Description

Die Erfindung dient dem schonungsvollen Spannen von Fäden aus Glas oder ähnlichem sprödem Material, das einen Betrieb mit einem ebenen Fadenverlauf erfordert, der nicht an den Flanken von konischen Rillen scheuert.The invention serves for the gentle tensioning of threads made of glass or similar brittle material, which is an operation with a flat thread course that does not rub on the flanks of conical grooves.

Der Stand der Technik ist A: der Durchzug des Fadens zwischen zwei elas­ tischen Gummirollen mit einer Preßstelle, die eine hohe Belastung des Materials ergibt. B: die Umschlingung einer rotierenden Magnetbremse mit dem Faden und nachfolgendem schrägen Abzug über eine Hilfsrolle bewirkt Flankenreibung unter Zugkraftwirkung und Schäden am Faden, Abb. 6.The prior art is A: the passage of the thread between two elastic rubber rollers with a press point, which results in a high load on the material. B: Wrapping a rotating magnetic brake with the thread and then pulling it off at an angle using an auxiliary roller causes flank friction under the effect of tension and damage to the thread, Fig. 6.

Erfindungsgemäß wird die unter Zugkraft stehende schräge Ableitung des Fadens 1, Abb. 6, vermieden und in eine schräge, aber kraftlose Zuführung des Fadens 2 umgewandelt (Abb. 2 und 3), bis zur Andruckrolle 3 und Brems­ zylinder 4, der vom Faden 2 umschlungen und in einer Ebene über eine an einem Hebel 5 befindlichen oder feststehenden Rolle 6 unter der einge­ stellten Zugkraft abgezogen wird. Der Anpreßdruck ist von der Zugkraft des Fadens 2 abhängig, so daß eine Zugfeder für die Rolle 3 entfällt, aber zusätzlich verwendet werden kann. Die Kreuzung der Fäden 2-2 a bei x er­ folgt mit einem Abstand zueinander (Abb. 1a). Der unter Zugkraft stehende Fadenverlauf 2 liegt somit in einer Ebene (Abb. zu 2 und 3). In Abbildung 5 ist der Parallelbetrieb mehrerer Fäden über eine Bremseinrichtung darge­ stellt.According to the oblique derivative of the thread 1 , Fig. 6, which is under tensile force, is avoided and converted into an oblique but powerless feed of the thread 2 ( Figs. 2 and 3), up to the pressure roller 3 and brake cylinder 4 , which is from the thread 2 looped and subtracted in one plane via a roller 6 located on a lever 5 or fixed under the tension set. The contact pressure is dependent on the tensile force of the thread 2 , so that a tension spring for the roller 3 is omitted, but can also be used. The crossing of threads 2 - 2 a at x he follows at a distance from each other ( Fig. 1a). The thread course 2, which is under tensile force, thus lies in one plane ( Figs. 2 and 3). Figure 5 shows the parallel operation of several threads using a braking device.

Abb.1 zeigt den Fadenverlauf bis Öse 7 oder Sauschwanz 7 im spannungslosen Zustand bis zur Druckstelle 8 zwischen der Rolle 3 und dem Zylinder 4 der Magnetbremse 9. Ab Öse 7 bis zum Ausgang bei 10 liegt der Faden 2 in einer Ebene, siehe auch Abb. 2 und 3. Die auf einer Hebelverlängerung 11 sitzende Umlenkrolle 6 verstärkt den Druck zwischen den Rollen 3 und 4 in Abhängig­ keit von der eingestellten Fadenzugkraft durch die Magnetbremse 9. Diese Umlenkrolle 6 kann auch feststehend gehalten sein, dann muß der Hebel durch eine Feder 12 auf die Rolle 3 wirken. Fig. 1 shows the course of the thread up to the eyelet 7 or the tail 7 in the de-energized state up to the pressure point 8 between the roller 3 and the cylinder 4 of the magnetic brake 9 . From eyelet 7 to the exit at 10 , the thread 2 lies in one plane, see also Figs. 2 and 3. The deflection roller 6 seated on a lever extension 11 increases the pressure between the rollers 3 and 4 depending on the thread tension set by the Magnetic brake 9 . This deflection roller 6 can also be held stationary, then the lever must act on the roller 3 by a spring 12 .

In Abb. 4 ist die Druckkraft auf 2 Rollen 13-14 verteilt, um die Pressung auf den Faden 2 zu halbieren. Abb. 5 stellt eine mehrfache Belegung einer Bremse mit mehreren parallelen Fäden 2 dar.In Fig. 4, the pressure is distributed over two rollers 13-14 in order to halve the pressure on thread 2 . Fig. 5 shows a multiple assignment of a brake with several parallel threads 2 .
