METAL STRIP ROLL MILL Russian patent published in 2011 - IPC B21B39/08 

FIELD: process engineering.

SUBSTANCE: invention relates to metal forming, namely, to metal strip roll mill equipment. Proposed roll mil comprises at least one stand 2, front strip reel 3 and rear strip reel 4. S-shaped roll unit 5, 6 is mounted between rear strip reel 3 and stand 2 and/or between stand 2 and rear strip reel 4. Said S-shapes roll unit 5, 6 comprises two rolls 7, 8, 9, 10 that lead strip 1 in S-like manner. First roll 7, 8 of said S-shaped roll unit 5, 6 is stationary while second roll 8, 10 moves relative to the first one. Second roll 8, 10 is mounted on rotary lever 11 with its one side seating on stationary axle 12. Stationary axle 12 corresponds to rotational axis of first roller 7, 9. Linear actuator is arranged on rotary lever 11 at turn point 13 between rotational axes of both rolls 7, 9, 8, 10. Said linear actuator 14 and S-shaped roll unit 5, 6 can be adjusted to compensate mass flow without varying drawing force in non-stationary rolling.

EFFECT: better regulation of strip width.
