Description

Walzenstreckwerk. Die Erfindung betrifft Walzenstreckwerke, bei denen auf dem Unterzylinder des mittleren Walzenpaares ein besonderes Faserführungsglied vorgesehen ist. Es sind Streckwerke dieser Art bekannt, bei denen das Faserführungsglied aus einer Achse und einer auswechselbaren. Gleithülse besteht. Diese Anordnung hat den Zweck, das Hülsengewicht unter Beibehaltung des Durchmessers zu verändern. Ferner hat man auch vorgeschlagen, vor den Lieferwalzen eine besondere kleine Unterwalze vorzusehen, über der ein Belastungskörper angeordnet ist.Roller drafting system. The invention relates to roller drawing units in which a special fiber guide member on the lower cylinder of the middle pair of rollers is provided. Drafting systems of this type are known in which the fiber guide member from an axis and an interchangeable one. There is sliding sleeve. This arrangement has the purpose of changing the case weight while maintaining the diameter. Further it has also been proposed to have a special small lower roller in front of the delivery rollers provide over which a load body is arranged.

Von den bekannten Anordnungen unterscheidet sich der Gegenstand der Erfindung dadurch, daß der Unterzylinder des mittleren Walzenpaares auswechselbare Hülsen von verschiedenem Außendurchmesser besitzt, die den verschiedenen Faserlängen derart angepaßt und aufschiebbar sind, daß im Streckfeld der freie Raum zwischen Vorder-, Mittel- - und Hinterzylinder der jeweiligen mittleren Faserlänge entsprechend ausgefüllt wird.The subject matter of the differs from the known arrangements Invention in that the lower cylinder of the middle pair of rollers is interchangeable Has sleeves of different outer diameters, which correspond to the different fiber lengths are adapted and postponed in such a way that the free space between Front, middle and rear cylinders according to the respective mean fiber length is filled out.

Auf der Zeichnung-ist der Gegenstand der Erfindung beispielsweise im Querschnitt schematisch dargestellt.In the drawing, the subject matter of the invention is for example shown schematically in cross section.

Die Zylinder i, 2 und 5 sind wie bei den bekannten Streckwerken ausgebildet. Der Zylinder 2 besitzt eine auswechselbare Hülse 3 mit einem Lederüberzug 4. In unmittelbarer Nähe der Hülse 3 ist eine Führung 8 angeordnet, die in dem dargestellten Ausführungsbeispiel die Form eines Bleches hat. Diese Führung kann aber auch aus einer kleinen Walze bestehen. 6, 9 und io sind die zu den Zylindern 5 bzw. i gehörigen Druckwalzen; oberhalb des Zylinders 2 ist ein geriffelter Druckzylinder 7 angeordnet.The cylinders i, 2 and 5 are designed as in the known drafting systems. The cylinder 2 has an exchangeable sleeve 3 with a leather cover 4. In In the immediate vicinity of the sleeve 3, a guide 8 is arranged, which in the illustrated Embodiment has the shape of a sheet. However, this tour can also consist of consist of a small roller. 6, 9 and io are those associated with cylinders 5 and i, respectively Pressure rollers; A corrugated pressure cylinder 7 is arranged above the cylinder 2.

Durch .den Zylinder mit -der Hülse 3, 4 und die Führung 8 wird das Vorgarn vom hinteren Zylinder 5 zu dem vordersten Zylinder i in getragenem und gehaltenem Zustand so nahe herangebracht, daß auch die kürzesten Faserchen gefaßt und gleichmäßig verteilt werden können. Je nach der Länge und Beschaffenheit der Fasern können verschiedene Hülsen auf den Zylinder 2 aufgeschoben werden.Through the cylinder with the sleeve 3, 4 and the guide 8 the Roving from the rear cylinder 5 to the foremost cylinder i in carried and held Condition brought so close that even the shortest fibers are collected and evenly can be distributed. Depending on the length and nature of the fibers, different Sleeves are pushed onto the cylinder 2.
