Abstract
A gapless order change in a continuous running corrugated paperboard web, created by using a partial transverse web sever upstream of the web selector device, utilizes selector fork orientation and operation that allows a redirected web portion to be diverted from one slider table to the other with no gap at the transverse slit. The improved apparatus is particularly effective in providing web transition at order change from the lower slider table to the upper slider table where the total width of the output web portions going to the upper level is increased and requires an upward diversion of a redirected web portion.
