Center of Excellence in Nonwovens
Technical Equipment
Our technical equipment, which is installed in three different technical centers, range from small-scale with working width of 60 cm, 100 cm up to semi-industrial 240 cm working width and offer tailor-made developments from orientation testing to small series. The complexity of these technical centers and the perfect areal concentration also allow for diverse and sometimes exceptional technology combinations.
