Device and method for forming a transverse curvature on a metal strip emerging from an annealing furnace

摘要

The invention relates to a device (1) for forming a transverse curvature on a metal strip (3) emerging from an annealing furnace (2). In order to allow the formation of a transverse curvature on a metal strip (3) emerging from an annealing furnace (2) without impairing the surface quality of the metal strip (3), the invention proposes that the device (1) be at least one below a strip run of the strip Metal bands (3) arranged supporting nozzle assembly (6) which is adapted to a metal band (3) from below supporting gas cushion (7) between the metal strip (3) and the support nozzle assembly (6) to produce such that through the gas cushion (7 ) on the metal strip (3) the transverse curvature can be formed without contact.
