Allgemeine Beschreibung der ErfindungGeneral description of the invention
Der Erfindung war daher die Aufgabe gestellt, das Einstellen der Maulweite an Doppelriemcheneinrichtungen zu vereinfachen und zu beschleunigen. Sie löst diese Aufgabe durch die im Anspruch 1 genannten Merkmale.Of the Invention was therefore the task of adjusting the jaw width to simplify and accelerate double slip devices. It solves this problem by the mentioned in claim 1 Characteristics.
Mittels der durch eine Feder verstellbar beaufschlagende Belastungsvorrichtung kann der Belastungsdruck auf die Umlenkschiene und damit deren Rückhaltekraft auf den einem Verzug unterliegenden Faserverband an die spinntechnologischen Gegebenheiten angepasst werden. So ist der Belastungsdruck auf die Umlenkschiene bei Faserbänden mit größerer Masse und damit größerer Dicke in der Regel zu vermindern und damit die Maulweite der Riemchenkombination zu erhöhen. In manchen Fällen kann aber auch eine andere Einstellung vorteilhaft sein, etwa bei Fasermaterialien, die ein größeres Rückhaltevermögen haben.through the load device, which is adjustably loaded by a spring can the load pressure on the deflection rail and thus their retention force on the fiber structure subject to a delay to the spinning technological conditions be adjusted. So is the load pressure on the deflection rail in slivers with greater mass and Thus, greater thickness usually decrease and thus to increase the jaw width of the strap combination. In some cases, but also a different attitude be advantageous, such as fiber materials that have a greater retention capacity to have.
Die Belastungsvorrichtung stützt sich vorteilhaft am Pendelarm des Streckwerks ab. Eine einfache und feinfühlige Einstellung der durch den Stößel ausgeübten Belastungskraft auf die Umlenkschiene wird durch ein Stellgewinde in der Belastungsvorrichtung erreicht. Um die Belastungskraft einstellen und die eingestellte Belastungskraft ablesen zu können, wird vorgeschlagen, den Stößel über eine das Stellgewinde aufweisende Hülse hinaus nach oben zu verlängern und mit einer Skala zu versehen.The Loading device is supported advantageously on the pendulum of the drafting system. A simple and sensitive setting the force exerted by the ram loading force on the deflector is by a set screw in the loading device reached. To set the loading force and the set To be able to read the loading force, it is suggested the plunger on a the adjusting thread extending sleeve out upward and to be provided with a scale.
In weiterer Ausgestaltung wird vorgeschlagen, die Umlenkschiene mit zwei, in Faserlaufrichtung beabstandeten Rasten zu versehen, in die der die Belastungskraft übertragende Stößel eingreifen kann. Wenn dazuhin die Abstände der beiden Umlenkkanten der wendbaren Umlenkschiene von den Rasten unterschiedlich gewählt werden, können durch Eingreifen des Stößels in die eine oder die andere Rast und durch Wenden der Unlenkschiene vier unterschiedliche Abstände der Umlenkkante von der Klemmlinie des Riemchenwalzenpaares erreicht werden.In Another embodiment is proposed, the deflection rail with to provide two spaced apart in the direction of fiber travel notches, in that of the loading force transmitting ram can intervene. If in addition the distances of the two deflection edges the reversible deflecting rail chosen differently from the detents can be done by engaging the plunger in one or the other rest and by turning the Unlenkschiene four different distances of the deflection edge from the nip line of the Riemchenwalzenpaares be achieved.
