Sie dienen dazu, ein Faserband zu verstrecken bzw. zu verziehen, wodurch eine Querschnittsreduzierung der Faser bewirkt wird. Während des Verzugs müssen die Fasern möglichst gleichmäßig gegeneinander verschoben werden, um ein gleichmäßiges Faserband zu erreichen, welches Voraussetzung für die Herstellung eines gleichmäßigen Garns ist. Zur Verstreckung des Faserbands weisen die Streckwerke in der Regel mehrere nacheinander angeordnete Walzenpaare auf, die aneinanderliegend angeordnet das zwischen ihnen verlaufende Faserband einklemmen. Ein Walzenpaar besteht dabei üblicherweise aus einer angetriebenen Unterwalze und einer an der Unterwalze anliegenden oberen Druckwalze. Ein Verzug des Faserbands wird dadurch erreicht, dass in der durch die Drehrichtung der Walzenpaare festgelegten Transportrichtung des Faserbands die Umfangsgeschwindigkeit von Walzenpaar zu Walzenpaar zunimmt.Draw frames for spinning machines are known in various designs from the prior art.

Die starre Verbindung des Handhebels mit dem ersten Kniehebel ermöglicht in ergänzender Weise einen einfacheren Aufbau sowie eine kraftsparendere und komfortablere Verstellung der Kniehebelanordnung zwischen der Schließ-und der Öffnungslage. Alternativ dazu ist es denkbar, den Handhebel mit der Kniehebelanordnung mittels Eingriffselementen in Eingriff bringbar vorzusehen, so dass eine Betätigung des Handhebels über die Eingriffselemente, welche den Handhebel mit der Kniehebelanordnung kraftübertragend koppeln, zu einer Betätigung bzw. die Haltestange drehende Bewegung der Kniehebelanordnung führt. Diese alternative Ausgestaltung ermöglicht im Vergleich zu einer starren Verbindung einen zusätzlichen Freiheitsgrad für die konstruktiven Auslegung und Anordnung der die Verstellvorrichtung ausmachenden Komponenten. Die Eingriffselemente können beispielsweise durch eine Aussparung und ein mit der Aussparung zusammenwirkender Steg, Bolzen, Vorsprung oder ähnliches ausgebildet sein, wobei eines der Komponenten aus Handhebel und Kniehebelanordnung die Aussparung und die andere Komponente das mit der Aussparung zusammenwirkende Bauteil aufweist. In diesem Zuge sind auch lösbare Rastverbindungen als Eingriffselemente denkbar.The connection between the hand lever and the toggle lever assembly can be chosen freely within the design conditions. According to a further preferred embodiment of the invention it is provided that the hand lever is pivotable about the first hinge axis together with the first toggle lever. A pivotable mounting of the hand lever to the first hinge axis of the first toggle lever allows a particularly compact and simple structure after it can be dispensed with a further bearing axis for the hand lever. More preferably, the hand lever is rigidly connected to the first toggle lever, in particular integrally formed. The rigid connection of the hand lever with the first toggle lever allows in a complementary manner a simpler structure and a power-saving and more comfortable adjustment of the toggle lever assembly between the closed and the open position. Alternatively, it is conceivable to provide the hand lever with the toggle lever assembly engageable by engaging elements, so that an actuation of the hand lever via the engagement elements, which couple the hand lever with the toggle lever assembly, to a Operation or the support rod rotating movement of the toggle lever assembly leads. This alternative embodiment allows compared to a rigid connection an additional degree of freedom for the structural design and arrangement of the adjusting device constituting components. The engagement elements may be formed for example by a recess and a cooperating with the recess web, bolt, projection or the like, wherein one of the components of the hand lever and toggle assembly has the recess and the other component has the cooperating with the recess component. In this course, releasable locking connections are conceivable as engagement elements.
Kennzeichnend für das erfindungsgemäße Streckwerk ist, dass dieses eine Streckwerkeinheit aufweist, bei der ein oder mehrere Belastungsträger verdrehfest mit einer gemeinsamen Haltestange verbunden sind, die mittels einer Verstellvorrichtung zwischen einer Betriebsposition und einer Öffnungsstellung der Belastungsträger um ihre Längsachse verdrehbar ist. Die Haltestange ist dabei drehbar an einer Haltestangenaufnahme gelagert und erlaubt durch ihre Verdrehbarkeit eine zuverlässige Verstellung und Positionierung aller an der Haltestange angeordneten Belastungsträger. Eine Positionssicherung der Belastungsträger kann zudem zentral über die Verstellvorrichtung erreicht werden, sodass auf einzelne Arretierungen für jeden Belastungsträger verzichtet werden kann. Weitere Ausgestaltungen des Streckwerks ergeben sich aus den vorstehend dargestellten möglichen Weiterbildungen der Streckwerkeinheit.Characteristic of the drafting system according to the invention is that this has a drafting unit, in which one or more load carrier are rotationally connected to a common support rod, which is rotatable about its longitudinal axis by means of an adjusting device between an operating position and an open position of the load carrier. The support rod is rotatably mounted on a support rod receptacle and allows by their rotatability reliable adjustment and positioning of all arranged on the support bar load carrier. A position assurance of the load carrier can also be achieved centrally on the adjustment, so that can be dispensed with individual locks for each load carrier. Further embodiments of the drafting system result from the above possible developments of the drafting unit.

