摘要： A piecing device with an evaluation arrangement for determining parameters of an automatic piecing process at a spinning station (1) of an open-end spinning frame, wherein a control device is provided which, initially in a test phase, controls the creation of at least one test piecing without a supplementary delivery of additional fiber and the subsequent removal of the created test piecing. The evaluation device is designed for determining the length of a thinner extent of the test piecing downstream of the test piecing as viewed in the direction of yarn travel, and for the determination from the detected length of the thinner extent an amount of supplementary delivery of additional fiber required for compensating the thinner extent. A reduction of the draft which is effective during the test phase assures an interference-free checking of the test piecing. The optimization phase for piecings is shortened and leads to a more accurate result when determining the supplementary delivery of additional fiber.

摘要： A method includes dividing a yarn into various sections with reference to the pieced yarn section, with each section being characteristic of the piecing process. A yarn profile in each section is measured and evaluated against criteria specific to each section, whereby a yarn defect and its position on the yarn are determined and from which the cause for the defect is determined. The pieced yarn section is also divided into three subsections and each subsection is measured and evaluated against certain subsection criteria for the detection of fluff, trash accumulation and fiber sloughing.

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.

摘要： A method for producing graduated precision windings on cheeses in an open-end spinning system. The winding ratio is reduced in stages, in increasingly smaller graduations, as the cheese diameter increases during the bobbin travel of the cheese. The graduations do not exceed the value of 0.3 and are each selected such that changes in the crossing angle are within a tolerance range of less than ±0.8°, and the least number of diamonds occurring during the building of the bobbin can be completely filled. The cheeses thusly produced are distinguished by a stable construction, high density with uniform distribution of density over the entire yarn package, and excellent payout properties.
