Abstract
The invention pertains to a hopper loader apparatus for separating and forming an overlapping shingled stream of individual signatures of sheet materials from a vertically aligned, parallelepiped shaped stack of such signatures for subsequent handling operations. The hopper loader has a slippage resistant belt which engages a bottom edge of each signature and assists in preventing the signatures from slipping by keeping them upstanding. Preferably the slippage resistant belt has an array of projections extending upwardly from a belt surface which secures the signatures in place. This produces a smooth, regular, even signature stream. Individual signatures flow reliably, one-by-one off of the downward conveyor to another conveyor.
