Claim Text:
1. A device for laterally guiding a rolled strip transported on a roller table in front of a coiling device, comprising: parallel first and second lateral guides provided on both sides of the rolled strip, the lateral guides being moveable toward each other or away from each other; independently adjustable adjusting means for moving the lateral guides; and a regulating device for damping periodic shifting of the rolled strip, the regulating device being supplied with input values, the input values representing forces acting during guidance of the rolled strip and positions of the lateral guides and/or the rolled strip, the regulating device being operative to regulate based on measured input values of positions of the lateral guides and forces the lateral guides exert on the rolled strip, wherein the regulating device includes a regulator which is operative to produce respective distance signals for the two lateral guides from the forces which the two lateral guides exert on the roll strip, wherein a force difference (F SAS −F SBS ) obtained from forces acting on the two lateral guides is supplied to the regulating device, which determines a differential position value from the force difference, wherein the regulating device further includes a first and a second position regulator arranged following the regulator for the two sides of the roll strip, wherein a sum of the differential position value produced by the regulator and a difference between the desired position value and the actual position value of the first lateral guide is supplied to the first position regulator, and a difference of the differential position value produced by the regulator and a difference between the desired position value and the actual position value of the second lateral guide is supplied to the second position regulator, whereby individual control of the adjusting means on both sides of the rolled strip is provided.
