Claim Text:
1. A method for adjusting rolls of a roll stand, wherein the roll stand comprises at least two cooperating work rolls, wherein one of the work rolls in the roll stand is mounted movably for adjusting a roll gap, and wherein the other work roll in the roll stand is mounted rotatably in a working position but is held fixedly, during rolling, in a direction perpendicular to a surface of in-process stock for defining a pass line, wherein the method for adjusting a height of the lower work roll before rolling comprises the steps of: (a) determining a position of a work roll before rolling using a measuring device at a reference point, wherein the work roll is mounted fixedly in the roll stand during rolling; (b) comparing the determined position value with a nominal value before rolling; and (c) adjusting the height before rolling of the work roll mounted fixedly in the roll stand and supported in a chock in a vertical direction by at least one adjusting element acting on a lower back-up roll as a function of the comparison value determined in step (b), so that the position of the work roll mounted fixedly in the roll stand for forming a pass line for the in-process stock matches the nominal value; and (d) beginning rolling.
