Abstract
A bottom level sheet feeding apparatus having a tray for receiving a stock of sheets, an endless belt conveyor having an upper run which extends into the tray, a lead surface superposed to the upper run of the conveyor downstream of the tray and inclined downwardly and terminating above the upper run to form a pinch point therewith, an idler roller positioned to support the upper run at the pinch point, and a retard strip superposed to the belt downstream of the lead surface. The lead surface has a relatively low coefficient of friction with the sheets to be conveyed, the upper run has a relatively high coefficient of friction with the sheets and the retard strip has a coefficient of friction with the sheets intermediate those of the lead surface and conveyor belt.
