摘要： In preparation for the start of spinning with an open-end spinning apparatus, suction is provided outside a fiber transport path on the periphery of an opening roller. Such suction is greater than spinning suction which exists at the mouth of a feed channel leading to the fiber-collecting surface. The fiber stream is thereby guided beyond such mouth to be sucked off. At commencement of actual spinning, this added suction is inactivated, to permit the fiber stream to be initially supplied to the fiber-collecting surface. The fiber stream may be controlled with a suction source connected to a sucking-off orifice via a switching device and a suction line. Less conspicuous and more even thread joins are thereby obtained. Control of suction changes may be effected automatically from a servicing trolley, or in other manners. The invention may be practiced with a variety of types of spinning machines, including but not limited to open-end spinning machines having open end spinning rotors for thread formation or a plurality of friction rollers therefor.

摘要： A method and apparatus for piecing a yarn in a spinning rotor of an open end spinning device is disclosed wherein an increased quantity of fibers is momentarily fed into the spinning rotor after the yarn is returned to the spinning rotor, whereupon the fiber supply is reduced to the normal supply quantity. Preferably, during termination of the spinning process, fibers are stored between a supply device and a fiber opening device which on commencing the piecing process are suddenly released, while at the same time the fiber supply resumes at the normal rate. For effecting the method an abutment surface (110) is preferably provided in a feed channel (11) on the side of a clamping point (15) of a clamping lever (5) for acting on the feed channel (11) facing away from the opening roller (2). The abutment surface (110) is abutted by a tow guide funnel (51) of the clamping lever (5) during a first part of the pivotal movement of the clamping lever, while during a second part of the pivotal movement of the lever, a clamping end (51) of the clamping lever (5) engages the fiber tow 4 at the clamping point (15) of the feed channel (11) and the guide funnel lifts from the abutment surface (110) while the feed channel is displaced away from the effective area of a fiber opening roller 2. A fiber store 6 is built up between a feed roller 10 and the fiber opening roller 2 during pivotal movement of clamping lever which is actuated by electromagnet 55 in response to a yarn break sensed by monitor 31. Upon release of the clamping lever 5 after stopping and restart of the spinning process, the feed channel is released bringing the fiber store suddenly into the operating area of opening roller 2 for release of the stored fibers in the spinning rotor 3 while at the same time normal fiber supply resumes.

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： 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.

摘要： An improved method and apparatus for stringing up or re-stringing a balanced ply-twisted combination yarn of two components to insure strong piecing-up points. The end of the combination yarn and the end of a continuous filament yarn, which becomes a component of the combination yarn, are both prepared for piecing and inserted into the rotor of an open-end spinning device. Upon start up, the combination yarn engages staple fibers in the rotor consolidating groove while the continuous filament yarn engages the combination yarn within the rotor without any contact of the continuous filament yarn with the rotor consolidating groove.

摘要： To improve the re-piecing operation, especially in terms of its success rate, at high spinning speeds, the free thread end cut to the length of a piecable end and retained after cutting the length is exposed to a turbulent air flow which causes it to execute whiplash-like oscillations. The surface of the thread end is thereby roughened. The thread end prepared in this way is subsequently transferred to the fiber-collecting surface of the open-end spinning apparatus. The roughening of the surface of the free thread end is accelerated when the end is whipped against an edge-like projection or a rough surface.

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： 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.
