Abstract
The device comprises a housing mounted on the draw bench contg. the drawing die, on both sides of which are guides for the stock. The plant between the guides submits the stock to a changing force which deflects it. The plant has a rotor whose axis corresponds to the drawing axis and a body contg. the drawing die is mounted in the rotor eccentrically on bearings. The guides act as supports for the bending action transmitted to the stock during drawing. The device produces excellent levels of straighteners without the necessity for intermediate operations, avoids damage to the stock, and produces a finished prod. when drawing is the last operation.
