Claims19
A method of stretch-bend leveling metal strip, the method comprising the steps of:
- bending the metal strip alternately around a plurality of stretching rollers under a tensile stress, and increasing the stretching rate in a downstream strip-travel direction,
- providing one or more stretching rollers with a plastic jacket.
An apparatus for stretch-bend leveling metal strip the apparatus comprising:
- an inlet tension roller set for establishing strip tension,
- an outlet tension roller set for releasing the strip tension,
- a plurality of stretching rollers between the inlet tension roller set and the outlet tension roller set, the to strip being bent in alternation around the stretching rollers with an increase in the stretching rate,
- a plastic jacket on one or more stretching rollers.
