Abstract
A turning roll system for rotating a cylindrical workpiece about a workpiece axis comprises a pair of idler rollers cooperating with a pair of drive rollers to support the workpiece. To oppose axial drift of the workpiece, each idler roller is rotatably journalled on a respective idler axle such that the axis of rotation of the idler roller is oriented obliquely relative to a pivot axis of the idler axle. The idler axles may be pivoted about their respective pivot axes to adjust the orientation of the idler roller axes relative to the workpiece to introduce an axially directed force component acting on the workpiece to counter axial drift. Pivoting of the idler axles may be automatically controlled based on a signal generated by a drift sensor arranged to detect axial drift of the workpiece.
