About this machine

This Heidelberg Stitchmaster S is a used book binder — sometimes referred to as a saddle stitcher or saddle binder — a type of machine used to collate, stitch, and trim gathered signatures or sheets into finished booklets, brochures, and similar saddle-stitched publications. Heidelberg is one of the world's most recognised names in print finishing and pressroom equipment, supplying high-quality machinery to commercial printers, book manufacturers, and finishing houses globally. This example was manufactured in 2007 and is currently located in Germany.

The machine is equipped with a large-screen display for operator control and monitoring. The collating section comprises eight chain undercarriages fitted with sword-type feeders (KUS), four standing feeders (DVU 450) with clocked blowing air, two horizontal feeders (DHU 450) with intermittent blowing air, and one card feeder (CHU 450) fitted with creasing segments. Blowing air is also provided for empty field detection and between the investing stations, supporting reliable sheet separation and feeding throughout the collating chain.

The stitching station includes one stapler unit (HS 450) with a stitching wire transport device and a large spool carrier for wire. Four conventional stitching heads (45-N14-24) and four ring eyelet stitching heads (Hohner 50-L6) are fitted, giving the machine flexibility for both standard and eyelet-stitched products. A quick-change device for the stitching heads facilitates fast job changeovers, and staple control from below (HKKU) is included for quality monitoring of the stitching result. Width control is also present.

The trimming and cutting section is built around a trimmer (TR 450) with a trio cutting device for three-knife trimming of the finished booklets. A universal small-format transport device covering a range of 64×120 mm is fitted, along with an air device for two punching knives and a dedicated centre cutting device. Cut control monitors the trimming process, and an ULMW transition marking table with an exclusion switch is included for rejecting defective copies.

On the delivery side, the machine features a missing-sheet delivery with interval function, a servo ejector, and a stacker (HD automatic). The delivery belt measures 832 mm in width, and a tunnel of the same 832 mm width is fitted with a telescopic guide (Telem). A mobile take-off table (MT 1200, 1200 mm) and a chip conveyor belt for waste removal complete the outfeed arrangement.
