Die vorliegende Erfindung betrifft ein neues Verfahren und eine dafür geeignete Vorrichtung zur Herstellung von Gardinenbändern mit Ringschleifen, welche aus einem Teile der Bandkette mit Hülfe des einspuligen Bandschusses erzeugt werden.The present invention relates to a new method and an apparatus suitable therefor for the production of curtain tapes with ring loops, which are made from one part of the tape chain can be produced with the aid of the single-reel tape shot.

Nach dem neuen Verfahren, zu dessen Durchführung die Bandkette in an sich bekannter Weise in einzelne Teile zerlegt wird, welche je für sich Fach bilden können, läßt man, solange das Grundband gewebt wird, den Stuhl in der allgemein üblichen Weise arbeiten, die ganze Kette gleichmäßig Fach bilden und den Schuß die Kette ihrer ganzen Breite nach, der jeweils gewünschten Bindung entsprechend, einbinden. Wenn und solange als eine Schlinge gebildet werden soll, setzt man zum Beispiel durch Ausschaltung des! Regulators die eigentliche Abzugsvorrichtung des Stuhls still und hängt dafür in den die Schlingen ergebenden Teil der Kette mechanisch oder von Hand eine geeignete Abzugsvorrichtnng ein, so daß dieser Teil weiter vorrückt, der übrige Teil der Kette aber still steht und kein Gewebeabzug stattfindet.According to the new method, to carry out the belt chain in a known manner Way is broken down into individual parts, each of which can form a compartment for itself, is left as long as it is the base tape is woven, the chair will work in the usual way that entire chain to form evenly shed and the weft of the chain according to its entire width, according to the desired weave, embed. If and for as long as a loop is to be formed, one sets for example by switching off the! Regulator is the actual triggering device of the Chair and hangs mechanically or in the part of the chain that results in the loops manually a suitable extraction device so that this part advances further, the The rest of the chain stands still and no tissue is pulled off.

Ist dieses geschehen, so laßt man nur den die Schlinge ergebenden Teil der Kette Fach bilden und durch den Schuß einbinden, bis eine genügend lange Schlinge gebildet ist.Once this has happened, only the part of the chain that forms the loop is left shed and tie in through the weft until a sufficiently long loop is formed.

Hierauf schaltet man wieder die Abzugsvorrichtung des Stuhls ein und läßt letzteren wieder in der gewöhnlichen Weise arbeiten und das Band in seiner ganzen Breite herstellen, bis die Schlingenbildung von neuem erfolgt.Then you turn on the trigger of the chair again and leave the latter work again in the usual way and make the tape in its full width, until the loop is formed again.

Da während des Webens der Schlingen ein. Abzug des Gewebes nicht stattfindet, so liegen der erste und der letzte Schiingenschuß, welcheAs during the weaving of the loops one. Withdrawal of the tissue does not take place, so lie the first and the last looping shot, which one

zugleich durch das Grundband verlaufen, in diesem unmittelbar nebeneinander, so daß Lücken im Bandgewebe nicht vorhanden sind außer dem unvermeidlichen Schlitz zwischen Ein- und Austritt der Schlinge aus der Bandfläche. ^D at the same time run through the base tape, in this directly next to each other, so that there are no gaps in the tape fabric except for the inevitable slit between the entry and exit of the loop from the tape surface. ^D.

Die zur Ausführung dieses Verfahrens dienende Vorrichtung ist auf der beiliegenden Zeichnung dargestellt. Es zeigen: Fig. 1 den in Betracht kommenden Teil des Stuhls in einem Schnitt in Richtung der Kette während der Herstellung des Grundbandes, Fig. 2 eine Draufsicht -und Fig. 3 eine Vorderansicht zu Fig. i. Fig. 4 ist eine Darstellung wie in Fig. 1, die Herstellung der Schlingen veranschaulichend. · Fig. 5 bis 8 erläutern die Wirkungsweise der Vorrichtung. Fig. 9 bis 12 zeigen ein Stück des fertigen Gewebes bezw. in Seitenansicht, Draufsicht und in zwei Längsschnitten nach den Linien A-A und B-B der Fig. 10.The device used to carry out this process is shown in the accompanying drawing. 1 shows the part of the chair in question in a section in the direction of the chain during the manufacture of the base band, FIG. 2 shows a top view and FIG. 3 shows a front view of FIG. Fig. 4 is a representation as in Fig. 1, illustrating the manufacture of the loops. · Figs. 5 to 8 explain the operation of the device. 9 to 12 show a piece of the finished fabric BEZW. in side view, top view and in two longitudinal sections along the lines AA and BB of FIG. 10.

