摘要： 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.

摘要： The wall of the friction spinning element has bores or holes with a predeterminate bore diameter and a coating on their side facing a fiber feed duct, the coating extending over the bore edges into the bores. Each bore or hole thus formed has a diameter at the bore or hole entrance or inlet which is smaller than the bore diameter of the related bore or hole. Each bore or hole has a cross-sectional area of less than 0.283 mm.sup.2, but amounting to at least 0.07 mm.sup.2. In this way, the undesirable penetration of fibers or fiber parts into the bores or holes is prevented as far as possible when air flows through the bores or holes at the side of the coating, while retaining a hole form or configuration which is favorable from the standpoint of airflow and blockage of the bores or holes.

摘要： The method of, and apparatus for, producing a yarn uses a friction spinning device comprising a perforated first friction spinning drum and a second friction spinning drum which can also be perforated. Two fiber feed passages project to the first friction spinning drum and are each supplied by opening assemblies which individualize or individually separate the fibers. The fibers are transported toward the first friction spinning drum using a feed air stream in the fiber feed passages. This feed air stream is produced by the first friction spinning drum which is maintained under sub-pressure. Advantageously, the fiber double-feed to the friction spinning drum permits supplying two different fiber types to the same yarn end. Also, different inclinations of the fibers at the friction spinning drum can be obtained by different inclinations of the fiber feed passages in order to produce yarns of different character. The first and second friction spinning drums can be each divided into cooperating drum sections to define a first pair of coacting drum sections and spaced therefrom a second pair of coacting drum sections. The respective pairs of drum sections can be operated at different rotational speeds and can be subjected to different vacuum conditions.

摘要： A fiber sliver is drafted to a yarn count in a drafting mechanism and is fed to a false twist unit with a sliver width B1 of 10 to 19 mm. In accordance with the method, by means of the width B1, the fiber sliver leaving the delivery roller pair is divided into a yarn core rotated by the false twist member with a spinning triangle of the width B2 and into edge fibers delivered thereto. The edge fibers are taken up by the rotating yarn core in the suction passage of the false twist unit. The taking-up of the edge fibers occurs in that the front ends of the delivered edge fibers are caught by the rotating yarn core in the region of the narrowest portion of the suction passage and are wound about the yarn core with the same rotational direction as the fiber core but with a substantially larger inclination until the rear end of the edge fibers is wound into the yarn core in the spinning triangle. To maintain the width of the fiber sliver, as delivered by the apron pair and determined by the funnel, until catching of the sliver by the nip line of the delivery roller pair, one of the two aprons is extended into the converging space of the delivery roller pair and both aprons are guided so close to the corresponding roller of the delivery roller pair that the spacings between the aprons and the delivery rollers are close to zero. The spacing between the nip line and the narrowest portion of the suction passage is shorter than the average length of the procesed edge fibers, in order to ensure that the rear end of the edge fibers is not released from the nip line before the edge fibers are wound in the spinning triangle.

摘要： The drafting mechanism comprises an entry roller pair, an intermediate roller pair and a delivery roller pair. An apron hair is mounted such that one of the two aprons projects deeper than the other into the converging space of the pair of delivery rollers, so that the fiber sliver is still diverted, and is thus guided, after the exit or delivery opening of the aprons, on the apron projecting more deeply into the converging space. Further, both aprons are guided sufficiently close to their related delivery roller such that the aprons do not contact these rollers but leave open a minimal air gap, so that only a minimal quantity of the circulating air produced by the rotating delivery rollers can penetrate into the converging space.

摘要： The delivery roller pair are made with continuous uninterrupted cylindrical surfaces so that air flows on the input side converge in the nip and then flow from the central zone thereof to opposite end zones. In addition, the air flows on the output side flow from the end zones towards the central zone. The suction nozzle is disposed downstream and in alignment with the nip so as to receive the fiber material for spinning into yarn.

摘要： In a jet spinning device, in order to enable automatic transport of the yarn from a twist jet to an output roller pair which, for spin-technological reasons, is somewhat spaced from the twist jet, the twist jet is placed in flow communication with a pneumatic guide tube projecting up to the output roller pair. In order to enable automatic threading of the yarn or the like into the output roller pair, the opening or mouth of the guide tube is arranged so close to the output roller pair that the yarn is conveyed into the converging space of the output roller pair and is engaged or entrained thereby.

摘要： In the manufacture of friction spinning drums, in order to be able to select the size of the holes or perforations, on the one hand, to oppose technological fiber loss and jamming of sucked in foreign particles and, on the other hand, to provide airflow advantages, it is proposed to manufacture the friction spinning drum from a thick-walled support and a thin-walled perforated body. As a result, holes or perforations having a sufficiently small cross-section to counteract the above-mentioned fiber loss can be formed in the thin-walled perforated body. On the other hand, holes or perforations having a large enough cross-section to prevent jamming of sucked in foreign particles or other contaminants can be provided in the thick-walled support.
