Abstract

An improved sheet separator/feeder 1 for feeding individual sheets 2 seriatim from the bottom of a stack of the sheets with a reduced wear rate and more reliable feeding of intermixed varieties of original document sheets. As particularly shown in the Figure 2 rear view (approximately twice the scale of Figure 11, a wider (e.g., almost 2 inch) frictional bottom feed belt 3 and floating gate 4 are utilized. The floating gate 4 is conventionally spring biased toward (against) the separation nip with the belt 3, which is supported there by an underlying idler roller 5. Conventional spring loaded normal force (stack lead edge holddown) means 6 are shown in Figure 1, (but not in Figure 2).

FLOATING GATE SHEET SEPARATOR/FEEDER WITH OUTRIGGERS (Cont'd)

An improved sheet separator/feeder 1 for feeding individual sheets 2 seriatim from the bottom of a stack of the sheets with a reduced wear rate and more reliable feeding of intermixed varieties of original document sheets. As particularly shown in the Figure 2 rear view (approximately twice the scale of Figure 11, a wider (e.g., almost 2 inch) frictional bottom feed belt 3 and floating gate 4 are utilized. The floating gate 4 is conventionally spring biased toward (against) the separation nip with the belt 3, which is supported there by an underlying idler roller 5. Conventional spring loaded normal force (stack lead edge holddown) means 6 are shown in Figure 1, (but not in Figure 2).

The floating gate 4 here has integral "outriggers" 7 on both sides of the regular stack engaging face 8 but off the belt 3. These outriggers 7 have faces engaging the stack slightly upstream of the main face 8 (but at the same angle to the face of the stack) for initial stack registration and some initial stack shingling, and for limiting the number of sheet edges arriving at the main gate face 8 at one time for final...
