C.P. Bourg is to unveil what it says is the first PUR perfect binder designed for automated in-line and off-line digital production of soft- and hard-cover products at the Graph Expo show in Chicago. The Bourg BB3202 PUR-C binds books in-line with a digital press or off-line with Bourg BSF Sheet Feeders.
Based on the company’s successful BB3002 perfect binder, the Bourg BB3202 PUR-C combines proven features and innovative automation with a highly efficient, compact and user-friendly PUR gluing system that is completely sealed and fully integrated with the binder’s operation. The technology includes an innovative autoloader and precision Nordson PUR dispensing. An automatic cleaning cycle makes it easy for the operator to purge old glue just once at start-up and quickly resume production.
The new binder produces perfect-bound volumes at a peak rate of 350 books per hour, depending on press speed, from digitally-printed content and covers. Final dimensions of books produced by the Bourg BB3202 PUR-C can range in size from 100 x 100 mm (3.94 x 3.94 in) up to a maximum 385 x 320 mm (15.15 x 12.6 in), and in thickness from 1 to 60 mm (0.04 to 2.36 in) – the largest of any in-line binder currently available, it said.
It automatically adapts to the thickness of each job to process each book most productively, and sets jogging, power milling and notching, gluing, scoring and suction cover-feeding under program control. The BB3202 PUR-C can also make 13 positive or negative high-quality creases utilising a knife-creasing technology that offers superior results and flexibility compared to conventional wheel-scoring.
A barcode system available as an option incorporates both book content and cover sensors to ensure accurate cover-to-content matching. Job integrity check and automatic communication with CMT trimmers makes it possible to track books through binding and trimming and to track production statistics to improve workflow efficiency.
‘As the ‘Super Glue’ for printed paper, PUR adhesive excels at binding colour pages printed with digital toners and inks – but PUR is difficult to work with, and until recently it was cost-prohibitive. This explains why PUR perfect binders until now have been either labour-intensive standalone systems, or inflexible multi-million-dollar assembly lines,’ said James Tressler, director of marketing for C.P. Bourg.
Xerox is to demonstrate an in-line version of the new binder operating with its iGen 150 press at Graph Expo, which starts on Friday 28 September 2014.
