Embodiment Construction

[0032] The invention is explained in more detail below on the basis of a single schematic diagram, which shows a schematic side view of a draw frame, which is more precisely an example of a spinning frame or spinning preparation machine. According to the example a plurality of substantially untwisted adjacent fiber slivers FB are shown in the draw frame (the fiber sliver here is only produced in the front), it is also possible that only one fiber sliver FB is fed to the draw frame, which is made of It is obtained directly from a card or comber in the front. A bell mouth 12 for compacting the fiber sliver is arranged at the inlet of the draw frame. Alternatively, another compaction device may be applied. In addition, the fiber sliver passes through the component scanning devices 2, 3 of the input sensor 1, at this time a plurality of individual fiber slivers FB have become a compressed fiber sliver FB', and enter the drafting device 4 of the core part of the draw frame. The d...

Abstract

A worsted preparation machine with a drafting device (4) for drafting, for example, a fiber bonded sliver (FB') made of cotton, polyester or the like, characterized in that a computer (30) is Designed and installed, the computer can compare the evaluation of the spectrograms (SE, SA, SL) and / or curves of the signals of fiber-bonded sliver segments, where the test signals come from at least two of the three sensors mentioned below Taiwan, three sensors namely the input end sensor (1), the output end sensor (11) and the sensor of a laboratory test instrument (27), the laboratory test instrument is designed to be used for establishing the spectrogram and Graph to localize the source of a defect in one or more fiber slivers. The invention also provides a corresponding method.

Description

technical field [0001] The invention relates to a spinning machine or preparation machine for spinning, with a drafting device for drafting a fiber-bonded sliver of material such as cotton, polyester or the like, with at least one draft formed by two identical drafting units. Drafting zone with a sensor for determining the draft height in at least one drafting zone, at least one input sensor connected upstream of the drafting device and / or at least one output sensor connected downstream of the drafting device , for determining the weight of the input or output fiber-bonded sliver section per unit length fiber sliver cross-section or fiber, and the test signal from the input and / or output sensor, at least for establishing the amplitude-frequency-function (spectrum graph) and / or amplitude-time-function (graph). The invention likewise relates to a corresponding method. Background technique [0002] It is known that a spinning preparation machine with a drafting device, with c...
