Abstract
Successive blocks of corrugated sheets are divided from a large vertical stack by a combination of a horizontally movable pusher plate and a guiding ramp that lifts the front edge of each block of sheets upwardly and onto a receiving conveyor surface. The ramp is a hybrid that includes a powered cylindrical roller and an adjacent yieldably biased upright plate that is moved to an inclined position in response to initial movement of a block of sheets.
