Herrmann Ultrasonics Expands Nonwovens Lab – Nonwovens Industry Magazine

The Herrmann Ultrasonics Nonwovens business unit, a specialist and technology leader in the field of continuous welding of web materials, including nonwovens, films, foils and fabrics since 1994, has made significant investments in the expansion of the Nonwovens laboratory and the upgrade of the most modern and fastest ultrasonic laboratory. calendar, the ULC 600+, located at the headquarters in Bartlett, IL.

The investment will allow the company to strengthen its global presence and support growing North American markets and demands with increased application testing, customer support and Herrmann Engineering.

The laboratory’s investment consists of:
• Ultrasonic bonding processing speed capabilities in excess of 600 m/min (2,000 ft/min).
• Upgrade to ULC 600+ Ultrasonic Lab Schedule with state-of-the-art Allen Bradley controls and controls, plus the latest web tensioning system.
• Addition of elastic unwinding and guiding systems to execute the elastic anchoring solution patented by Herrmann Ultrasonics.
• New Windows-based MICROGAP G4 HMI ultrasonic bonding solution platform.
• Increase in the surface area of ​​the laboratory.
• Quick anvil exchange systems to efficiently run different models for the same application.
• New test and measurement area.

Ultrasonic welding of web materials is an extremely fast and stable process that is easily repeatable and readily available without the need for preheating or consumables such as adhesives. This scalable technology enables simultaneous embossing, lamination and die-cutting from narrow pattern widths to applications over 4m wide. To ensure high product quality, the continuous bonding of materials requires a precise and repeatable manufacturing process. The upgraded ULC 600+ Ultrasound Lab Schedule can be used to simulate the production environment and perform feasibility testing for a variety of markets such as consumer, medical, wound care, hygiene, filter, wipes, face masks and more.

Uwe Peregi, President of Herrmann Ultrasonics, explains: “Very thin and flexible materials, such as 9 GSM, can be better controlled with a new web tension and control system. With our brand new rapid exchange system for ultrasound stations, we can experiment with different ultrasound technologies – static or rotary – in just one day. Thus, our customers will save time and money.

In addition, new documentation and analysis tools are available, such as the OPCUA interface which can provide all relevant application-specific process data.

Herrmann Ultrasonics can meet project requirements through consultation and application development in its nonwovens laboratory.
