New Adhesive Monitoring System from Muller Martini

Muller Martini’s newly developed Adhesive Monitoring System (AMS) gives customers key benefits in terms of product quality and cost control. With AMS, a laser consistently monitors glue application during the production of softcover books. Glue application is measured reliably even for differing glue patterns thanks to the seamless integration of the adhesive monitoring system with the control system of the latest generation perfect binders. ‘The system measures extremely accurately and it’s capabilities are really impressive,’ said Michael Scherrer, Production Manager at the Scherrer bookbindery in Urdorf in the Swiss canton of Zurich. ‘You can rely on the AMS, as it continuously checks every book and halts production immediately if it detects an error.’

The data from the AMS is transferred to the operator monitor and the glue profile is clearly displayed on a color-differentiated graphic. This allows optimizing the applied quantity by fine-tuning directly on the monitor, thereby minimising glue consumption and cutting costs, while maintaining the quality of the end products. ‘Often too much glue is used in perfect binding,’ said Scherrer. ‘AMS allows you to use less glue, without having to sacrifice quality. And reduced glue consumption naturally translates to more cost-effective production.’

The AMS not only measures and adjusts the glue quantity, but also reliably detects any gluing errors such as accumulations, gaps or dirt in the adhesive-free zone, allowing the operator to react to errors individually or automate their handling. That guarantees the higher quality of delivered books, thereby reducing complaints and leading to greater customer satisfaction overall.

Scherrer is in no doubt, ‘The Adhesive Monitoring System for perfect binders is just as important as automatic signature image recognition Asir 3 for gathering machines when it comes to ensuring the high quality of the end products. Control systems for the whole production process are the future, which is why I’m convinced that AMS will become just as standard in perfect binders as automatic signature image recognition Asir 3.’

The new AMS can be used in Muller Martini’s Bolero and Corona perfect binding lines, as well as most Alegro assemblies. It can also be retrofitted on existing perfect binding lines depending on the machine configuration. By making a relatively small investment, graphic arts businesses will enjoy cost and quality benefits. Updates and upgrades to existing equipment under MMServices, the global service portfolio from Muller Martini, can increase a company’s ability to compete and enter new markets.

The AMS monitoring system can be used for gluing using a glue pot or for VPN nozzles depending on the configuration – with either PUR or hotmelt gluing.
