Abstract
A rolling system, particularly a cold-rolling system for cold-rolling a metal strip (2): having at least one cold-rolling stand (1) an unwinding device (3) upstream of the cold-rolling stand (1), a unit (10) connected between the unwinding device (3) and the cold-rolling stand (1), including at least three rolls (6, 7, 8) each rotationally driven about a rotational axis (6A, 7A, 8A). Each roll (6, 7, 8) can be adjusted individually or together in the direction of the respective rotational axis (6A, 7A, 8A) and in a direction transverse to the rotational axis (6A, 7A, 8A) by a driving and adjusting device (11).
Claims23
A cold-rolling mill for cold-rolling of a metal strip, the mill comprising:
- at least one cold-rolling stand,
- a decoiler before the cold-rolling stand, and
- a unit in-line between the decoiler and the cold-rolling stand, the unit is comprised of at least three rollers, each roller is rotationally driven about a respective axis of rotation, wherein each of the rollers is configured to be repositioned, individually or jointly, in the direction of the respective axis of rotation and in a direction transverse to the axis of rotation;
- and
- a drive and positioning facility configured for positioning the rollers.
A method of cold-rolling of a metal strip with a rolling mill, the mill comprising at least one cold-rolling stand through which the metal strip is advanced, a decoiler before the cold-rolling stand, and a unit is configured for influencing the strip path and is located in-line between the decoiler and the cold-rolling stand, the unit is comprised of three rollers each driven about a respective axis of rotation,
- the method comprising:
- selectively positioning each roller during the rolling operation, by means of a drive and positioning facility, both in a direction of the respective axis of rotation of each roller and in a direction transverse to the axis of rotation of each roller.
