ABSTRACT:
A caliper-stitch and trim machine arranges a generally upright or generally vertical array of inserted signatures in the form of a book from a signature-arranging device on a portion of a generally triangular saddle. The caliper-stitch and trim machine includes a caliper means, eject means, a book actuated stitch control means, stitch device, and a trimming mechanism. The caliper-stitch and trim machine also includes portion of the saddle having two arms to form a split saddle.The split saddle moves the book past the caliper means, through the stitch device and into the trimming device. A rejection blade moves upward through the split in the saddle to eject caliper rejected signatures. After the caliper accepts a book of acceptable thickness, the book actuates the stitch control means to operate the stitcher device to deliver staples to bind the book. The stitched book is forwarded onto a carrier blade in the trimming mechanism in the same generally upright position to be face-trimmed by a horizontally movable knife. The carrier blade is then moved upwardly to deliver the book utilizing centrifugal and gravitational forces to the head and foot trim position for trimming and delivery.
