Abstract
Device for winding a material web, particularly a metal strip, wherein a coil (1) is supported during the winding process by at least two support rollers (2, 3), wherein the support rollers (2, 3) can be jointly pivoted about a pivot axis (18) between a first, substantially horizontal, position and a second position, which is inclined relative to the horizontal position, by means of a pivoting device (11).
Claims13
A device for winding a metal strip, comprising:
- a coil on which the metal strip being wound is supported during a winding process;
- at least two support rollers on which the coil is supported during the winding process, the support rollers being pivotable jointly about a pivot axis, the pivot axis extending in a direction across a direction of a respective roller axis of each of the at least two support rollers, the at least two support rollers being pivotable jointly between a first, substantially horizontal orientation and a second orientation which is inclined with respect to the horizontal orientation;
- and
- a pivoting arrangement configured for pivoting the at least two support rollers such that respective pivot planes generated by respective pivoting movements of the axes of rotation of the at least two support rollers are vertical;
- wherein the pivoting arrangement includes a support device in which the at least two support rollers are mounted rotatably.

A method for winding a metal strip on a coil, the method comprising:
- supporting the coil on at least two separated rotatable support rollers, each roller of the at least two support rollers being rotatable about a respective roller axis;
- supporting the at least two support rollers, by a support device, to rotate and also supporting the at least two support rollers, by the support device, to pivot from a horizontal orientation to an orientation tilted from the horizontal orientation by pivoting the at least two support rollers around a pivot axis;
- winding the metal strip onto the coil supported on the at least two support rollers;
- determining that the metal strip incoming to the coil is offset in a direction along an axis of the coil from a desired axial position of the metal strip as it is incoming to the coil;
- and
- pivoting the at least two support rollers around the pivot axis that extends in a direction across the direction of each of the at least two support rollers,
- wherein the pivot axis of the at least two support rollers enables pivoting of the at least two support rollers between a substantially horizontal orientation and an inclined orientation which is inclined with respect to the horizontal, the orientation of the pivoting of the at least two support rollers is selected for causing return of the metal strip along the axis of the coil to a selected location of the coil;
- and the pivoting of the at least two support rollers is in respective pivot planes with a vertical rotation component in which the at least two support rollers pivot.
