Patent

CA 2380150

A method and apparatus for reducing burden in retrieving sheets of material from the bottom of a substantially vertical stack of sheets in a sheet feeder. The apparatus comprises a first convex surface at the bottom half of the stack protruding into one side of the stack for pushing the sheets toward the other side, and a second convex surface on the second side below the first convex surface for pushing the sheets toward the first side. The first and second convex surfaces each provide a counteracting force resisting the downward movement of the stack, and these countering forces have upward vertical components partially countering the downward vertical force due to the weight of the stack.
