Abstract: A cross-fold system for use in combination with a device for folding sheet material and includes a rigid guide structure having a stationary reaction surface for supporting and guiding folded sheet material along a feed path between a sheet feed mechanism and a tensioning mechanism. Furthermore, the cross-fold system includes a paper break assembly disposed between the sheet feed mechanism and the tensioning mechanism. The paper break assembly, furthermore, includes an abrasion bar disposed transversely of the feed path and in opposed relation to the rigid guide. Moreover, the paper break assembly is 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 permits the sheet material to pass to the tensioning mechanism without engaging the sheet material.

Abstract: A sheet stacking apparatus for storing a plurality of sheets is disclosed having a storage chamber having a first transverse dimension, a platform located within the storage chamber for storing a plurality of sheets in a substantially vertical stack thereon, a feeder for feeding a top sheet from the stack, and means for moving the platform upwards to hold the stack in operative contact with the feeder, wherein the platform comprises a support portion having a second transverse dimension which is less than the first transverse dimension, for allowing sheets stacked on the platform to droop below the support portion in at least one overhanging region.
