ABSTRACT:
A bending apparatus for rod-shaped and tubular workpieces, includes a rotatable bending mandrel with a bending groove is provided with a wrinkle smoothener, which immediately precedes the bending mandrel, and two sliding jaws. In order to change the bending direction around the bending mandrel, the sliding jaws can be moved to the other side thereof. In doing so, the sliding jaw on the side of the bending mandrel is arranged freely rotatable on a support axis, which extends parallel to the axis of rotation of the bending mandrel and whose position relative to the bending mandrel can be shifted parallel to the feeding direction of the workpiece. The sliding jaw is provided such that the end of its forming groove facing towards the bending mandrel can be placed in contact with the bending groove by shifting the support axis and, thus, its forming groove tangentially joins said groove.
