ABSTRACT:
In a sheet stacking system with top sheet input registration assistance by a scuffer, or the like, and a cooperative floating buckle suppression baffle or ski over the stack, disclosed is a flotation and mounting system for automatically maintaining a baffle evenly spaced closely above the top of said stack, and automatically moved up as incoming sheets are added to the top of said stack, to allow incoming sheets to be easily fed thereunder with low friction. Preferably this spacing is maintained by the scuffer position. This floating baffle can also provide an integral sheet stopping lip extending downwardly from the top of the stack along one edge thereof to provide stack edge registration and to prevent registration edge climbing of incoming sheets.
