Abstract

A stretch rolling method and a stretch rolling unit can roll out any gripping ends and uses the narrowest possible installation space. In the stretch rolling method, a workpiece is successively fed to at least two passes of a stretch rolling unit of a gripping device, wherein the workpiece is rotated by 180° about an axis of rotation lying perpendicular to the main direction of extent of the workpiece between the first pass of the two passes and the second pass of the two passes.
