Muller Martini Unveils Bolero B9 Perfect Binding Line

(Press Release) Unveiled for the first time at IPEX 2010, the Bolero B9 perfect binding line from Muller Martini features a 13% increase in cycle time, new PUR SPN side glue nozzle and the electrostatic attachment of inserts in the new 3694 rotary gatherer. The Bolero B9 is designed to meet up-to-the-minute perfect binding requirements.

The Bolero, which has established itself as a successful product since its first appearance six years ago, has become an even more appealing perfect binder thanks to an increase in performance from 8,000 to 9,000 cycles per hour, particularly for magazines and catalogs in the mid-range market. The declining run sizes seen throughout the world over the past few years have meant that bookbinders have had to produce an ever-increasing number of jobs per shift. At the same time, production has become more demanding, as the attractiveness and therefore the complexity of perfect-bound products using special covers, inserts and cards has become increasingly important.

3694 Rotary Gatherer: Electrostatic Card Attachment
This presents new challenges to rotary gatherers in particular. The new 3694 rotary gatherer from Muller Martini, which was presented alongside the Bolero at IPEX 2010, fulfills these requirements in several aspects. Designed for a flexible product make-up and with the ability to process a wide range of signatures, the new rotary gatherer not only offers the possibility of loading from both sides and quick changeover times, but it is also equipped for the electrostatic attachment of cards, eliminating the need for a separate inserting procedure.

VPN and SPN: Substantially Lower Glue Costs
As a result of its outstanding quality characteristics, in particular with coated papers, polyurethane (PUR) is becoming increasingly popular. The Bolero B9 line can increase melting capacity by 30 percent using the new PUR VPN book spine nozzle (Volumetric PUR Nozzle), which represents a significant increase in production for thick and two-up products. The excellent quality is maintained from one book to the next, even at high production speeds, as the PUR adhesive is always freshly melted, produced in optimal volumes and of consistent viscosity.
