Abstract

Rolling stock is transported in a transporting device from a front roll stand to a rear roll stand. Between the roll stands, the rolling stock carries out an oscillation transverse to the transporting direction. At least one characteristic property, amplitude or frequency, of the oscillation is determined quantitatively and, from this determination, a tension or compression, existing in the rolling stock between the roll stands is determined. One of the roll stands is readjusted in such a manner, that a desired tension is built up in the rolling stock between the roll stands.
