ABSTRACT:
A signature feeder with a stack-supporting conveyor for moving a stack of signatures to a dispensing location. A pick-up conveyor engages the stack and positions the signatures in an imbricated stream and a guide member directs them to a deposit location where the signatures are again placed into a stack from whence they are dispensed to a feeder mechanism. Sensors are disposed at the forward face of the stack and also at the deposit location, and the sensors are connected to electric motors which in turn drive either the stack-supporting conveyor or the pick-up conveyor.
