Abstract
Abstract In an apparatus for manipulating workpieces, especially billets of various sizes and shapes, a first frame includes a plurality of arms pivotably mounted for movement about a first axis and a second frame includes a plurality of arms pivotably mounted for movement about a second axis which is substantially parallel to and spaced from the first axis. The second frame is movable toward and away from the first frame so that workpieces of various sizes are accommodated. A supporting surface intermediate the first and second frame which may be raised or lowered is utilized for supporting slabs during turning thereof. At least two rollers are rotatably mounted on each frame for turning cylindrically-shaped workpieces.
