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： 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： To piece with a spinning device having a pneumatic twisting unit, a yarn end is back-fed from an output side, through the twisting unit, to drawing equipment, and then inserted laterally into a pair of drawing unit output rollers, from where it is drawn off through the twisting unit in the form of a continuous yarn with a rove being incorporated into it. During the back-feeding of the yarn end to the twisting unit input side, the yarn end is conveyed to a grasping device located at the side of the drawing equipment. The grasping device pulls the yarn end for subsequent insertion into the pair of output rollers past such rollers until such end is alongside the drawing equipment. A yarn presenting device is provided to convey to the grasping device the yarn end leaving the twisting unit input side. The yarn presenting device includes a compressed air nozzle oriented essentially parallel to the nip of the pair of output rollers, the outlet of which is located on a side of the twisting unit across from the grasping device and which outlet is also oriented towards the grasping device to convey the yarn end thereto.

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 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： 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.
