Description

Es sind Fadenspannvorrichtungeü bekannt, bei denen der Faden durch rechen- oder zahnstangenartig ineinandergreifende Teile geführt ist. Eine Regelung der Fadenspannung erfolgte dadurch, daß die beiden ineinandergreifenden Teile mehr oder weniger belastet wurden. Hierdurch wurde im wesentlichen die Reibung des Fadens durch den Druck der beiden Teile aufeinander geändert. Eine Änderung des Umschlingungswinkels des Fadens erfolgte nur in geringem Ausmaße. There are Fadenspannvorrichtungeü known in which the thread through Rake-like or rack-like interlocking parts is performed. A scheme the thread tension was done by the fact that the two interlocking parts more or were burdened less. This essentially reduced the friction of the thread changed by the pressure of the two parts on each other. A change in the wrap angle of the thread took place only to a small extent.

Die Regelung derartiger Fadenspannvorrichtungen bzw. Fadenbremsen war nur durch besonderen Aufwand möglich und somit nachteilig. Es mußte eine besondere Einstellvorrichtung, bestehend aus einem Hebelgestänge mit Rastanordnung verwendet werden.The regulation of such thread tensioning devices or thread brakes was only possible with special effort and therefore disadvantageous. It had to be a special one Adjusting device consisting of a lever linkage with a locking arrangement used will.

Die Erfindung hat sich die Aufgabe gestellt, die Regelung derartiger Fadenspannvorrichtungen besonders einfach zu gestalten, adern die beiden rechen-oder zahnstangenartig ineinandergreifenden Teile in ihrem Abstand voneinander durch eine Exzenterscheibe leicht regelbar sind, die unmittelbar den beweglichen rechenartigen Teil betätigt. Hierfür dient in einfachster Weise die für die Befestigung von Fadenführern im Scherrahmen verwendeten Befestigungsscheiben. Eine solche Befestigungsscheibe, die beispielsweise aus Gummi besteht, wird als Exzenterscheibe ausgebildet, so daß durch ihre Drehung der eine Teil des Fadenspanners mehr oder weniger abgehoben wird. The invention has the task of regulating such To make thread tensioning devices particularly easy, the two rake or veins Rack-like interlocking parts in their distance from one another by a Eccentric disc are easily adjustable, which directly the movable rake-like Part operated. The simplest way to do this is to attach thread guides mounting washers used in the shear frame. Such a fastening washer, which consists, for example, of rubber, is designed as an eccentric so that by turning one part of the thread tensioner is more or less lifted off.

In den Fig. I bis 3 ist ein Ausführungsbeispiel der Erfindung dargestellt. Fig. r zeigt eine Vorrichtung I mit den beiden Fadenführern 2 und 3, zwischen denen der aus den beiden rechenartig ausgebildeten Teilen 4 und 5 bestehende Fadenspanner angeordnet ist. Der Faden 6 läuft durch die beiden rechen- bzw. zahnstangenartig ausgebildeten Teile 4 und 5 hindurch und wird, je nach dem Abstand dieser Teile und des hierdurch bedingten Umschlingungswinkels, mehr oder weniger abgebremst bzw. gespannt. Die Fadenführer 2 und 3 sind durch Gummischeiben 7 und 8 im Scherrahmen I festgehalten. In Figs. I to 3, an embodiment of the invention is shown. Fig. R shows a device I with the two thread guides 2 and 3, between which the thread tensioner consisting of the two rake-like parts 4 and 5 is arranged. The thread 6 runs through the two like a rake or rack formed parts 4 and 5 through and is, depending on the distance between these parts and the resulting wrap angle, more or less braked or tense. The thread guides 2 and 3 are through rubber washers 7 and 8 in the shear frame I held on.

Gemäß der Erfindung ist die eine Gummischeibe'8 als Exzenterscheibe ausgebildet und dient dazu, wie Fig. 2 und 3 erkennen lassen, den Teil 4 des Fadenspanners anzuheben. Je nachdem in welche Stellung die Exzenterscheibe gedreht wird, wird der Umschlingungswinkel des Fadens 6 in einfachster Weise geändert, und es kann schnellstens die jeweilig erforderliche Fadenspannung eingestellt werden. According to the invention, there is a rubber disk 8 as an eccentric disk formed and serves, as can be seen in FIGS. 2 and 3, the part 4 of the thread tensioner to raise. Depending on the position in which the eccentric disc is rotated, the angle of wrap of the thread 6 changed in the simplest way, and it can the required thread tension can be set as quickly as possible.

PATENTANSPRtTCHE I. Fadenspannvorrichtung, insbesondere bei Schermaschinen, bei der rechen- uni zahnstangenartig ineinandergreifende Teile der Fadenbremse in ihrem Abstand voneinander regelbar sind, dadurch gekennzeichnet, daß der Abstand der beiden rechen- oder zahnstangenartig ineinandergreifenden Teile durch eine Exzenterscheibe regelbar ist, die unmittelbar den beweglichen rechenartigen Teil der Fadenbremse betätigt. PATENT CLAIMS I. Thread tensioning device, especially for shearing machines, at the rake uni parts of the thread brake that mesh like a rack in their distance from one another can be regulated, characterized in that the distance of the two rake-like or rack-like interlocking parts by an eccentric disk is adjustable, which directly affects the movable rake-like part of the thread brake actuated.
