Method and device for producing a metal strip and reducing the risk of such a strip breaking.

摘要

Method for producing a metal strip, in which the risk of the strip breaking is reduced in a path in which the strip is conveyed under stress in the strip direction, in which method, in a prior feed path of the metal strip, any defects which are present in the edges of the strip are detected, and measures are then taken to reduce the consequences of these defects in terms of the risk of the strip breaking, in which method, at full strip velocity, a section of the edge which is of limited length and within which a defect has been detected is cut out by a driven shearing system which is moved towards and away from the strip transversely to the edge, the direction of which shearing system follows the path of the shearing cut, and the driven shearing parts, at the location of the shearing point, having a velocity component in the strip direction which corresponds to the strip velocity.
