摘要： An air spinning device with an injection nozzle and a twisting nozzle is adjusted to the highest possible delivery speed for a desired yarn quality by predetermining the desired spinning tension of the yarn. According to the predetermined spinning tension, the highest possible delivery speed is regulated by changing the injection nozzle pressure and/or the spinning draft. Several spinning stations are installed on the air spinning device. At the spinning station, a measuring device to determine the yarn quality is installed between the twisting nozzle and the draw-off rollers. The measuring device is connected to adjusting devices of at least one spinning station. When the yarn quality is changed, the measuring device, together with the adjusting devices influences at least this spinning station.

摘要： For piecing to a spinning device operating with a pneumatic torsion element, yarn is fed back through the torsion element into a readiness position alongside a drafting mechanism, while the roving is stopped before the end of the drafting zone. The roving is then released, whereby the forward roving end which is leaving the drafting mechanism, and which typically is rendered unsuitable for piecing due to stoppage of the roving, is sucked off. When a roving segment which remained in the drafting mechanism during the prior roving stoppage has been taken away, the roving and the yarn end are brought together and are simultaneously fed to the torsion element so as to be combined. To carry out this process, the drafting mechanism preferably includes before the end of its drafting zone at least one roving stopping device which may be controllable with feedback from a yarn monitor located adjacent the path of yarn being conveyed to a yarn take-up mechanism, such as a bobbin. Furthermore, a suction nozzle can be selectively situated and activated between a pair of exit rolls of the drafting mechanism and the torsion element, for removing controllably the forward end of a roving rendered unsuitable for piecing by stoppage of such roving.

摘要： Fiber material to be spun is presented to drafting equipment in the form of a fiber sliver and is subjected to pre-stretching and main stretching in such drafting equipment. While being stretched, the fiber sliver is gathered together to a minimum width which amounts to at least 1.5 times the diameter of a torsion device to be used with the sliver. After being thus gathered together, the fiber sliver is not further gathered together before having torsion imparted thereto while such diameter is maintained. The width of a condenser situated upstream from the main stretching field amounts here to at least 1.5 times the diameter of a pneumatic torsion device situated downstream from such field. The injector component and torsion component of such torsion device are of identical diameter, from their intake opening to their outlet opening. In this way, hairy and soft yarns, similar to ring yarn, are produced.

摘要： In a spinning device of the type equipped with a torsion element having an injector nozzle and a torsion nozzle which are separated from each other during spinning by a gap which is open to the atmosphere, yarn is threaded for piecing into such torsion element, which is brought into a threading position. Threading is effected with the assistance of negative pressure which is applied to the torsion element from the side thereof which constitutes its inlet side during normal spinning. The gap between the injector and torsion nozzles is sealed against the atmosphere before threading of the yarn. Thereafter, and at the latest at the beginning of the withdrawal of the pieced yarn, the gap is opened once more. A sealing device, which may assume various alternative constructions, is provided to carry out the process by sealing the gap between the injector nozzle and the torsion nozzle during the threading phase.

摘要： A method and apparatus for cleaning fibrous material which is fed in the form of a sliver by a delivery device to an opening roller carried within a housing which opens the fibrous material and feeds the opened fibers to an open-end spinning device. A dust separator opening is provided in the housing between the delivery device and the open-end spinning device. A source of suction is connected to the dust-separator opening and a gauze-like covering extends over the dust-separator opening for maintaining the fibrous material within the effective range of the opening roller as the fibrous material is carried thereover during the opening process. The dust from the fibrous material is withdrawn through the gauze-like covering and the dust-separator opening by the source of suction. The housing can also be provided with a trash separator opening having a separator edge positioned adjacent thereto for separating trash from the fibrous material simultaneously while the dust is being removed therefrom.

摘要： Yarn of a fineness between Nm 60 and Nm 250 comprises fibres from the fur of angora rabbits. The fibres are pretreated with a two-component composition of an antistatic agent and an agent for increasing the adhesability of the fibres. The pretreated fibres, with or without other fibres such as synthetic fibres, are spun together with an uninterrupted carrier thread of a cross-section up to one third of the cross-section of the spun yarn.

摘要： Fiber material is conveyed over a sieve-like surface to remove dust from material. The fiber material is thereby exposed to a suction airstream which is guided through the sieve-like surface and which is guided away from the fiber material at an acute angle which is formed opposite to the fiber transport direction. The fiber material may be aligned in parallel before it is exposed to the suction airstream. In order to orient the suction airstream at the desired acute angle relative to the fiber transport direction, the fiber material is guided over sieve orifices which are inclined at the acute angle opposite to the fiber transport direction.

摘要： A process for rejoining the thread on an open-end friction-spinning device, in which fibers are fed into a V-shaped nip subjected to suction, and the thread formed in the V-shaped nip is drawn off from this and wound onto a bobbin. For rejoining, the fiber feed into the V-shaped nip is interrupted and a thread end drawn off from the bobbin is guided towards the V-shaped nip counter to the spinning direction. This thread end is paid out in front of the V-shaped nip and is stored in a joinable length in a storage station at the end of the V-shaped nip facing away from the bobbin. The bobbin is then advanced towards its drive roller and the thread is drawn off from the storage station. After a predetermined time after the start of the thread draw-off, the fibers are fed again into the V-shaped nip, where they come up against the thread end running through the V-shaped nip and are twisted together with this.

摘要： To end or start the spinning operation on an open-end spinning unit by means of a switching device with which the connection to a spinning element or a delivery channel is alternately unblocked and blocked during the reversal of a switching device, the fiber flow is taken out of the region of the particular fiber path to be blocked, and only then is this region blocked. To influence the fiber flow, the volumetric flow rates of suction air flowing through the switching device are controlled. The switching device (6) has at least one closing member (60) with a first orifice (61) which leads to the spinning element (1) and the cross-section of which is enlarged geometrically in a discontinuous manner in the direction of the orifice opening, and with a second orifice which leads into the delivery channel (51) and the cross-section of which is reduced geometrically in a gradual way in the direction of the orifice closure.
