Patent ID: 8616034

Claim:
A method for controlling the lateral guides of a metal strip ( 1 ), especially at the entrance or exit of rolling stands or in front of drive apparatus, wherein the lateral guides, one of which is located on each side of the metal strip ( 1 ), each comprises a straightedge ( 2 , 4 ) arranged laterally with respect to the metal strip ( 1 ), wherein the straightedges ( 2 , 4 ) are physically moveable independently of each other, and a first straightedge ( 2 ) is operated under position control and a second straightedge ( 4 ) is operated under force control, and wherein forces of the metal strip ( 1 ) acting on the first straightedge ( 2 ) and on the second straightedge ( 4 ) are measured, wherein the nominal force (S 2 ) for the second, force-controlled straightedge ( 4 ) is prespecified as a function of the measured force (K 1 ) on the first, position-controlled straightedge ( 2 ), wherein, in the case of an increasing force (K 1 ) on the first, position-controlled straightedge ( 2 ), the nominal force (S 2 ) for the second, force-controlled straightedge ( 4 ) is decreased and optionally, in the case of a decreasing force (K 1 ) on the first, position-controlled straightedge ( 2 ), the nominal force (S 2 ) for the second, force-controlled straightedge ( 4 ) is increased.
