Abstract
In a sheet feeder device of the vacuum belt type, the vacuum belt moves in a pivotal manner between a generally horizontal sheet acquiring position, in which the lower face of the belt confronts the top surface of the top sheet, lying generally flat atop the underlying stack sheet; and a tilted position, in which the belt lifts the leading end of the acquired top sheet away from the underlying sheet, flexes it to insure its separation from the underlying sheet and delivers it endwise to a sheet receiving unit.
