The Kolbus BF 40T is a used book binder — a machine of the type also referred to as a casing-in machine — used in the production of hardcover books. It brings together a book block and its cover case in a single inline process, forming the bound, finished hardcover volume. Kolbus is a well-established German manufacturer with a long history of building bookbinding and book production machinery for the commercial print and publishing industries.
This machine is offered as a complete casing-in line rather than a standalone unit, incorporating several integrated stations. The line includes a Wohlenberg Model 44 three-knife trimmer, which trims the book block to its final dimensions on three sides simultaneously. Following trimming, the book block passes through a rounding station that shapes the spine to the characteristic curved profile of a hardcover book. A combined head-tailbanding and backlining station then applies gauze reinforcement and, where required, headbands and tailbands to the spine. A case feeding station presents the hardcover case ready for mating with the prepared book block, and a pressing unit — the Kolbus FE — together with heated joint-forming pressing stations, applies the pressure and heat needed to set the joints and complete the binding.
The line handles a format range from a minimum of 100 × 125 mm up to a maximum of 270 × 365 mm, covering a broad spectrum of standard hardcover book sizes. Book block thickness is accommodated between 6 mm and 70 mm, making the line suitable for everything from slim volumes to substantial reference works. Mechanical speed reaches up to 40 cycles per minute.
The machine carries serial number 558 and dates from 1977 according to the seller's notes. It is located in Emskirchen, near Nuremberg, Germany, is available immediately, and can be inspected and tested on site.
