Embodiment Construction

[0021] figure 1 A side view of the station 2 of the open-end rotor spinning machine 1 is shown. Such an open-end rotor spinning machine 1 has a plurality of such workstations 2 arranged side by side in each case on its two machine longitudinal sides. Here, the structure and working principle of the stations 2 are the same, so only one station 2 will be used for description.

[0022] figure 1 with figure 2 Shown is a station 2 with an open-end spinning device 3 and a winding device 4 including a suction nozzle 25 . As is known, a fiber sliver 6 stored in a spinning barrel 5 is spun into a yarn 7 in an open-end spinning device 3 . The yarn 7 is then wound onto a cross-wound bobbin 8 in the winding device 4 . The cross-wound bobbin 8 is held in the winding device 4 on the creel 9 during the spinning / winding process, where it is driven by a bobbin drive roller 10 with a friction fit. The creel 9 is pivotably mounted about a pivot axis 11 .

Abstract

The present invention relates to a method and a device for determining the necessary speed of rotation of a coil drive roller, which particularly reduces rotation speed fluctuation of crossly wound coils (8) when a winding stroke is started. In a station (2) of a spinning machine (1), besides cylindrical crossly wound coils (8), conical crossly wound coils are manufactured in a so-called twisting winder (4). For the uniform roller structure, feeding of a constant winding tension to the yarn (7) is very important. Winding tension fluctuation can cause yarn fracture besides yarn layer loosening, and affects continuous spinning and winding processes. For preventing this effect, the invention prescribes that: angular momentum of the crossly wound coils (8) is detected through the sensor and calculated according to time sequence of a corresponding driving diameter before paving or splicing, so as to select the rotation speed of the coil drive roller (10) before the winding stroke.

Description

technical field [0001] The invention relates to a method for determining the required rotational speed of a bobbin drive roller when driving a tapered sleeve or a cross-wound bobbin held at a station of a textile machine for producing cross-wound bobbins In a creel in which independently motor-controlled bobbin drive rollers of stations frictionally drive the tapered sleeve and the subsequent cross-wound bobbins; the invention also relates to a textile machine for the manufacture of cross-wound bobbins carrying out said method. Background technique [0002] In the workstations of spinning machines, in so-called winding machines, not only cylindrical but also conical bobbins are produced, it is especially important to feed the yarn with a constant winding tension with regard to its uniform bobbin structure. Yarn winding tension not only has a decisive influence on the structural quality of the package, but also affects the continuous progress of the spinning or winding proces...
