This Theisen & Bonitz Sprint 315 VP is a used book binder — sometimes referred to as a saddle stitcher or booklet maker — dating from 1999 and currently located in Germany. Book binders of this type are used in the print finishing industry to collate, stitch, fold, and trim signatures or sheets into finished booklets, brochures, catalogues, and similar bound products. Theisen & Bonitz is a well-regarded German manufacturer of print finishing and binding equipment, known particularly for its gathering and stitching lines serving commercial printers, publishers, and trade binderies.
The system as listed comprises two integrated units: a gathering machine, the Sprint 315 VP, and a combined stapling, folding, and cutting unit designated the QSM 303. Together they form a complete inline saddle-stitching line capable of collating, stitching, folding, and front-trimming in a single pass.
The Sprint 315 VP gathering machine is equipped with 15 feeders, allowing up to 15 individual sections or sheets to be collated in a single cycle. It operates at an output of 3,100 cycles per hour and accommodates a format range from a minimum of 6.5 × 10 cm up to a maximum of 35 × 50 cm, giving it considerable flexibility across a wide variety of product sizes. The stacking height reaches a maximum of 300 mm. The gathering unit includes double-sheet and missing-sheet control, which monitors each feeder to detect and reject faulty collations, helping to maintain consistent output quality. The machine runs under a PLC control system, providing automated and repeatable process management.
The QSM 303 stitching, folding, and cutting unit matches the gathering machine's output rate of 3,100 cycles per hour. It features a press folding device with motorised adjustment, allowing fold pressure and positioning to be set precisely without manual mechanical intervention. Stitching is performed by two Hohner Universal 48/5S stitching heads, a well-established head model used widely in saddle-stitching applications. The unit is also fitted with a display counter and a kicker, the latter being a standard device used to eject and stack finished booklets at the delivery end of the line.
