Abstract: In a spinning process for producing a yarn, fiber material in the form of at least one sliver is opened to a fibrous veil consisting of single fibers, and is deposited on an air-permeable suctioned collecting surface. The speed of the fibrous veil transported on the collecting surface is preferably not higher than the speed of the drawn off yarn. Before reaching the yarn formation line located on the collecting surface, the fibrous veil is divided into a plurality of fiber accumulations and thereby pre-twisted to strands. The position and travelling direction of the strands on the collecting surface is defined by guiding edges of suction slits. The individual strands are guided off transversely to the yarn formation line, whereby the extent of the pre-twist and the extent of the transport force is determined by the angle of the strands to the yarn formation line. Pre-twisted strands are wound around each other along the yarn formation line so that a type of ply-twisted yarn arises.
Abstract translation: 在用于生产纱线的纺丝工艺中，至少一条纱条形式的纤维材料对由单纤维组成的纤维面纱开放，并沉积在透气的抽吸收集表面上。 在收集表面上运送的纤维面纱的速度优选不高于抽出纱线的速度。 在到达位于收集表面上的纱线形成线之前，将纤维面纱分成多个纤维聚集体，从而预捻成股线。 收集表面上的股线的位置和行进方向由吸引狭缝的引导边缘限定。 单个股线横向于纱线形成线被导引，由此预捻的程度和输送力的程度由股线与纱线形成线的角度决定。 预捻股线沿着纱线形成线彼此缠绕，从而出现一种类型的绞合纱线。

Abstract: In a process for open-end spinning at least one sliver is opened to single fibers, which form a fiber veil. The single fibers are fed to a rotating collecting surface which is driven transversely to their travel direction, and are withdrawn from the collecting surface in the form of a yarn with twist along a yarn formation line before the completion of one single revolution of the collecting surface. The single fibers are never slowed down at any point in the sliver-to-yarn process. Immediately after their separation from the sliver, the single fibers are subjected to an exactly predetermined, mechanically controlled speed.

Abstract: The instant invention relates to a spinning process and to a device for the production of a yarn. In the spinning process the fibers are conveyed to a perforated collection surface which is subjected to suction in one zone. They are brought together into a fiber accumulation on the collection surface. The fiber accumulation is drawn off from the collection surface and twisted into a yarn of predetermined twist in a twisting element which follows the collection surface in the direction of yarn draw-off. The fibers are accumulated at a suction edge constituting a collection line and are pre-twisted at said collection line.

Abstract: To control the yarn quality of a yarn produced by a textile machine, particularly a false-twist jet spinning apparatus, there is provided at the end of the spinning operation, however, upstream of the pair of withdrawal rolls for the outfeed of the produced yarn, a yarn tension measuring device. Upon falling outside of a predeterminate yarn tension tolerance or tension range the yarn tension measuring device controls operation of the false-twist jet spinning apparatus such that, as required, there is accomplished an appropriate increase or decrease of the yarn tension of the yarn produced by the false-twist jet spinning apparatus. Alteration of the yarn tension can be achieved, for instance, by varying the blowing intensity or energy of the air utilized for the spinning operation as well as by varying the angle at which there is blown in the air used for the spinning operation or by varying the rotational speed of the delivery rolls which deliver the formed yarn or by selected combinations of these measures.

Abstract: The method of, and apparatus for, producing a yarn using 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.
