Abstract

The figure illustrates a two roll output stacking system for copy sheets produced by an automatic reproducing machine. The output rolls are typically placed adjacent the toner image fuser of the machine to deliver the individual copy sheets to a stacking tray 10. The system comprises a solid hard upper roll 12 with a plurality of thin roll rings 14 on its surface and a hard level roll 16 with a plurality of compressible foam tires 18 around it interspaced between the upper roll rings. Either roll may be positively driven with the other being driven by pressure contact with the driver roll. As the compressible foam tires travel through the upper and lower roll nip they deform to fill the space between the upper roll and the lower roll. This compression allows the roll nip integrity to be maintained thereby insuring a flame snuffing feature when placed adjacent a radiant fuser for example. As the foam tire exits the roll nip it exoands and drives the trail edge of the copy sheet off the roll so that it can fall into the catch tray when it reaches the point of vertical tangency with the foam tire. In addition, as the height of the copy sheet stack increases below the lower roll the foam tire continues to depress the stack to prevent a mis-stack.
