Method of irradiating running strip with energy beams

摘要

A method of irradiating a continuously-running strip with energy beams. Scanning the width of continuously-running strip positions energy-beam irradiating devices along the width of the strip. Allocation of scanning regions along the width of the strip corresponding to respective energy-beam irradiating devices is determined. When an edge deviation or strip wind is detected by a strip-edge detector upstream of the energy-beam irradiating devices, the strip regions to be scanned are adjusted. If the amount of strip wind exceeds the limits of the scannable energy-beam irradiating devices, neighboring irradiating devices are re-oriented, all in response to upstream strip wind detection.
