STICKING WITH SUCCESS: A
SMARTER WAY TO BOND BOX SEAMS
Using a Side Seam Gluing Solution from Baumer hhs to bond the side seams of folding boxes has
provided efficiency and productivity
benefits to a premium carton manufacturer
accepted due to lack of an alternative method. “With Baumer hhs’ Side Seam Gluing Solution
we have far fewer gluing issues. Adhesive doesn’t flick off, which can create troublesome residue buildup either on the cartons themselves or on the machine. And with the ability to apply short segments or ‘stitches’ of glue, we achieve a much more precise application and overall cleaner finish.” Of further benefit, the operator has greater
control over the application on the run. It is possible to choose exactly how much glue is applied, according to the speed of the line, unlike a wheel system where it’s almost a one-size-fits-all approach. Pugh added: “In addition, we save a substantial amount of cleaning time at the end of each shift. Previously, we would allow 45 minutes, but this is now as quick as 30 seconds.”

hen looking for a new folding-gluing solution, premium carton manufacturer Qualvis needed a solution that would
provide speed, precision and control. To meet the demands, the company chose a Koenig & Bauer machine, complemented by an innovative Side Seam Gluing Solution from Baumer hhs. The adhesive technology replaces the use of glue wheel units used to bond the side seams of folding boxes, delivering efficiency and productivity benefits to converters. “Our focus is on artisan brands, premium
food packaging and cosmetics markets, which have seen positive growth in recent years,” commented Marcus Short, joint managing director of Qualvis. “With our mix of work, a percentage is high volume, straight-line gluing, and we required machinery and equipment that would enable us to compete more efficiently, in line with market demands.” The Koenig & Bauer folder-gluer became fully
operational in July 2024, with its capabilities meaning the company could reduce the number of folder-gluers at its Thurmaston, Leicester, site from five to three.
PERFECT GLUING In folding carton production, adhesive is
traditionally applied by a glue wheel or disc to bond the side seams. However, this technique introduces issues such as glue waste and lengthy production floor cleaning time. Baumer hhs’ Side Seam Gluing Solution consists of a gluing nozzle that applies adhesive to glue flaps from below in a non-contact process. The combination of the PX 1000 cold glue
application head, Xact Up Controller and DPP8 glue delivery pump is at the heart of the system. The PX 1000 high closing force ensures perfect gluing and prevents contamination, with the integrated light barrier reliably detecting every glue flap and independently controlling the gluing process. Non-contact application also offers the option of segmenting the bead of glue, rather than applying a stream of adhesive. Of further benefit, this ‘glue save’ mode makes it possible to significantly lower adhesive
consumption, cut costs and reduces CO2 emissions for the first time inside seam gluing. Jordan Pugh, head of operations at Qualvis, said: “I think the feeling at first was ‘why would you replace the wheel units?’ Now the question is, why would you not? Glue gun type application is commonly used for intricate, low speed jobs, yet this system runs as fast as we want it to, without all the issues that have simply become
A SUSTAINABLE SOLUTION Baumer hhs has made the switch to non- contact gluing simple for converters. While Qualvis has invested in a new folder-gluer, the technology can be integrated and retrofitted onto existing machines. The existing glue wheel unit is removed from the machine and the Side Seam Gluing Solution installed in exactly the same position. Designed to ensure ease of use and
accuracy, the gluing nozzle applies adhesive to within 1mm on glue flaps from beginning to end, and the system can be configured to specify precise application quantity and glue pattern. Glue consumption can be reduced by up to 50% thanks to the ability to apply short segments of glue, instead of a continuous bead, without compromising adhesive strength in the side seam. Christoph Herrmann, business development manager for Baumer hhs, commented: “The Side Seam Gluing Solution supports maximum availability of folder-gluers and increases both output and added value. The Xact Up controller’s automatic mode reduces set-up time during job changeovers and provides complete control to the operator in relation to adhesive application. Additionally, it enhances the sustainability of box production by reducing glue waste and water used during cleaning.”
