Preforming

This section is designed in such a way that the least possible number of rolls have to be changed during size changes. The edge bending section serves to preset the strip edges for proper presentation to the welder. All roll movements are controlled by the computerized quicksetting system. In front of this section the hole punched during the coil joining process at the cross-welder is detected and this information is tracked and transmitted to the cut-off where the cross-weld is removed.
