About this machine

This Stahl KC 78-4-KZ is a used folding machine — sometimes referred to as a paper folder or buckle folder — designed to automatically fold printed sheets into multi-page signatures. Folding machines of this type are a core piece of finishing equipment in commercial printing, publishing, and bookbinding operations, where precise, repeatable folds are required at production volumes. Stahl is a well-established German manufacturer with a long history of producing paper-folding and finishing machinery for the graphic arts and print industries, and their equipment is widely regarded as a reliable workhorse in professional print environments.

This particular machine is configured as a 16-page cross-fold unit and is equipped with a round pile feeder, which automatically feeds pre-stacked sheets into the folding sequence. The working width reaches a maximum of 780 mm, accommodating a broad range of sheet sizes suited to standard commercial print formats.

The folding system is arranged across two stations. The first station carries four buckle pockets, which use air pressure and mechanical stops to initiate and control the initial fold sequence. The second station is fitted with three knife folds and offers the flexibility of either left or right delivery, allowing the machine to be integrated into different production layouts depending on floor space and workflow requirements. A Stahl SAK stream delivery unit handles the output, presenting folded signatures in an overlapping shingled stream for easy collection and downstream handling.

Additional equipment included with the machine comprises front-mounted and rear-mounted slitter shafts, which allow longitudinal cutting or perforating of the sheet in line with the folding process — a useful capability for producing products such as mailers, inserts, or folded brochures requiring trimmed edges. A compressor is also included, as is a set of manuals. The machine dates from 1988, carries serial number 36526/, and is currently held in stock in Emskirchen, near Nuremberg, Germany, available for immediate collection.
