About this machine

This Stahl KC 78 4-KZ is a used folding machine — sometimes referred to as a paper folder or buckle folder — offered for sale from Germany. Folding machines of this type are used in the printing and finishing industries to automatically fold printed sheets into signatures, booklets, brochures, and other multi-page formats. Stahl is a well-established German manufacturer with a long history of producing high-quality folding and finishing equipment for commercial and industrial print operations.

This particular machine is configured as a 16-page cross fold system and was built in 1988, carrying serial number 36526/. It features a maximum working width of 780 mm, making it suitable for handling a broad range of sheet sizes. Sheet feeding is handled by a round pile feeder, which allows for continuous, high-volume feeding from a circular stack without interrupting production.

The folding configuration is arranged across two stations. The first folding unit is equipped with four buckle pockets, which create folds by forcing the sheet against a stop and buckling it between rollers — a method well suited to parallel and combination fold patterns. The second folding unit carries three knife folds, which use a descending blade to push the sheet between rollers for more precise or heavy-stock folding; this unit can be set for either left or right delivery depending on workflow requirements. Together, the two stations give the machine its 16-page cross fold capability.

Delivery is handled by a Stahl SAK stream delivery unit, which overlaps the folded products in a shingled stream for neat, controlled output. Front-mounted and rear-mounted slitter shafts are included, allowing sheets to be slit longitudinally before or after folding as required. The machine comes complete with a compressor and the original operator manuals.
