Abstract
A movable platform supports a stack of sheets, with at least a portion of the stack being in a predetermined feed zone where feeding apparatus engages and feeds the sheets, one-at-a-time, from the feed zone into processing machinery. Biasing means continuously urge the platform toward the feed zone and are responsive to a controller for advancing additional sheets of the stack into the feed zone as the sheets are fed therefrom. A sensor is responsive to removal of sheets from the feed zone to energize the controller for enabling the biasing means to advance the table when sheets are not present in the feed zone and to deenergize the controller for disabling the biasing means and terminating movement of the platform when sheets are present in the feed zone.
