Abstract (en)
[origin: EP0906797A1] The strip material is moved alternating over and under at least two stretch-levelling working rollers (7,8), between a cooling zone and a coiler. The working rollers are offset relative to each other, to deflect the strip on every roller. The rollers are of two types, being cylindrical or with a negative or positive roller crown. The rollers are self-propelled, and the stretch-levelling zone is water cooled.
