PLANNING MACHINE Russian patent published in 2009 - IPC B21D1/02 

FIELD: technological processes, metal working.

SUBSTANCE: invention is related to the field of metal forming, namely, to planning of rolled metal in mangle machines of multiple alternate bending. Two rows of straightening rollers are installed in staggered order, lower row of which is installed stationary on bed plate. All rollers are arranged as driving, and upper row is installed in fixed cross beams. Each upper straightening roller is mounted on bearings on two sliding members, each of which has the possibility of reciprocal motion in plane, which is perpendicular to direction of metal motion, and is connected to drive of its motion, for instance, by means of hydraulic cylinder installed on cross beam. Besides, there are more rollers in upper row then in the lower roller by one piece.

EFFECT: expansion of technological resources.
