Abstract

A signature supply apparatus moves signatures in an on-edge orientation to a signature feed apparatus which feeds the signatures one at a time. The signature supply apparatus includes a generally horizontal main section which supports a large number of signatures in an on-edge orientation with major side surfaces of the signatures upright. A hopper section is disposed at a higher level than the main section and supports on-edge signatures with the major side surfaces of the signatures upright and with a forwardmost signature positioned to be engaged by the signature feed apparatus. An inclined ramp section extends forwardly and upwardly from the main section to the hopper section. The ramp section supports the signatures on-edge in a thick shingled stream with major side surfaces of the signatures inclined forwardly and upwardly. The main, ramp and hopper sections of the improved signature supply apparatus support a continuous stream of on-edge signatures. A deflector assembly may be mounted on the main section of the signature supply apparatus to bow the signatures forwardly and separate major side surfaces of the signatures.
