New calender, Wetlaid for glassfiber
The new calender offers a number of features that are useful during operation, e.g. user-friendly access to all relevant areas of the calender, complete data management for the calender process and product quality in real time, and extended maintenance intervals.
Overall, Andritz has focused on versatility and flexibility in development of the new textile calender. In addition, the calender contains an innovative, deflection-controlled roll, the Raconip TT. It offers very high flexibility by providing unrestricted profiling over the entire fabric width by means of hydrostatic pistons. This ensures e.g. absolute flatness and exact air permeability. The new calender was developed in cooperation with Rolf Ramisch, a well-known specialist in textile calender technology.
Andritz will also introduce visitors to the processing of glass fibers with wetlaid technology. Glass fiber as a basic component for nonwovens is an outstanding composite material and offers numerous advantages that lend the resulting products unique properties. The manufacture of products based on glass fibers requires particularly gentle treatment in the stock preparation and laying processes. At the Techtextil, the company will present details of wetlaids for glass fiber composites for the first time.
Another focus at the Techtextil will be the needlepunch technology, which the company has been supplying successfully for many years for geotextiles, roofing materials, filtration, technical felts, carpeting, etc. One of the key technologies with top performance is the needlelooming process, which gives the material the decisive properties for consistently high quality. Andritz needlelooms include pre-needling units as well as standard needlelooms and, above all, specialized needlelooms that can be fully adapted to the customers’ needs. With a 3D-print model of the SDV needleloom at the stand in conjunction with Augmented Reality, visitors can gain a unique insight into the Andritz smart service solutions marketed under the Metris technology brand name.
