The invention relates to a method for
cutting a sheet
metal blank (2) with a predetermined profile (K) from a sheet
metal strip (1) conveyed continuously in a conveying direction (x), said method comprising the following steps : at least one
laser cutting device is provided with at least one
laser cutting head (L, L1, L2, L3) movable in said conveying direction (x) and in a y direction perpendicular to said conveying direction, and also having control means for controlling movement of said
laser cutting head (L, L1, L2, L3) along a cutting path corresponding to said predetermined profile (K), by a first distance arranged upstream of said
laser cutting means The measuring device continuously measures the first distance (I1) between the first strip edge of the
metal sheet strip (1) and the fixed first measuring point in the y direction, and sends the measured first distance (I1) to the control device a distance value, using the predetermined cutting path and the measured first distance value, calculating a corrected cutting path by the control program of the control device, and moving the
laser cutting machine along the corrected cutting path heads (L, L1, L2, L3) to create slits in said sheet metal strip (1).