In dem dargestellten Ausführungsbeispiel weist die Streckwerkeinheit 1 zwei parallel zueinander an einer Haltestange 4 angeordnete Belastungsträger 3 mit jeweils einem Tragarm 16 auf, welche jeweils drei aus zwei Druckwalzen 15a, 15b, 15c gebildete Druckwalzenpaare aufweisen, deren Drehachsen senkrecht zur Längsachse des zugeordneten Tragarmes 16 verlaufen. Die Tragarme 16 sind dabei jeweils starr mit zwei beiderseits des Tragarmes 16 angeordneten Stützkörper 17 verbunden, die wiederum verdrehfest mit einer Haltestange 4 verbunden sind (vgl.

Zur Verstellung der Belastungsträger 3 aus der Betriebsposition in die Öffnungsstellung ist eine Verstellvorrichtung 2 vorgesehen, welche den Tragarm 16 gemeinsam mit den mit dem Tragarm 16 verbundenen Stützkörpern 17 um eine Längsachse der Haltestange 4 verschwenkt. Eine Verschwenkung resultiert dabei aus einer Verdrehung der Haltestange 4, welche drehbar an einer Haltestangenaufnahme 5, bspw. einem Maschinengehäuse, gelagert ist. Eine Verdrehung der Haltestange 4 in der Haltestangenaufnahme 5 bewirkt aufgrund der verdrehfesten Anordnung der Stützkörper 17 an der Haltestange 4 eine Verlagerung des Belastungsträgers 3 entsprechend der durch die Verstellvorrichtung bewirkten Drehbewegung der Haltestange 4.For adjusting the
Zur Verstellung der Haltestange 4 weist dabei die Verstellvorrichtung 2 eine Kniehebelanordnung 6 auf, welche mittels eines Handhebels 13 zwischen einer der Betriebsposition zugeordneten Schließlage und einer der Öffnungsstellung zugeordneten Öffnungslage verstellbar ist.To adjust the
Die Kniehebelanordnung 6 weist einen ersten Kniehebel 7 auf, welcher nach einem bevorzugten Ausführungsbeispiel an der Haltestangenaufnahme 5 um eine erste Gelenkachse 9 verschwenkbar ist.

An dem der ersten Gelenkachse 9 gegenüberliegenden Ende ist der erste Kniehebel 7 über eine Kniehebelgelenkachse 11 mit dem zweiten Kniehebel 8 verbunden. Der zweite Kniehebel 8 ist an einem von der Kniehebelgelenkachse 11 beabstandeten Kniehebelabschnitt, in diesem bevorzugten Ausführungsbeispiel an dem der Kniehebelgelenkachse 11 gegenüberliegenden Ende des zweiten Kniehebels 8, über eine zweite Gelenkachse 10 mit einem Lenker 12 verbunden, welcher an dem der zweiten Gelenkachse 10 gegenüberliegenden Ende verdrehfest mit der Haltestange 4 verbunden ist, sodass die Verdrehung des Lenkers 12 eine Verstellung der Haltestange 4 und damit eine Verlagerung des Belastungsträgers 3 bewirkt. Zur Verstellung der Kniehebelanordnung 6 dient ein Handhebel 13, welcher um die erste Gelenkachse 9 verschwenkbar ist und mit der Kniehebelanordnung 6 zusammenwirkt. Nach einem bevorzugten Ausführungsbeispiel ist der Handhebel 13 starr mit dem ersten Kniehebel 7 verbunden, wodurch eine Bewegung des Handhebels 13 unmittelbar zu einer Betätigung des ersten Kniehebels 7 führt. In bevorzugter Weise sind der Handhebel 13 und der erste Kniehebel 7 aus einem Materialstück ausgebildet.
