Description

Fadenspanner zur Verarbeitung von sprödem Fadenmaterial wie z. B. von Kohlenstoff- oder Glasfasern mit geringster Belastung des Fadens.Thread tensioner for processing brittle thread material such. B. from Carbon or glass fibers with minimal strain on the thread.

Es sind magnetische Fadenspanner bekannt (auch Fadenbremsen genannt), die einen praktisch geraden Fadendurchlauf besitzen zwischen der Bremsrolle 1 und einer elastischen Andrückrolle 2. Der kurze Berührungsweg an der Quetschstelle 3 erfordert eine verhältnismäßig hohe Anpreßkraft zwischen den beiden Rollen 1 und 2, da auch zusätzlich eine erhebliche Walkarbeit überwunden werden muß.Magnetic thread tensioners (also called thread brakes) are known which have a practically straight thread passage between the brake roller 1 and an elastic pressure roller 2 . The short contact path at the pinch point 3 requires a relatively high contact force between the two rollers 1 and 2 , since considerable flexing work must also be overcome.

Eine dritte Umlenkrolle 4 mit einer nach vorn geneigten Achse 5 ermöglicht es, daß der zu spannende spröde Faden 6′ ohne auf den glatten Rollen (ohne Rillen) seitlich zu rutschen, ein zweites oder mehrfaches Mal zwischen das Rollenpaar 1 und 2 geführt wird und zwar mit geringer paralleler Versetzung 7 zum ersten Einlauf des Fadens 6, bei nur etwa einem Zehntel der Anpreßkraft gegenüber dem nur einmaligen Durchlauf. Das äußert sich schonend für die spröde Faden­ struktur.A third deflecting roller 4 with a forwardly inclined axis 5 enables the brittle thread 6 to be tensioned to be moved laterally without slipping on the smooth rollers (without grooves) a second or several times between the pair of rollers 1 and 2 , specifically with a small parallel offset 7 to the first entry of the thread 6 , with only about a tenth of the contact pressure compared to the only one pass. This is gentle on the brittle thread structure.

Die Achse 5 der Umlenkrolle 4 steht etwa rechtwinklig zum Fadenverlauf zwischen den Rollen 1 und 4. Die Größe des Winkels 8 ist für den Abstand 7 der beiden Fäden 6 und 6′ zwischen den Rollen 1 und 2 maßgebend (Abb. 3). Sie ist auch abhängig von dem Rollenabstand und deren Durchmesser.The axis 5 of the deflection roller 4 is approximately at right angles to the course of the thread between the rollers 1 and 4 . The size of the angle 8 is decisive for the distance 7 of the two threads 6 and 6 ' between the rollers 1 and 2 ( Fig. 3). It also depends on the roller spacing and its diameter.

Claims (4)

1. Fadenspanner, insbesondere für sprödes Material, wie z. B. Kohlenstoffasern, dadurch gekennzeichnet, daß der Faden (6) über eine zusätzliche Rolle (4) mit schrägstehender Achse (5) ein zweites Mal, parallel zum ersten Ein­ lauf, zwischen die magnetische Bremsrolle (1) und die elastische Anpreß­ rolle (2) geführt wird, so daß der auslaufende Faden (6′) etwa in gleicher Zugrichtung wie der einlaufende (6) verläuft.1. Thread tensioner, especially for brittle material, such as. B. carbon fibers, characterized in that the thread ( 6 ) via an additional roller ( 4 ) with an inclined axis ( 5 ) runs a second time, parallel to the first one, between the magnetic brake roller ( 1 ) and the elastic pressure roller ( 2nd ) is guided so that the outgoing thread ( 6 ' ) runs approximately in the same direction as the incoming ( 6 ). 2. Fadenspanner nach Anspruch 1, dadurch gekennzeichnet, daß die Neigung der Umlenkrollenachse (5) etwa im rechten Winkel zum Fadenteil zwischen Bremsrolle (1) und Umlenkrolle (4) steht, (Abb. 1).2. Thread tensioner according to claim 1, characterized in that the inclination of the deflection roller axis ( 5 ) is approximately at right angles to the thread part between the brake roller ( 1 ) and deflection roller ( 4 ), ( Fig. 1). 3. Fadenspanner nach Anspruch 1 und 2, dadurch gekennzeichnet, daß durch die Größe dieses Neigungswinkels (8) der parallele Abstand (7) der Fäden (6) und (6′) zwischen den beiden Rollen (1) und (2) festgelegt wird (Abb. 2).3. Thread tensioner according to claim 1 and 2, characterized in that the parallel distance ( 7 ) of the threads ( 6 ) and ( 6 ' ) between the two rollers ( 1 ) and ( 2 ) is determined by the size of this angle of inclination ( 8 ) ( Fig. 2). 4. Fadenspanner nach Anspruch 1 bis 3, dadurch gekennzeichnet, daß durch die halbseitige Umschlingung der Bremsrolle (1) die Adhäsion des Fadens (6) soweit erhöht wird, daß die Anpreßkraft zwischen den beiden Rollen (1) und (2) erheblich vermindert werden kann.4. Thread tensioner according to claim 1 to 3, characterized in that the adhesion of the thread ( 6 ) is increased to such an extent that the contact force between the two rollers ( 1 ) and ( 2 ) is considerably reduced by the half-sided wrap of the brake roller ( 1 ) can.
