When producing web-shaped materials made of film, nonwovens, paper or textiles, manufacturers regularly have to deal with wrinkles in the material. To prevent wrinkles, spreader rolls are used. Spreader rolls have the task of realizing wrinkle-free production and thus minimizing waste. Since previous systems were not entirely convincing, DRECKSHAGE GmbH & Co. KG from Bielefeld has taken on this problem and developed a new, highly efficient solution - the EcoStretchRoll.
The EcoStretchRoll is a smooth-running roller based on the aluminum EconomicRoll roller profile, which is equipped with special rubber spreading rings. The latter realize a controlled, effective spreading of the web from the center of the roll to the outside.
Users can thus produce crease-free - without rejects, marks on the surface or downtimes for adjusting the system.
The EcoStretchRoll is used wherever wrinkles could occur. It is installed like an Idler Roller, without a predefined direction of rotation, without adjustment of the roll, and independent of the wrap angle. All these advantages already work from a layer thickness of <4 μm.
