The Collibri Backgluing Machine enables sewn book blocks to be glued off and lined with ultimate versatility – a wide range of formats and gluing methods is available – all with exceptional book quality.

The Collibri offers impressive advantages

• Book block thickness from 1/8" to 3 1/8"
• Max. spine length 20"
• Short changeover times
• Various gluing methods
• Modular design – for one-shot or two-shot glue application

Shortest changeover times
In line with current market trends the Collibri is positioned for economical production of large as well as small runs. The result is a highly automated machine with extremely short set-up times. To start a new job the machine operator simply enters the block size on the control panel and within less than one minute the machine has completed all necessary production settings.

Various gluing methods
Emulsion cold glue, hotmelt, or two-shot can be interchangeably used on the Collibri. The glue level is controlled automatically by a sensor, while uniform glue consistency is maintained by a pneumatic glue pump. These two elements ensure consistent glue application for all glue types. In emulsion cold glue and combined two-shot processes the moisture of the applied glue is extracted in a newly developed infrared section with infrared radiators and an air-circulating blower.

Reliable lining station
The liners are fed from a wide roll that is mounted transversely to the book block. Compared to machines with longitudinal liner rolls much fewer roll changes are needed, which considerably shortens the set-up time and simplifies the inventory control for liner rolls. The liner-pressing station integrated in the Collibri ensures perfect book blocks.
