Abstract (en)
[origin: US4696155A] A friction spinning device has a pneumatic fiber transport passage or channel inclined at an angle to a perforated friction spinning element and a yarn formation position of the perforated friction spinning element is located at a spacing from an opening of the pneumatic fiber transport passage or channel. In such a friction spinning device, it is desired to ensure that the fibers located on the perforated friction spinning element are transported towards the yarn formation position neither parallel to nor at right angles to the yarn formation position. For this purpose, the perforations of the perforated friction spinning elements are so arranged that straight lines joining the perforation centers are disposed neither parallel to nor at right angles to the yarn formation position. In this way, fibers transported onto the perforated friction spinning element are laid on such perforated friction spinning element in the direction of the rows of perforations due to the intensity of the transporting air. In this way, a desired or appropriate disposition of these fibers is ensured.
