the guides and roll upon them. A driver is mounted alongside the guides for rolling the workpiece on them. These guides are positioned between the drive means and the drum. The workpiece is positionable between the driver and the guides to protrude beyond the guides and reach the drum.
