<p>An improved apparatus for feeding signatures from a saddle to a trimmer mechanism includes a transfer apparatus which moves each signature in turn from the saddle onto a conveyor assembly at a delivery station. The conveyor assembly includes a plurality of chains having pusher fingers which engage the trailing edges of the signatures. The pusher fingers move the signatures into the trimmer mechanism. The pusher fingers on the conveyor assembly are registered relative to a stop in the trimmer mechanism to at least partially register the signatures before they enter the trimmer mechanism. The transfer assembly, which moves the signatures from the saddle to the conveyor assembly, is effective to positively grip each signature in turn by applying a clamping force to opposite sides of the signature. These clamping forces are continuously applied to the signature from the time it leaves the saddle until it is deposited on the conveyor assembly where it is engaged by the pusher fingers. This prevents twisting and jamming of the signatures in the transfer assembly and/or at the entrance to the conveyor assembly.</p> |
