ABSTRACT:
This apparatus removes individual sheets of paper or the like from a stack regardless of the thickness of each sheet. A sheet stack support is journaled in a housing in see-saw fashion. A first set of sheet separating rollers is arranged above the downstream end of the support as viewed in the direction of sheet movement. A spring urges the downstream end of the support upwardly and thus sheets on the support against the first set of rollers. A stop for the sheets is located adjacent to said downstream end of the support. A table is located substantially adjacent said downstream end and below a second set of sheet separating rollers. The table has a cut-out and a sheet separating gate slants through the cut-out below the second set of rollers. The gate is spring biased toward the second set of rollers. Further sets of rollers may be arranged downstream of the second set of rollers. These rollers are driven in such a manner that each downstream set runs faster than the next adjacent upstream set of rollers. The rollers, especially of the first and second set, are preferably of the free wheeling type, whereby a passing sheet may drive the rollers faster than the power drive for the respective rollers.
