Abstract
The invention relates to a method for rolling up a metallic strip (1), in particular a steel strip, to a coil (2), the strip (1) being kept under longitudinal tension between a driver (3), consisting of at least one driver top roll (4) and at least one driver bottom roll (5), and a winding pin (6). The strip (1) is rolled up on the winding pin (6) to form the coil (2). In order to prevent the undesired opening of the wound coil in a simple manner, a bending moment (MB) is initiated in the strip, said bending moment acting perpendicular to the longitudinal direction of the strip (1) and causing a plastic deformation when a defined remaining length of the strip (1) is reached. The invention also relates to a device for rolling up a metallic strip.
