Abstract: A metal peeling machine for workpieces such as rods and tubes having a clamping carriage movably mounted on the machine bed. The carriage also receives a clamping arrangement which not only engages the workpiece but also is adapted to engage a workpiece guide sleeve, if and when the guide sleeve has to be moved for service purposes. The guide sleeve is provided with clamping means which are constructed to co-act with the aforementioned clamping arrangement on the carriage.

Abstract: A workpiece feed channel interposed between a metal peeling machine and straightener for elongated, rotating or non-rotating, metal workpieces. The channel includes a plurality of opposed pairs of driven profiled elements having workpiece receiving openings therebetween of a cross-sectional size approximately 1.5 to 10 times larger than the cross-sectional size of the workpieces carried therein. The workpieces are carried by and fed forwardly by the gravitational frictional engagement with the profiled elements. In one embodiment, the upper profile elements are raised to permit the release of the workpiece down inclined surfaces, rather than for the workpiece to continue on to the straightening machine.

Abstract: A method and an apparatus for carrying out the method for straightening sections of elongated workpieces such as bars and tubes in a bending, forging and/or straightening machine having at least one straightening roll which can be moved radially relative to the workpiece and at least a second roll for determining the straightening gap end face. During the initial and end phase of the straightening process the head and tail sections of the workpiece, respectively, are affected by a roll which moves in accordance with a preselected mathematical function or sequence.
