Zero waste order change system for a corrugator

摘要

A changeover system for a corrugator designed to halt the corrugator during the changeover to diminish paper loss. When the corrugator is halted, a traveling knife severs the combined webs adjacent the beginning of the steam table run. The slitter scorer and the cutoff are changed and the corrugator is restarted. The traveling knife which severs the combined webs may operate above the steam table or below the steam table; alternate forms may be used.
