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, this floating baffle can provide plural mode functions by providing 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. Also disclosed is a spring or other flotation and mounting system for automatically maintaining a baffle spaced within a few millimeters 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 the spacing is maintained by the scuffer position.
