Apparatus for and method of winding-up a metal strip, and plant for producing a metal strip windable into a coil

摘要

An apparatus (1) for winding-up a metal strip (2) into a coil (3), includes a clamping pair (22) formed of a deflection roller (23) and a pressure roller (24) and located in front of the coil (3) in a material flow direction (10) so that the strip (2) is retained under tensional stress with respect to the coil (3) and is so bendable that the strip (2), which is provided with a corresponding pre-bend, is firmly wound into a coil (3). The apparatus further includes a first bending roller (35) pressable against the deflection roller (23), and arranged in front of the clamping pair (22) in the material flow direction (10), and a further roller (36) adjustable relative to the deflection roller (23) and arranged behind the clamping pair (22) in the material flow direction (10), with the pressure roller (24) and both bending rollers (35, 36) being so displaceable relative to the deflection roller (23) that an end region (45) of the strip (2) is additionally curved to form the pre-bend dependent on an end diameter (48) of the coil (3).
