At the start of 2023, the plant in the Technical Center Felting of the Technology and Development Center of Groz-Beckert was expanded: An online measuring system from Hammer IMS was installed.
Previously, the fabric weight of nonwovens was measured manually at the plant. This process involved taking small, circular nonwovens samples with a defined area from the produced nonwoven sheet. The samples were then weighed, and the area-related mass of the nonwovens was calculated from the measurement values.
This work step is complex and must also be repeated until the correct fabric weight is achieved and at regular intervals during the entire production period for process monitoring.
With the new online measuring system, it is now possible to track a change in the fabric weight during the production of the nonwoven in real time.
The system sends out gigaherz (GHz) waves – similar to smartphone waves – a receiver records them and measures the shielding of the waves caused by the different densities in the nonwovens. The proportion of shielding is equated with a manually measured fabric weight. From this point on, the change in fabric weight can be tracked live on the display.
The fabric weight measurement system makes testing at the Technical Center Felting of Groz-Beckert KG, Albstadt/Germany, more efficient and allows more statistically accurate conclusions to be made about the weight per unit area.
