ABSTRACT:
High speed sheet feeders receive blocks or bricks of paper sheets, cards or folders stacked edgewise on a downsloping supply ramp, and singulate these for edgewise feeding in rapid succession. The frontmost sheets ready for feeding are buckled and fanned at their upper edges, and their lower edges are arched forward to form a dimple or ridge-shaped pocket by an underlying central traction singulator. A pair of ganged or synchronized feed belts engage the frontmost sheet and propel it rapidly downward edgewise, and a slanting discharge belt receives and diverts the sheet at even higher speed between the discharge belt and a tractive pinch roller. A transfer assembly beneath the discharge belt may receive sheets from an adjacent feeder and interleave them upon command with sheets delivered by the discharge belt.
