Abstract

The invention relates to a method for the continuous stretching of metal strips, according to which the respective strip runs through a set of braking rollers and a set of tension rollers and, in the course of its stretching in the plastic range, is subjected between the two sets of rollers to a stretching tension which corresponds to the yield strength of the strip material. In a pair of tension-stretching rollers inserted between the set of braking rollers and the set of tension rollers, the strip is subjected only to the stretching tension required for stretching it in the plastic range. The transverse strain in the course of the plastic stretching is thereby minimised, with the result that central troughs or, in the case of longitudinal strip division, lateral edges of unequal length no longer occur. <IMAGE>
