ABSTRACT:
A signature collating machine having a plurality of sequentially situated signature supply stations whose common floor rises via an electronic sensor to maintain signature stacks at operable heights. Above each supply station is a suction delivery assembly, each of said assemblies having a suction port housing and a suction port extending therefrom for engagement with a signature. The machine further has traveling collector rods which sequentially gather signatures engaged with respective suction ports. An actuator is provided which causes upward movement of a suction delivery assembly, and consequent positioning of a signature for subsequent collating, upon suction port engagement with a signature. Circuitry is provided which causes collector rod travel to cease if any suction port ahead of a collector rod is not engaged with a signature, thus eliminating accidental non-inclusion of a signature. Upon collector rod engagement and lateral pressure within the fold of a signature, suction delivery to the suction port automatically discontinues and the signature is released therefrom to be then maintained on the collector rod. A similar manually-operable collating machine is also disclosed.
