ABSTRACT:
A sheet-metal strip coming hot from a rolling mill is subjected to alternate bending in opposite directions before being wound on a mandrel, preferably while still in a temperature range of about 600.degree. C to 800.degree. C in the case of steel. The bending is carried out by deflecting rollers which may be mounted upstream of a pair of reverse-feed rollers, acting as a strip brake, preceding the driven mandrel.
