Abstract

Die Erfindung bezieht sich auf eine Vorrichtung zur Bildung eines Faserbandes mit einem ersten, regulierten Streckwerk (10) mit mehreren Walzenpaaren (11,12,14) zum geregelten Verstrecken der dem Streckwerk zugeführten Fasermasse (8), wobei das von dem Streckwerk abgegebene Faservlies (28) zusammengefasst und einem Messorgan (32) zugeführt wird, von welchem das gemessene Fasergut anschliessend zu einem zweiten Streckwerk (40) überführt wird, wobei die Reguliereinrichtung (35,52,21) des ersten Streckwerks (10) zum Ausgleich von Massenschwankungen anhand der vom Messorgan (32) abgegebenen Signale unter Einbeziehung eines vorgegebenen Sollwertes in den Antrieb des ersten Streckwerks (40) regulierend eingreift.The invention relates to a device for forming a sliver a first, regulated drafting system (10) with several pairs of rollers (11, 12, 14) for controlled stretching of the fiber mass (8) fed to the drafting system, the fiber fleece (28) released by the drafting system is combined and one Measuring element (32) is supplied, from which the measured fiber material subsequently is transferred to a second drafting system (40), the regulating device (35,52,21) of the first drafting system (10) to compensate for mass fluctuations based on the signals emitted by the measuring element (32), including a regulating the specified target value in the drive of the first drafting system (40) intervenes.

In der Praxis sind verschiedene Regel- bzw. Steuereinrichtungen bekannt, um ein qualitativ hochwertiges Faserband zu erhalten. Um kurzwellige und langwellige Massenschwankungen einer vorgelegten Fasermasse einfach zu erfassen und auszugleichen wird eine Vorrichtung vorgeschlagen, wobei das zweite Streckwerk (40) mit einer Steuereinrichtung (35,50,48) zum Ausgleich von kurzwelligen Massenschwankungen versehen ist, welche anhand der vom Messorgan (32) abgegebenen Signale in den Antrieb des zweiten Streckwerks (40) steuernd eingreift.

Figure 00000001
In practice, various regulating and control devices are known in order to obtain a high-quality sliver. In order to easily detect and compensate for short-wave and long-wave mass fluctuations of a fiber mass, the second drafting device (40) is provided with a control device (35, 50, 48) for compensating for short-wave mass fluctuations, which is based on the measurement unit (32 ) emits signals in the drive of the second drafting system (40).
