Abstract
A gapless order change in a continuous running corrugated web is provided by utilizing a partial web sever extending transversely across the web upstream of a web selector device. The partial web sever allows the output web selector device to be readjusted downstream of the slitter-scorer to redirect the output webs between upper and lower cut-off knives as required. The partial web sever allows the order change to be effected with a continuous unbroken web containing the outs for the cut-off knife level handling the output web portions opposite the partial sever.
