Abstract (en)
The method involves rubbing up of isolated fibers on the conveyor (32,43) to form the non-woven material (29,33,34). Separating device contains at least a separating element. The separating element rotates around a rotation axis. The rotation axis is aligned essentially parallel to the conveying direction of conveyor. An independent claim is also included for the device for production of non-woven material.
