Abstract (en)
[origin: EP2740821A1] The air spinning device has a fiber belt (4) which is stretched by a stretching unit (5) and is supplied to an air spinning equipment (6) for generating a yarn twist, where the fiber belt is withdrawn from the air spinning equipment and is wound onto a cross-wound bobbin. A false twisting unit (41) is arranged in a pre-drafting zone of the stretching unit. The false twisting unit is granted with alternating direction of rotation of the fiber belt, before it is moved in the main drafting zone on yarn count and is supplied to the air spinning equipment.
