Application 10/000,843
Claim 1 under appeal reads as follows:
1. A multi-high roll stand comprising:
several driven support rolls;
several working rolls frictionally driven by the support rolls,
the working rolls being movable in a substantially horizontal
direction;
an adjusting system connected to the working rolls;
wherein the working rolls form a roll gap defining a thickness
of rolling stock guided between the working rolls in a rolling
direction;
wherein the adjusting system moves the working rolls in the
horizontal direction for adjusting a gap width of the rolling gap such
that longitudinal axes of the working rolls are moved parallel to
longitudinal axes of the support rolls in the rolling direction and the
working rolls roll on surfaces of the support rolls, respectively, the
adjusting system including a respective adjusting device for each of
the working rolls, the adjusting devices being connected to the ends of
the working rolls, the adjusting devices of the working rolls being
configured to adjust a position of the working rolls in the rolling
direction; and a common control device connected to the adjusting
devices,
wherein the common control device provides a set value for
each one of the adjusting devices as a function of a measured value of
a thickness of the rolling stock and as a function of the preset value
for the thickness of the rolling stock.
