ABSTRACT:
A hopper loader apparatus and method for delivering signatures to a binding line, the hopper loader including a first conveyor having a horizontal entry portion and an arched exit portion. During operation of the hopper, the signatures are loaded onto the horizontal entry portion and moved toward the arched exit portion such that the signatures are fanned or deblocked as they travel over the arched exit portion. A second conveyor connected to the first conveyor receives signatures from the arched exit portion of the first conveyor and moves the signatures to the binding line. The arched exit portion is preferably less than 25% of the total length of the first conveyor. The horizontal portion of the first conveyor is located between 30 and 34 inches above a platform on which the hopper loader is standing to facilitate loading of the signatures onto the horizontal portion by an operator.
