The Heidelberg ST 100.1 is a saddle stitcher — sometimes referred to as a saddle stapler — a finishing machine used in print production to collate, stitch, and trim signatures into booklets, brochures, catalogues, and other saddle-bound publications. Heidelberg is one of the most widely recognised names in the printing industry, manufacturing a broad range of offset presses, prepress systems, and finishing equipment for commercial and industrial print operations worldwide.
This 1999 machine is configured as a complete inline production line. The gathering section comprises eight feeders in a DVA configuration, arranged as four double feeders, allowing multiple signatures to be collated in a single pass. A dedicated cover feeder unit (UFA) handles the outer cover, feeding and folding it around the gathered content before the assembly moves to the stitching station.
Stitching is carried out by two Hohner stitching heads mounted on the Heidelberg 100.1 stitching unit. Hohner is a well-regarded manufacturer of stitching heads used throughout the booklet-binding industry, and their inclusion here indicates a quality, production-grade stitching assembly. After stitching, the booklets pass through a three-knife trimmer, which squares the head, foot, and face in a single operation to produce a finished, trimmed booklet ready for delivery. Output is handled by a band delivery system.
The machine accommodates a minimum uncut sheet size of 89 × 120 mm and a maximum uncut sheet size of 305 × 349 mm. A compressor is included with the machine. The unit is located in Germany and is offered in used condition.
