the interior portion of the reservoir the reservoir has a movable floor 18 which is operated by appropriate means 20 to cause the floor and any sheets 22 on the floor to traverse as directed up and down within the center of the reservoir compartment in operation it is desired to keep the uppermost sheet 24 in as high a raised position in the compartment as possible without being pressed up against lip 16 means not shown may be provided to detect the actual position of the uppermost sheet as well as the approximate number of sheets remaining in the reservoir means may be provided such as airjet means to briefly ripple the stack of sheets from the general direction of arrow 26 in the preferred embodiment this airjet may be slightly downwardly directed into the sheet stack this causes the upper few sheets to have some air entrained between them and become somewhat if not completely separated from one another above the reservoir is a generally rectangular airjet plate 28 which has a generally c shaped sheet stop catch 30 at the rear portion thereof attached to the plate are rearward directed airjet 32 and forward directed airjet 34 in operation after the sheets are rippled and separated by airjet means from the direction of arrow 26 airjet 32 is activated to cause a flow of high velocity low static pressure.
