摘要： Method for spooling a thread (9) on a textile machine which produces crosswound bobbins (8) and has a multiplicity of work stations (1) of the same kind, wherein each work station (1) comprises a thread traversing device (24) for laying the thread (9) during the normal operation of the textile machine with a nominal stroke on a crosswound bobbin (8) which is driven by a winding shaft (23), and an apparatus (2) for eliminating the interruption of the thread (9), wherein, after the thread interruption has been eliminated, first of all a defined thread length is stored in a thread storage device (12), wherein the nominal stroke of the thread traversing device (24) of the work station (1) is shortened after the elimination of the thread interruption for the duration of spooling of a defined thread length onto the crosswound bobbin (8).

摘要： The invention relates to a method for avoiding ribbon windings in the production of winding-on bobbins which are wound as a ‘randomly wound package’ type on the workstations of textile machines which manufacture crosswound bobbins, by changing the crosswinding, with which the thread is wound onto the winding-on bobbin, wherein the workstations have in each case a single-motor drive which can be actuated in a defined manner for rotating the crosswound bobbin and a single-motor drive which can be actuated in a defined manner for an oscillating thread guide. According to the invention, there is provision for the diameters (DSP k) of the crosswound bobbin (8) to be determined which are dependent on the width (BSp) of the crosswound bobbin (8) and a crosswinding angle (α) which is selected during winding of the crosswound bobbin (8) and are particularly critical with regard to a ribbon winding, for the crosswinding angle (α) to be changed in each case briefly before a critical diameter (DSP k) of this type is reached to a value (α1) which precludes the production of a ribbon winding in this diameter region, and for the crosswinding angle (α1) to be reset again to its original value (α) after the critical diameter (DSP k) has been passed.

摘要： The invention relates to a method for operating an open-end spinning device (1), comprising a spinning rotor (2) and an opening roller (12), which can be controlled so as to be driven individually independently of one another, wherein after an interruption in the spinning process takes place as a result of the detection of the absence of a thread, a piecing operation is initiated, comprising a piecing process, in which an upper thread passes through a fiber ring formed in the spinning rotor (2) and is connected to the latter, and a subsequent drawing-in accumulating process which serves to reduce a thin point in the thread following the piecer, wherein during the piecing operation, the opening roller (12) is temporarily driven at a piecing speed which is higher than the operating speed of the opening roller (12).
