Abstract

The invention relates to a method for tension levelling a cold-rolled strip, whereby the strip passes through a series of break rolls and a series of traction rolls and in the course of its extension is subjected to traction between the two series of rolls. The strip is bent under traction in a series of high-traction rolls, located between the brake roll and the traction roll series, in order to increase the degree of levelling. To achieve this, the series of high-traction rolls between the brake and the traction rolls has at least two traction rolls for generating the strip traction and bending operation.
