Strip material, especially metal coil, laser or arc plasma cutting method, and related continual cutting line

摘要

Process for the laser and/or plasma cutting of strips, particularly metal coils, and relative continuous cutting lines in which, upstream of the cutting line, there is a strip of metal in the form of a coil supported on a reel, positioned for unwinding, and in which the strip is initially straightened and then, using a transport system, is sent downstream towards a support bed, and is locally processed by the movement of an overhead focusing head which is part of the laser or plasma cutting unit. While cutting, the focusing head is mobile and moves exclusively along the axis which is transversal to the longitudinal forward travel axis of the strip. The strip is carried further downstream by an evacuation table, on which both the waste pieces and the finished pieces or details remain together, after which they are later separated.
