Tired of the hassle and cost associated with producing a few hundred to a couple of thousand PUR-bound books a day? Are you throwing away more adhesive at the end of a job than what was used to run the books through the binder? Do you cross your fingers every time an important title is shipped to your customer in hopes that the pages do not fall out? If any of these are a daily concern, then why not consider the latest technological advancements in PUR-nozzle applicators and integrated adhesive monitoring systems.
Today’s highly-automated PUR application systems are designed to apply a thin film of glue uniformly across the spine with accuracy and consistency book-to-book, even in a book-of-one workflow where every book can be a different length and thickness. Due to the volumetric (spine length x book thickness x glue film) dispensing principle of the PUR nozzle, the precise amount of glue is applied every time. No longer do you have to rely on traditional open-wheel roller pots with their inherent material and labor waste to accommodate the variation associated with running short-run jobs on a daily and weekly basis. What used to take 30-60 minutes at the start and end of every shift, now takes two minutes or less–with only a tablespoon of adhesive being thrown away.
And in this time where books must be shipped faster and faster, sometimes within hours of receiving the order, it is imperative that quality is not sacrificed. Since PUR books cannot be opened immediately after coming off the binder, a good adhesive monitoring system that is integrated into the binder control platform is a must to ensure each book has the right amount of glue (not too much or too little) on it, as well as no voids. A camera-based system that closely monitors each book spine after the adhesive is applied will detect if there is a clog in the nozzle and immediately alert the operator to guarantee no defective books are shipped out.
So, if your bindery continues to struggle to produce PUR books efficiently, take some time to review the cost-saving developments in the latest integrated PUR-nozzle technology and quality control systems.
