Herrmann Ultraschall, ultrasonic welding specialist has unveiled new side seam ultrasonic process, known as ‘Cross Direction’ for training pants. Herrmann Ultraschall has developed new ultrasonic module designed for intermittent cross seal applications, which is more rigid with optimised control of the amplitude peaks, frequency shifts and finite measuring and control technology.

“The main benefit of ultrasonics is that no adhesives are used. This makes the production process clean and controllable, leaving the potential for skin irritation is practically ruled out. The seal softness and visual appearance achieved with the ultrasonic welding of nonwovens layers is unrivalled,” said the press release.

Due to new software and modifications, the process can now be optimised even more and the force can be controlled more accurately. All these aspects result in significant reduction of problematic deviations from standards between the first and second seal. Another contribution to the improved parameters can be attributed to the modified anvil drum design.

The new inline process ensures higher production speeds with consistent seal strength, welding of multi-layer materials with varying layers and attractive visual appearance and softness. Hygiene manufacturers can now opt for a cost-effective machine with profitable speeds. (NA)
