Problems solved by technology

When further processed, kinks occur due to yarn layers that are close together, which can entrain multiple yarn layers when subsequently unwinding and cause yarn breaks

Embodiment Construction

[0033] figure 1 Shown at various stations is the unwinding of yarn 2 from a feed bobbin 1, in particular a bobbin produced on a ring spinning machine, which is wound onto a cross-wound bobbin 3, for example a conical cross-wrap around the bobbin.

[0034] The cross-wound bobbin 3 held by a pivotable creel, not shown, rests against the bobbin drive roller 4, in particular against a so-called guide drum, with which the cross-wound bobbin 3 is rotated and the yarn 2 is drawn The cross-wound bobbins 3 are fed axially and traversingly. However, other types of yarn traversing devices are also conceivable within the scope of the invention, for example so-called finger yarn guides.

[0035] The yarn 2 (which is usually the yarn formed on the ring spinning machine) passes through the yarn guide 5, the controllable yarn tensioner 6, the yarn tension Sensor 9 and sensor in the form of yarn clearer 8 . The yarn tensioner 6 applies a predetermined clamping force to the running yarn 2 ....

Abstract

The invention relates to a method for controlling the acceleration of a package drive roller (4) at a station of a textile machine producing cross-wound packages in which the package drive roller (4) engages with friction Drive the winding bobbin (3) in a manner, and wherein the winding progress is detected during the winding process to sequentially accelerate to a predetermined acceleration level, wherein not only the angular velocity of the bobbin driving roller (4) but also the The angular velocity of the winding bobbin (3) is detected and compared with each other, the acceleration is started to the next acceleration stage according to the result of the comparison, and during the start-up process the corresponding acceleration of the winding bobbin (3) can be The winding schedule controls the start of the acceleration stage of the package drive roller (4).

Description

technical field [0001] The invention relates to a method for controlling the acceleration of a bobbin drive roller at a station of a textile machine producing cross-wound bobbins, in which the bobbin driving roller drives the winding bobbins in a frictional engagement , and wherein the winding progress is detected during the winding process. Background technique [0002] Textile machines for the production of cross-wound bobbins have long been known; they generally consist of a number of identical stations arranged side by side, and bobbins with a relatively small amount of yarn material are rewound into large-volume cross-wound packages On bobbins, these cross-wound bobbins are required on textile machines such as looms downstream of the production process. In other textile machines, such as rotor spinning machines, friction spinning machines, pneumatic spinning machines, such a winding station is combined with a spinning station to realize the winding of cross-wound bobbi...
