Abstract: The invention relates to a method for cutting a sheet metal blank from a sheet metal strip (1) continuously conveyed in a transport direction (T), by means of at least one laser cutting device (3), having the following steps: providing a laser cutting device (3) with at least one laser cutting head (5) which has a cutting nozzle (7) and which can be moved along a cutting path (S1, S2, S1?, S2?) specified so as to correspond to the geometry of the sheet metal blank by means of a controller (6), incrementally measuring the distance between the cutting nozzle (7) and the surface of the sheet metal strip (1) at at least one radially outer position (P1, P2) relative to the cutting nozzle (7) by means of a first distance measuring device (8), controlling the movement of the laser cutting head such that the first distance measuring device (8, 9) constantly remains overlapping the sheet metal strip (1), into a second position, in which the cutting nozzle is overlapping the sheet metal strip (1), wherein the height

Abstract: In a method for setting bending of at least one straightening roller in a roller straightening machine, the straightening roller is supported by a plurality of supporting roller devices arranged beside one another in the axial direction, wherein each supporting roller device can be adjusted by an actuating device such that stresses are produced in the straightening roller. To control the actuating device, a control system is provided, by which the adjustment of the supporting roller device can be set manually. Limiting values (vMA, vMI) with respect to the stresses produced in the straightening roller are stored in the control system. In the event of adjustment of one of the supporting roller devices, maxima (MA) and minima (MI) of the stresses produced in the straightening roller are calculated and it is checked whether the maxima (MA) and minima (MI) lie within the limiting values (vMA, vMI).

Abstract: The invention relates to a method for correcting a predetermined cutting path for cutting a metal blank from a metal strip continuously transported in a transport direction x with the following steps: Simultaneously determining a first x coordinate x1 and a first y coordinate y1 of a point on a surface of the metal strip with respect to an x and a y reference; Determining a second coordinate y2 of the point with respect to the y reference at precisely the time when the metal strip has been moved in the transport direction x by a predetermined first distance dx1 with respect to the first x coordinate x1; Determining a first y correction value Ky1 by taking the difference between the first y coordinate y1 and the second y coordinate y2; and Using the first y correction value Ky1 to correct the cutting path coordinates describing the predetermined cutting path.
