The producer of nonwovens machinery Graute 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 Airlay systems and Carding systems with cross lapper and web drafters. At the end of 2019, the foundation stone of the additional winding technology business branch was laid in Luxembourg and since then Graute has been dedicated to the design of various winding machines for web-formed materials. 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.
A topic that has become increasingly important in recent years is the recycling of edge stripes and deposit rolls. Here, Graute has developed an opening machine that can re-open 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 produce the product. As a result, the payback period of the Carding Opener (CO) is usually well below one year.
Another innovation from Graute Nonwoven Machinery is the Multi Purpose Opener (MPO). Compared to the CO, this offers a cheaper variant for opening medium to partly heavily consolidated edge strips. At the ITMA, the MPO will be available for customer testing.
