ABSTRACT:
A system is provided for synchronizing the end of order cutoff for a plunge slit order change on a corrugator that minimizes scrap and cuts the end order sheets to a length and width such that jam-ups at order change are eliminated. The system detects a transverse edge discontinuity immediately prior to end of order cutoff and, in conjunction with a prior calculation comparing sheet lengths and order end positions between upper and lower webs, positions an upstream transverse partial web slit at an optimum order end position such that the entire web is ultimately cut on the partial sever at an optimum position for scrap minimization and scrap sheet size and shape.
