Abstract
A method for rolling a rolling material in a rolling mill comprising at least one roll stand. A gap height of a rolling gap arranged between working rolls of the roll stand is set to be smaller than an in-feed thickness of the rolling material before contact of the rolling material with the working rolls. At least one driven working roll of the roll stand is driven at a desired rotational speed once the rolling material has reached the rolling gap, and the driven working roll is operated at a feed-forward rotational speed deviating from the desired rotational speed, until the rolling material reaches the rolling gap.
