Patent ID: 8162811

Claim:
A cross-fold system for use in combination with a device for folding sheet material, comprising: a sheet feed mechanism operative to feed a folded sheet material; a rigid guide having a stationary reaction surface for supporting and guiding the folded sheet material along a feed path between the sheet feed mechanism and a tensioning mechanism; and a paper break assembly disposed between the sheet feed mechanism and the tensioning mechanism and including an abrasion bar disposed transversely of the feed path and in opposed relation to the rigid guide, the paper break assembly, furthermore, being repositionable from an active position to an inactive position such that, in the active position, the abrasion bar pressingly engages the sheet material against the stationary reaction surface of the guide assembly, and, in the inactive position, the abrasion bar is inoperative to permit the sheet material to pass to the tensioning mechanism without engaging the sheet material; the tensioning mechanism operative to pull the folded sheet material across the abrasion bar to yield the adhesive bond between reinforcing fibers of the sheet material when the paper break assembly is in is active position; whereby yielding the adhesive bond between the reinforcing fibers facilitates a cross-fold of the folded sheet material.
