Herrmann Ultraschall
Award for best technical innovation in the nonwovens industry

05.04.2022 Herrmann's Elastic Thread Anchoring (ETA) sonotrode has been awarded the prestigious IDEA Equipment Achievement Award 2022. With this award, the nonwovens association INDA honours the best technical developments in the industry.

A creative, novel solution with measurable benefits: This is what the judges demanded from the applicants for this year's IDEA Achievement Awards. In the category "Equipment", the ETA Sonotrode from Herrmann Ultraschalltechnik GmbH & Co. KG (Karlsbad, Germany) was selected by the jury as one of three finalists. The winner was determined by online voting, in which the Herrmann innovation prevailed.

Honour for Walter Herrmann

"In 1996, my father Walter Herrmann won the award for 'Most Innovative Equipment' for our Microgap control, i.e. our first solution for the continuous bonding of nonwovens using ultrasound. It is also thanks to this development that our company has grown so successfully. We want to honour him with this award for our latest innovation," said CEO Thomas Herrmann at the award ceremony on 30 March at the IDEA trade fair in Miami, USA. He accepted the trophy together with his colleague Uwe Peregi, who heads the subsidiary Herrmann Ultrasonics in the USA, from INDA President David Rousse.

Simpler, safer and more sustainable

Herrmann's ETA Sonotrode offers an innovative way to simplify the complex process of fixing elastic threads in hygiene products. Until now, the majority of applications used glue or, if an ultrasonic solution was used, the threads were guided over an elaborately engraved and therefore costly anvil roller. Thanks to a particularly fine and sophisticated geometry on the surface of the ETA sonotrode, elastic threads can now for the first time be guided directly over the welding tool instead of over the anvil roller. This makes the process simpler, safer and more sustainable. Adhesive is no longer required and the risk of thread breakage is reduced.
