摘要： A open-end spinning assembly includes a silver insertion device, a fiber separating device, a fiber guide device, a fiber collector for collecting, aligning and imparting a rotational movement onto fibers and subsequently applying the fibers to an open yarn end, and a draw-off device drawing-off yarn from the yarn collector. A fed-back yarn end is applied to a piecing fiber quantity fed into fiber collector for forming a piecer. The yarn is continuously drawn-off from the fiber collector and fibers and continuously fed into the fiber collector. A method for monitoring the piecers includes automatically measuring diameter values relative to the longitudinal axis of the yarn for the piecer and for yarn lengths upstream and downstream of the piecer having at least substantially the length of the piecer. The diameter values are electronically stored in memory and compared with comparison values for producing a comparison result. Intervention options are derived from the comparison result for improving future piecers and especially for improving the piecer profile. A piecer monitoring device includes a first device for automatically measuring the diameter values. A second device electronically stores the measured diameter values relative to length in memory. A third device compares the measured diameter values relative to length with comparison values. A fourth device derives intervention options for improving the piecer profile of future piecers.

摘要： A traversing yarn guide (5) that is moved back and forth produces cross winding of yarn on a bobbin at each winding head of a textile spinning or winding machine in order to wind cross-wound bobbins. After a yarn interruption, an auxiliary yarn guide (4) in an active position keeps the yarn in a position that is raised out of the traversing yarn guide (5). In a rest position (40′), the auxiliary yarn guide (4) does not influence the yarn and the traversing yarn guide (5) can grasp and take the yarn to be wound from the auxiliary yarn guide (4). In order to assure a reliable insertion of the yarn (3) into the traversing yarn guide (5) and to assure its correct grasping of the yarn (3), the yarn (3) assumes an initial position within the traversing range after the yarn interruption, which position is set by the auxiliary yarn guide (4) in the active position, before the yarn (3) is lowered into the stationary traversing yarn guide (5) by a position change of the auxiliary yarn guide (4) into the rest position (4′).

摘要： A method for operating a spinning machine with plural spinning stations (1), each case having a take-off roller device (6, 10, 14) for drawing a yarn (9) from a spinning device (2) and a sensor mechanism (26) for checking piecings. When starting a piecing, the theoretical conveying length of the yarn is determined based on the surface speed of the rollers (10, 14), until the piecing reaches the sensor mechanism (26). The deviation of the theoretical conveying length from a desired yarn length, corresponding to the spacing between the spinning device (2) and the sensor mechanism (26), is detected. The deviation is compared with a preadjustable limit value of the permissible deviation. If the limit value is passed, this indicates intolerable wear of the pressure roller (14) and produces a signal.

摘要： It is the object of the invention to propose a method for open-end rotor spinning, wherein the formation of cover yarn, in particular the so-called “belly bands”, is at least appreciably reduced. In accordance with the invention, the fiber flow exiting a fiber guide channel has a directional component in the direction of rotation of the rotor, while the yarn leg (3) extending, from the draw-off nozzle to the rotor groove, is curved opposite the direction of rotation of the rotor, at least near the rotor groove (1), during the spinning process. The creation of this direction of curvature of the yarn leg (3) takes place during the piecing process.

摘要： A method for avoiding ribbon windings in producing cross-wound bobbins at the workstations of textile machines in the “random winding” type of winding, by changing the traversing speed at which the thread is wound onto the bobbin. Each workstation has a single motor drive activated for the rotation of the cross-wound bobbin, and a single motor drive activated for a traversing thread guide. The diameters (DSP k) of the bobbin (8) which are critical with regarding to the development of ribbon windings depending on the width (BSp) of the bobbin (8) and a cross-winding angle (α) are determined, and, shortly before reaching each critical diameter (DSP k), the cross-winding angle (α) is changed to a value (α1), which avoids development of ribbon windings in this diameter region, and the cross-winding angle (α1) is reset to its original value (α) after the critical diameter (DSP k) has been passed.
