Heidelberg, Germany - During the printing show, drupa 2012, Heidelberger Druckmaschinen AG will show a new and improved version of its Eurobind 1300/1300 PUR (polyurethane) adhesive book-binding machine that it claims offers even greater flexibility and cost-efficiency thanks to new automatic functions and solutions.
The machine incorporates a new user-friendly 15-in touchscreen, a new PU glue application nozzle with new side gluing unit, a fully automated cover feeder and special functions for digital printing applications such as the automatic measuring device for block thickness for single-copy production. It also incorporates bar code recognition and -printing to ensure cover and contents are compiled correctly.
In the enhanced PU glue application nozzle, both front and rear block guides and the position of the nozzle relative to the book block can be adjusted. The binder adapts to the book block, not the other way around.
CEWE Color, based in Eschbach (Germany), a leading European producer of photo books has been using Eurobind 1300 PUR adhesive binders from Heidelberg since 2008. Michael Bühl, technology manager at CEWE Color, says, "The new PUR nozzle features absolute dimensional accuracy when it comes to adjusting the block thickness and boasts a tolerance of 0.1 mm. As a result, it can achieve accurate and reproducible sheet edge gluing and effectively prevent any potential glue penetration."
According to Heidelberg, the binder processes PU adhesive in a user-friendly, highly precise, and reproducible manner. The pre-melter and nozzle are controlled via the console, giving operators optimum reliability in production.
The PU nozzle application system operates on a volumetric basis, with the volume of glue applied to each book block precisely controlled by a gear pump. As a result, it is unaffected by viscosity, temperature, and pressure and supplies exactly the same volume of glue to each and every block, thereby ensuring adhesive is used as cost-effectively as possible.
Printing fair drupa 2012 is being held 3-16 May in Duesseldorf, Germany.
