The manufacturer of machinery for the nonwovens industry, Graute Nonwoven Machinery GmbH, Senden/Germany, offers the full range of machines for the manufacturing of nonwovens from bale opening and machines for mixing and fine opening, through to complete air-lay systems and carding systems with cross lappers and web drafters.
All of the machines follow a special design concept to make them as maintenance friendly as possible and minimize downtimes. This is achieved with, among other things, large inspection windows for optimum visual controls and individual, retractable sections. This makes it possible, for instance, to completely take the card apart, which significantly improves accessibility to the individual rolls and considerably simplifies cleaning and maintenance.
In recent years the company has brought several innovations onto the market, such as 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 fabricate the product. As a result, the payback period of the carding opener is usually well below one year.
Graute also helps its customers to convert existing systems or undertake complete modernizations.
