Problems solved by technology

On the contrary, this also often occurs on open-end spinning machines, so the basic difference is determining the length of yarn to be unwound
[0004] Another fundamental difference is that, on the winder, the inspection device detects flaws in the opposite direction to the production direction
Defects appear slowly, causing gradual deterioration of the yarn quality, causing the winder to recognize the largest defect end first, which is easily identifiable at this time

Embodiment Construction

[0032] figure 1 Describes the percentage deviation from the nominal value that occurs over the yarn length. In the depicted legend, a tolerance range is depicted with dashed lines. The dotted line indicates the maximum permissible percentage deviation of 20% from the nominal value. Below this dotted line, the yarn thickness can be shifted up to the length L 1 , that is, only within the allowed range. In the resulting yarn length L 1 On the contrary, the yarn thickness exceeds the allowable tolerance range, and the yarn emerging from this time is potentially defective due to the reasons mentioned above. length up to L 2 Afterwards, deviations from the nominal value are not permitted and yarn production is stopped. from L 1 to L 2 The thread length that appears is the first thread length I. The length that exceeds the allowable tolerance value can be pre-determined by a function, but the function at this position cannot be further considered. In principle, it can be ima...

Abstract

The invention relates to a method of cleaning out yarn faults at a spinner, especially at an open-end spinner, wherein, the yarn is monitored as it is wound on to a bobbin. On detection of a deviation from a nominal value, the yarn spinning is interrupted and the spinner is stopped at least partially. On detection of a fault, the yarn length to be unwound is registered between the first indication of a fault and the start of a new yarn end.

Description

technical field [0001] The invention relates to a method for removing yarn defects on a textile machine, in particular an open-end spinning machine; in this method the spun yarn is wound onto a bobbin, the properties of the yarn are monitored; when the associated rated value When deviations occur, yarn production is interrupted; at the same time the textile machine is at least partially stopped. Furthermore, the invention relates to a textile machine, in particular an open-end spinning machine, which has a yarn storage device and a testing device arranged before the storage device while the yarn is running. , to monitor yarn properties. In the event of deviations from the desired value, the testing device causes an interruption of the yarn production and an at least partial shutdown of the textile machine. Background technique [0002] In order to ensure the quality of the yarn processed by the textile machine, especially the spinning machine, an inspection device for cont...
