ABSTRACT:
Apparatus for feeding objects to a transport mechanism and transport and delivery mechanisms for the objects, and, in particular, apparatus for feeding books to, transporting them through the cutting stations of and delivering them from a two-station, three-knife book trimmer. The feed mechanism includes a hopper for holding books, a prestripper for stripping a book from the hopper and moving it part way to the front knife cutting station and pushers, which continue to feed the book to the first cutting station, with means coordinating the prestrippers and pushers. The transport mechanism includes a plurality of displaceable, e.g. upper transport belts and a plurality of belts in opposition to the displaceable ones, e.g. lower transport belts, which clamp the book, respectively, from above and below. While clamping the book, the transport belts travel with it to the side knife cutting station, halt for side knife trimming, and then move the book beyond the second station to the delivery mechanism. The transport belts travel intermittently so as to be stationary when the book is delivered to the first station and to halt the object at the first and second stations. Displacement means, e.g. for the upper belts, separate the transport belts at the first station to permit a book to be fed between the upper and lower belts, and return means bring the belts together again to clamp the book. The delivery mechanism includes speeder belts for engaging the book from below and speeding it away from the transport belts.
