The Kolbus ZU 801 is a used book binding machine — specifically a signature gathering machine, sometimes referred to as a collating machine — designed to assemble folded printed sections in the correct sequence ahead of binding. Kolbus is a well-established German manufacturer with a long history of producing equipment for the bookbinding and print-finishing industries, supplying machinery to commercial printers, book manufacturers, and binderies worldwide.
This machine features 20 gathering stations, allowing it to collate up to 20 signatures in a single pass. It operates at a speed of 6,000 cycles per hour, making it well suited to medium-to-high volume production environments. The format range is broad, accommodating a maximum sheet size of 290 × 420 × 65 mm and a minimum of 105 × 105 × 3 mm, which gives it flexibility across a wide variety of book formats and section thicknesses. The machine is equipped with a criss-cross delivery system, which staggers the gathered book blocks as they are discharged, helping to prevent damage and facilitating easier downstream handling.
The machine carries manufacturer number 391 and dates from 1999. It is offered in used condition and is currently located in Germany.
