Unwinding and cutting process

An unwinding and cutting process comprises: unwinding a coil bands, straightening, cutting the front end, moving in a knotting device, moving from the knotting device, then cleaning the surface of the coil and directing bands; Conveying the coil bands on a pinch roller to perform and -zuschneiden laser cutting, two static laser cutting heads are used for cutting the coil strip during the laser cutting and the cut-away waste from the cutting area falls down and is conveyed to the outside; and after the completion of cutting, finally, cutting the obtained sheets from one another, receiving it by a recording device, and conveying these onto a conveyor belt to a Aufgreif- and stacking area for stacking the sheets. An unwinding and cutting process of the present invention uses a static laser cutting, the operating rate and the yield by means of a cooperative operation of two laser cutting heads can effectively improve, replaces the Formzuschneideverfahren and has no associated therewith form and maintenance costs, does not require any form of stack space, has a flexible mode of operation on, simplifies the layout of the production line and is easy to handle.
