Abstract

Die Erfindung bezieht sich auf eine textilverarbeitende Maschine (1) zur Verarbeitung von Textilfasern, wobei das nach der Verarbeitung gebildete Fasergemenge (8) an eine nachfolgende, wenigstens zweistufige Streckwerkseinheit (6) zur Bildung eines gleichmässigen Faserbandes (9) abgeführt wird und zwischen der ersten und zweiten Streckwerksstufe (I, II) ein Messorgan (30) vorgesehen ist, zur Erfassung des nach der ersten Streckwerksstufe (I) zusammengefassten Fasergutes (12) und das vom Messorgan an die Steuereinheit abgegebene Messsignal für den Eingriff in den Antrieb der zweiten Streckwersstufe (II) zum Ausgleich von kurzzeitigen Massenschwankungen im Verhältnis zu vorgegebenen Sollwerten (Soll) herangezogen wird, wobei die durch das Messorgan (30) erfassten langzeitigen Massenschwankungen im Fasergemenge im Bereich hinter dem Messorgan ausgeglichen werden. Um ein qualitativ hochwertiges Faserband zu erhalten und bekannte Einrichtungen zu verbessern, wird vorgeschlagen, dass die Drehzahl des Eingangswalzenpaares (42) der zweiten Streckwerksstufe (II) entsprechend dem Signal des Messorgans (30) gesteuert wird und zwischen den Streckwerksstufen (I, II) ein Faserbandspeicher (3) vorgesehen ist.

Figure 00000001
The invention relates to a textile processing machine (1) for processing textile fibers, the fiber quantity (8) formed after processing being discharged to a subsequent, at least two-stage drafting unit (6) to form a uniform fiber band (9) and between the first and second drafting stage (I, II) a measuring element (30) is provided for detecting the fiber material (12) combined after the first drafting stage (I) and the measurement signal given by the measuring organ to the control unit for intervention in the drive of the second drafting stage ( II) is used to compensate for short-term mass fluctuations in relation to predetermined target values (target), the long-term mass fluctuations in the fiber quantity detected by the measuring element (30) being compensated for in the area behind the measuring element. In order to obtain a high-quality sliver and to improve known devices, it is proposed that the speed of the pair of input rollers (42) of the second drafting stage (II) is controlled in accordance with the signal of the measuring element (30) and between the drafting stages (I, II) Sliver storage (3) is provided.
