Heidelberg Unveils Eurobind Pro
Wednesday, November 16, 2011
Press release from the issuing company
At the Postpress Commercial Information Days in Leipzig, Heidelberger Druckmaschinen AG (Heidelberg) will be unveiling an inline system combining a digital book production line from Hunkeler AG, Switzerland, and the Eurobind Pro adhesive binder. This makes it possible to switch between digital and offset print content on a single adhesive binder. The exceptional processing quality of print products on the Eurobind Pro ensures both production types deliver the same high quality in the end product. Thanks to the combination of minimum makeready times and high production speeds of 6,000 cycles per hour, only one adhesive binder is needed for the cost-effective production of short and very short runs and long industrial-scale runs comprising up to 50,000 copies. This exceptional flexibility is tailored to the needs of innovative print shops as well as specialist manufacturers and service providers focusing on digital printing, publishing, and document management. "This adhesive binder allows our customers to offer a broader range of products and boost their added value. The open interface of the Eurobind Pro and the modular design of the gathering machine will make it possible in the future to add a host of other creative postpress solutions," explains Thomas Krischke, Head of Postpress Commercial at Heidelberg.
Switch between conventional offset and digital printing at the touch of a button
In the face of ever-shorter print runs and increased deadline pressures, books must be produced as quickly as possible to ensure maximum cost-effectivenes. With the Eurobind Pro and the inline book production line from Hunkeler, customers can switch between the production of conventional offset signatures and digitally printed book blocks at the touch of a button. This flexibility broadens the application spectrum of the adhesive binder and also increases its capacity utilization - both prerequisites for the economic operation of such a system.
The range of applications for web-printed digital brochures stretches from operating instructions and scientific publications to conventional softcover brochures (e.g. paperbacks), which are printed decentrally and in run sizes that suit demand. Web-printed digital jobs are folded inline, gathered into book blocks, and fed into the adhesive binder, once again in an inline process. This eliminates the conventional steps such as cutting, folding, and gathering - either manually or using the gathering machine - and the resultant storage of intermediate products. A single roll can accommodate one or more jobs one after the other, which enables the cost-effective production of very short runs and medium-sized runs comprising up to approximately 5,000 digitally printed copies.
Thanks to its exceptional degree of automation for minimum makeready times, the Eurobind Pro is ideal for processing a variety of very short runs that are typical of digital printing. Essential adjustments, such as the book block and format settings, are completed fully automatically on the Eurobind Pro. What's more, the servo-driven feeder modules on the gathering machine enable parallel setup on the fly, so only the feeders actually required for the current production cycle are used. The other feeders meanwhile can be prepared for the next job.
Digital book production line from Hunkeler
Roll unwinding is the first step in the production line. The Hunkeler UW7 unwinder unwinds the digitally preprinted paper rolls with a web width of up to 762 mm (30 in). The subsequent PF7 Double Plow Folder is a double folding module designed specifically for book production. This unit enables the production of signatures with 1, 2 x 4 (double production), 6 or 8 pages. Depending on the paper grade and fold type, the PF7 double folding module can process substrates weighing up to 150 gsm. The following CS6 cross-cutting module cuts the folded paper web with a rotary action and the utmost precision.
However, the key to connecting the book production line to the adhesive binder in an inline configuration is the signature gluing process in the newly developed SD7 nonstop stacker. A starwheel delivery is used to gather the cross-cut folded sheets at a speed of up to 200 meters per minute and to create book blocks via the integrated signature gluing unit. These book blocks are then stabilized for safe transfer to the adhesive binder, where they are processed into the end product.
