摘要： The invention relates to a device for the production of a spun thread from a staple fiber strand by means of air spin method. The fiber guiding element according to the invention includes a fiber conveying channel with a fiber guiding surface, whereby the fiber guiding surface ends at a fiber presenting edge and leads the fibers of the staple strand in the form of an essentially flat arrangement lying next to each other. The fiber-guiding surface is configured in such a manner that it includes a diverting point which causes a deviation of the staple fiber strand, where the deviation is being provided in such a manner that the free fiber ends of the fibers within the staple fiber protrude from the staple fiber strand.

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： Fibers delivered in a freely floating state in a fiber transport passage are to be laid in a predetermined disposition on a friction spinning element, such as a friction spinning drum or disc. For this purpose, an opening region of the fiber transport passage is provided with a converging portion in which the airstream is supplementarily accelerated relative to a preceding acceleration. This supplementary acceleration serves to assist in bringing the fibers into the predetermined disposition on the friction spinning drum. The friction spinning device comprises an opening roller which is rotatably supported in a housing. The housing is connected to the fiber transport passage. The opening of the fiber transport passage extends close to a cylindrical surface of the friction spinning drum. The fibers leaving the opening are transported on the friction spinning drum towards a yarn formation position where they are twisted into a yarn which is withdrawn in a selectable withdrawal direction by withdrawal rollers.

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： An air duct is located opposite a separating opening which opens into the space containing the fiber opening roll so as to receive impurities centrifuged from the opening roll. The separating opening has a wall which forms an acute angle with the opposite wall of the duct so that the impurities can be deflected off the duct wall into the same direction as the air flow in the duct. The duct is narrowed downstream of this point in order to accelerate the air flow and entrained impurities out of the machine via a suction duct. This also stretches out any loose fibers in the flow for rapid removal in order to prevent clogging of the suction duct.

摘要： During a jet spinning method, the rotating fibre ends or the subsequent wound fibres of the spun yarn (70) cause a spinning tension Fs. In tests, a direct correlation has been established between the spinning result and the spinning tension Fs. The aim of the invention therefore is to provide a method for spinning yarn in a jet spinner that permits an ideal spinning tension Fs despite high spinning speeds, thus achieving an optimal spinning result, in particular with regard to the yarn quality. According to the invention, a jet spinner is operated with a spinning tension Fs

摘要： A drafting apparatus for drafting a sliver in the yarn spinning machine preferably comprises upper and lower inlet rollers (2, 3), upper and lower apron belts (9, 6), upper and lower apron belt guides (10, 7) and upper and lower outlet rollers (4, 5). The upper apron belt (9) passes around the upper inlet roller (3) and the upper apron belt guide (10) and the lower apron belt (6) passes around the lower inlet roller and the lower apron belt guide (7) and cooperates with the upper apron belt (9) to define a nipping area (22) between the belts for nipping the fiber sliver (20) as it passes between the upper and lower inlet rollers while being sandwiched between the upper and lower apron belts (9, 6). The sliver is nipped in the nipping area (22) and is subsequently directed by the belts to a nip (25) formed between the upper and lower outlet rollers. The arrangement is such that the sliver is caused to move around a generally S-shaped path and is preferably trapped over the majority of the movement along this path between the two belts. This results in excellent guidance of the fiber and high uniformity of the spun yarn.

摘要： A spinning ring of a ring spinning machine has an inclined flange which is configured such that a travel surface at the inner surface of the spinning ring has a radius (R2) which amounts to about 25 mm. and which merges into a radius (R1) which, at the location of the smallest inner diameter of the spinning ring, amounts to at least 1 mm. A rim or bead at the travel portion of the spinning ring has a height (H) which at most is about one-half larger than the thickness (K) of the rim. Consequently, there can be used travellers having small outer dimensions, so that there can be selected a larger wire thickness of the traveller material. In this way, the service life of the traveller in the ring spinning machine is increased in relation to the prior art. The radius (R1) which is large in comparison to prior art spinning rings and the comparatively small radius (R2) result in an approximately constant surface pressure between the traveller and the spinning ring and afford a stable travel of the traveller during ring spinning.
