For more than 20 years, Graute Nonwoven Machinery GmbH, Senden/Germany, has been developing, designing and building machines for the nonwovens industry. The full range of machines for the manufacturing of nonwovens is offered, from bale opening and machines for blending and fine opening, through to complete airlay systems and carding systems with cross lapper and web drafters.
In the meantime, the company also offers quality winding technology. At the end of 2019, the foundation stone was laid in Luxembourg for the additional business branch dedicated to the design of various winding machines for web-formed materials. In addition to the classic turret discs and master-roll winders, specially tailored offline systems, as well as fully automatic high-speed slitting units are also offered.
All machines are designed according to a special construction concept, the aim of which is to make the machines as user-friendly as possible as well as easy to maintain in order to minimize downtimes and ensure smooth production. One example is large transparent windows, which serve for optimal visual control. In order to ensure a considerably improved situation with regard to cleaning and maintenance of the carding machines, individual sections can be separated or the card can be moved apart completely in just a few steps.

One of the company’s most recent innovations is the continuous mixing opener CMO-W2, which ensures a very good blend of the different fiber types and a gentle dissolution of the fiber flakes by continuously feeding 2 types of fiber already at the first opening point. As a result, the production capacity of the opening can be significantly increased and the use of large space-consuming mixing boxes is no longer necessary.
Another topic that has become increasingly important in recent years is the recycling of edge stripes and deposit rolls. Here, the company has developed an opening machine that can reopen very heavily consolidated materials, that previously had to be disposed of for a fee, and return this material to the process. This results in a considerable savings potential since no disposal costs are incurred and fewer new fibers have to be used to manufacture the product. As a result, the payback period of the carding opener is usually well below one year.
Graute Nonwoven Machinery is also a partner in the modernization of existing lines in the nonwovens industry and sees itself as a solution provider for complete turnkey lines. The company will be present at the Index in Geneva/Switzerland from October 19-22, 2021.
