摘要： A condensing zone is arranged downstream of the front roller pair of a drafting arrangement of a spinning machine, in which condensing zone a drafted roving or a sliver is condensed. The condensing zone has a suction device which has a closed hollow profile and which serves as a sliding surface for a circulating sieve belt. The sieve belt transports the drafted fiber strand to a nipping roller, which presses the fiber strand and the sieve belt against the sliding surface at a nipping point. The fiber strand travels over an essentially in transport direction extending suction slit located in the condensing zone, which suction slit extends to the nipping point.

摘要： To ensure for the effective removal by suction of thread breaks, even at long ring spinning machines in an economical manner, a second duct or channel is provided above a package creel and parallel to a first suction duct or channel. Both ducts discharge into a common suction chamber. Connecting channels conduct a portion of the air quantity sucked-up by suction nozzles into the second duct or channel. The cross-section of the second duct is enlarged, with increasing length of such duct, in a manner such that there prevails in both ducts essentially the same mean air velocity.

摘要： A method and apparatus for piecing up a broken entwined yarn being produced on a machine from a bundle of spinning fibers and a binding thread. The bundle of spinning fibers are fed through a pair of delivery rollers into a rotating hollow spindle. The binding thread is carried on a bobbin that is, in turn, carried on the hollow spindle for being wrapped around the bundle of fibers as it passes through the hollow spindle producing an entwined yarn. Upon breaking of the entwined yarn the bundle of spinning fibers is deflected between the delivery rollers and the hollow spindle out of its normal path by a stream of suction air. An end of the entwined yarn is drawn off of a takeup bobbin and fed back through the hollow spindle and is united with an end of the binding thread. The ends of the binding thread and the entwined yarn are then twisted together with the bundle of spinning fibers and the production of the yarn is re-initiated.
摘要翻译：一种用于接合由纺丝纤维束和结合线在机器上产生的断裂的缠绕纱线的方法和装置。纺丝纤维束通过一对输送辊进料到旋转中空心轴中。装订螺纹承载在筒管上，该筒管又承载在中空心轴上，以在纤维束穿过中空心轴时缠绕在纤维束上，产生缠绕的纱线。缠绕的纱线断裂时，纺丝纤维束通过吸入空气流在输送辊和中空心轴之间偏离其正常路径。缠绕的纱线的一端从卷取筒管中抽出，并通过中空心轴反馈，并与结合线的一端相结合。然后将装订线和缠绕的纱线的端部与纺丝纤维束一起扭曲，并重新启动纱线的生产。

摘要： Undoing or removing thread ends of individually transported textile bobbins which are rotated during the transport about their longitudinal axis and which are blasted with compressed air during the transport from at least one blasting nozzle is effected more efficiently by moving the blasting nozzle in the direction of the longitudinal axis of the textile bobbin or the travel direction of the textile bobbin, or both, to obtain controlled intensity and time, particularly to blast certain zones of the textile bobbin longer or more intensively than others.

摘要： A system for connecting a thread suction tube to a tube carrier communicating with a suction channel and for disassembling it therefrom characterized by the fact that it comprises in combination a suction tube having an axial smooth bore with a flared inlet orifice and which is made of an antistatic rigid material, and a tube carrier constituted of a shaped sleeve made of an elastically deformable material. The sleeve has an axial conduit comprising a flared end adapted to facilitate the insertion of the rear end of the suction tube and which is provided with a radius generating a slightly conical section, the diameter of the more restricted cross sectional area is less than the outer diameter of the suction tube. The conical section ending with an annular shoulder, the inner edge of which defines the entrance of a cylindrical section of said conduit, and it is provided with a diameter substantially equal to the inner diameter of the suction tube and it has a flared end. Means are also provided to sealingly connect the said tube carrier to an orifice provided in the side wall of the suction channel.

摘要： A spinning machine and associated operational method include a plurality of adjacently arranged workstations that each have a spinning device for making a thread and a suction nozzle for seeking a thread end on a package. A first suction system includes a first vacuum source and a first vacuum duct extending along the workstations, the spinning devices of the workstations connected to the first suction system. A second suction system includes a second vacuum source and a second vacuum duct extending along the workstations, the suction nozzles of at least a first partial number of the workstations connected to the second suction system. The first suction system and the second suction system are pneumatically completely disconnected from one another.
