This Heidelberg Stitchmaster ST 450 is a saddle stitcher — sometimes referred to as a saddle stapler — a finishing machine used in print production to collate, stitch, and trim booklets, brochures, catalogues, and similar saddle-bound publications. Heidelberg is one of the most widely recognised names in the printing and finishing industry, producing equipment that serves commercial printers, publishers, and packaging operations worldwide.
Dating from 2007 and located in Germany, this used machine is configured as a complete, multi-station saddle stitching line built around the ST 450 platform. The feeding section comprises three horizontal feeders (DHU 450) and three vertical feeders (DVU 450), providing a total of six signature-feeding stations alongside a dedicated cover feeder (CHU 450). This mix of horizontal and vertical feed units allows the line to handle a range of paper types and signature formats across the gathering chain.
The stitching unit performs the stapling function at the spine, while finished booklets pass to a Three Knife Trimmer TR 450, which trims the head, foot, and face of each booklet in a single pass. The trimmer is additionally equipped with a centre knife device, enabling centre-cut or specialised trimming operations.
Delivery is handled by a Heidelberg Stacker Delivery CHA unit, supplemented by a RIMA stacker for neat, counted output stacking. The line also includes thickness control with automatic adjustment, allowing it to compensate for varying booklet thicknesses and maintain consistent quality throughout a run. Pump units are noted as part of the configuration. The combination of automatic thickness control, multi-station feeding, and integrated trimming makes this a well-equipped, production-capable saddle stitching line.
