Die Erfindung betrifft eine Fransendrehmaschine, bei welcher die an den in senkrechter Ebene verstellbaren und hin und her gehenden Drillschienen angeordneten, verschieden gezahnten Kämme durch Verschieben gegeneinander wechselweise in die Arbeitslage gebracht werden können. Bisher wurde stets nur eine einfache Drillschiene ober- und unterhalb des zu drehenden Gewebestreifens verwendet, während die zum Halten der Fäden dienenden Kämme beiderseits der Drillschiene angeordnet waren. Hierbei hat sich der Nachr teil gezeigt, daß die Fäden nicht genügend gedreht werden. Gemäß der Erfindung wird dieser Nachteil dadurch beseitigt, daß die beiden Drilleisten mit je zwei Doppelschienen versehen sind, von denen die beiden oberen beiderseits die in bekannter Weise angeordneten Kämme aufnehmen, während die beiden unteren Drillschienen zwei gegeneinander wechselweise verschiebbare Kämme in sich einschließen. Durch diese Einrichtung werden die zu drehenden Fäden an drei Stellen festgehalten und an zwei Stellen gedreht, wodurch in kürzester Zeit haltbare Fransen erzielt werden.The invention relates to a fringe lathe, in which the at the in vertical Level adjustable and reciprocating drill rails arranged differently Toothed combs alternately brought into the working position by moving them against each other can be. So far there has only been a simple drill bar above and below of the fabric strip to be turned is used, while the combs that are used to hold the threads are on both sides of the twisting bar were arranged. Here the Nachr part has shown that the threads are not enough to be turned around. According to the invention, this disadvantage is eliminated in that the two Drill bars are each provided with two double rails, of which the two upper ones on both sides the combs arranged in a known manner, while the two lower drill rails two combs that can be shifted alternately against each other lock in. Through this device, the threads to be twisted are in three places held and rotated in two places, creating durable fringes in a very short time will.

; Die Erfindung ist in den Fig. 1 bis 3 der Zeichnung im Querschnitt und in Vorder- und Rückansicht veranschaulicht. In den Fig. 2 und 3 ist jeweils nur ein Ende der Drillschienen dargestellt; das andere Ende der Drillschienen ist in derselben Weise ausgebildet. In den Fig. 4 und 5 der Zeichnung sind die Kämme und Drillschienen in Arbeitsstellung im Querschnitt und in Draufsicht dargestellt. .; The invention is shown in Figs. 1 to 3 of the Drawing illustrated in cross section and in front and rear views. In Fig. 2 and FIG. 3 only one end of the twist bars is shown in each case; the other end of the Twist rails is designed in the same way. In Figures 4 and 5 of the drawing are the combs and drill rails shown in the working position in cross-section and in plan view. .

In dem senkrechten Gestell α sind in bekannter Weise die beiden Drilleisten b und c in der Längsrichtung verschiebbar gelagert, während die obere Leiste b auch in senkrechter Ebene verstellbar ist, um die Drillschienen nach erfolgtem Auflegen des Gewebes einander zu nähern. Gemäß der Erfindung sind diese Drilleisten mit je zwei Drillschienen d und f versehen, welche beim Senken der Drilleiste b aufeinander treffen. Beiderseits der oberen Drillschienen d sind in bekannter Weise zwei Kämme oder Kamm-_; paare g und h von verschiedener Zahnweite hintereinander angeordnet und an Riegeln i aufgehängt, welche ein wechsel weises Verschieben der Kämme in die Arbeitslage mittels einer bekannten Schubvorrichtung ermöglichen. Bei der unteren Drilleiste c ist nur ein Kammpaar k und I vorgesehen, und zwar ist dasselbe zwischen den beiden Drillschienen f gelagert. Der Kamm k ist an beiden Enden mit je einem Anschlag m versehen, zwischen welchen sich die Leiste η befindet. Die Leiste η ist mittels Schrauben 0, welche durch die Längsschlitze -p der Drilleiste c greifen, mit einer außerhalb der Drilleiste c befindlichen, am Gestell α befestigten Leiste q verbunden. Durch diese Einrichtung werden die beiden Kämme in der wagerechten Riehtung festgehalten, während ein Hin- und Herbewegen der Drilleiste c ermöglicht wird. Ein Verschieben der Kämme in senkrechterIn the vertical frame α , the two drill bars b and c are mounted displaceably in the longitudinal direction in a known manner, while the upper bar b is also adjustable in the vertical plane in order to bring the drill bars closer to each other after the tissue has been placed. According to the invention, these drill bars are each provided with two drill bars d and f , which meet when the drill bar b is lowered. On both sides of the upper drill rails d are two combs or combs in a known manner _; pairs g and h of different tooth widths arranged one behind the other and suspended from bars i , which allow the combs to be shifted alternately into the working position by means of a known pushing device. In the case of the lower drill bar c, only one pair of combs k and I is provided, namely the same is mounted between the two drill bars f. The comb k is provided at both ends with a stop m , between which the bar η is located. The bar η is connected by means of screws 0, which reach through the longitudinal slots -p of the drill bar c , to a bar q which is located outside the drill bar c and is attached to the frame α. By this device, the two combs are held in the horizontal direction, while a back and forth movement of the drill bar c is made possible. Moving the combs in a vertical position

Claims

Direction is not prevented by the stops m and the bar η. The two combs k, I are alternately moved into the working position by means of a bar r which is provided with inclined slots s. The suspension pegs t and u of the combs I and k engage in these slots. The pin u of the comb k also extends through a vertical slot w of the comb I,

ίο whereby the comb k held by the stops m at the same time also prevents the comb I from shifting in the longitudinal direction. Furthermore, the slot ν enables the two ridges to be displaced relative to one another in the vertical direction. The bar r is connected to a push rod y by means of the bolt w, which engages through the longitudinal slot χ of the drill bar c . The bar r can be moved back and forth by this push rod, the combs mounted in the inclined slots s being alternately raised and lowered.

The described machine works as follows:

After the threads of the fabric strip to be fringed have been clamped in a known manner, the twist bar b is lowered. The threads are divided by the narrow combs g and then twisted together into fringes by means of the twist bars f and d, which move against one another by means of a special drive device. Once this has taken place, the narrow combs are pushed back and the wide combs are advanced by means of the devices already described. The wide ridges are therefore in the working position and always combine two fringes, whereupon the twist bars are shifted again in the opposite direction and the paired fringes are turned into finished fringes.

By the arrangement of double twist bars and the provision of combs between and on both sides of the rails a quick and effective twisting of the fringes is achieved, since the threads are firmly enclosed between the combs and as a result of the double Attack surface of the drill rails no more twist is lost.

The displacement of the combs stored between the double twist rails as well as the Holding the same can also be effected differently from the embodiment shown will.

Pate ν τ-A N SPRU ch:

Fringe lathe with adjustable and reciprocating drill bars, characterized in that each drill bar (b, c) is provided with two drill bars (d, f) lying next to one another, of which the two upper (d) on both sides the combs ( g, h) , while the two lower (f) include two mutually alternately adjustable combs (k, I) so that the threads of the tissue strips to be rotated are held in three places and twisted in two places. ·
