Innovation WEEK at GDM Italy
27.04.2016

More than 300 chosen industry guests from all over the world were present at GDM’s innovation week last month in Offanengo (Cremona).

GDM is a world-leading hygiene machine builder. Herrmann Ultraschall was among the hand-picked participating suppliers at the exclusive R&D arena and could demonstrate its ultrasonic technology for the B12 (Baby 1200 ppm) and the BP5-CD (Baby Pull-Up in Cross Direction). For the first time customers were able to see the brand new side seam process in cross direction (CDA) by Herrmann Ultraschall live and in action. The new ultrasonic inline-module CDA ensures the high production speeds as required by the markets with standard deviation rates of almost zero, even with multi-layer changes. The process is stable and repeatable:

  • Machine speeds > 250 m/min
  • Consistent seal strength
  • Welding of multi-layer materials with varying layers (4 - 8)
  • Attractive visual appearance and soft touch