Im gezeichneten Beispiele ist die Kette in drei Teile^ nämlich die beiden Randteile a b und den die Schlingen bildenden Teil c, welcher in der Mitte oder auch mehr oder weniger rechts oder links (event, auch ganz am Rand) davon angeordnet sein kann. Diese drei Kettenteile sind je in besondere Schäfte 1, 2, 3 eingeschoren und werden von besonderen Spulen entnommen, so daß sie unabhängig voneinander zur Fachbildung durch geeignete Mittel bewegt werden können. Ferner ist Vorsorge dafür getroffen, daß zum Beispiel mittels eines Jacquardzuges der Regulator nach Einlegung einer bestimmten Anzahl von Schüssen, nämlich den zwischen zwei Ringschleifen ins Grundgewebe einzulegenden, selbsttätig ausgeschaltet und nach Fertigstellung der SchlingeIn the example shown, the chain is divided into three parts, namely the two edge parts ab and the loop-forming part c, which can be arranged in the middle or more or less to the right or left (possibly also at the very edge) thereof. These three chain parts are each sheared into special shafts 1, 2, 3 and are removed from special bobbins so that they can be moved independently of one another to form shed by suitable means. Furthermore, provision is made to ensure that, for example by means of a jacquard draw, the regulator is automatically switched off after a certain number of wefts have been inserted, namely those to be inserted into the base fabric between two ring loops, and after the loop has been completed

Claims

is also automatically switched on again, so that the take-off device stands still during the weaving of the loops and no withdrawal of the entire fabric takes place during this time. This facility is not indicated on the drawing, • because it is of a known type and familiar to the weaver. For each aisle of the chair, a hook 6 is held displaceably in the chain direction on the chest tree 4 in the illustrated embodiment in a bar 5, which a pulling device formed by the belt 7 and the weight 8 attached to it tends to pull away from the drawer 9, which effect is limited by a bend 10 located in the hook shaft and resting against the bar 5. The hook end. itself stands horizontally and is shaped so that it can be hooked into the part of the chain that produces the loops. Otherwise, the loom is set up as well known. The mode of operation of the device described in accordance with the new method explained at the beginning is as follows: During the production of the base tape, the chair works in the usual way, the warp forms evenly shed, the weft binds the warp across the entire width and the fabric is pulled off evenly ( Fig. Ι and 2). If a piece of tape is fully woven in this way equal to the loop spacing and a loop is now to be produced, the pull-off device 11 is stopped by switching off the regulator and the regulator no longer pulls off the fabric. At the same time, the shaft movement and thus the shedding is changed in such a way that the first weft α after stopping the trigger only binds one edge part α of the chain and the part c resulting in the loops and then only runs through the latter part of the chain back and forth while the remaining parts of the chain remain in the lower position of the compartment (FIGS. 6 and 7). If a few shots of the loop ribbon to be formed are inserted in this way, the hook 6 is pulled forward against the action of the weight 8 and hung under the chain part c, as can be seen from FIGS. 8 and 9. The hook then serves as a pull-off device for the loop tape fabric, so that the point where the weft is hit always remains the same. ; If the loop tape has the correct length, then when the last loop weft is inserted, the edge part b of the warp forms with a shed, so that it is tied in with the weft β. At the same time, the regulator is switched on again and the withdrawal of the entire tissue begins, that is, the described game is carried out again (FIGS. 10 and 11). - Since the fabric was not pulled off during the manufacture of the loop tape, the two end sections α β of the same, which also each run through a part of the base tape, are in direct contact with one another, so that gap formation is ruled out. The sectional figures 11 and. 12 clearly show the course of the warp and weft threads in the loop and the base fabric. The hook . can either be unhooked from the finished loop by hand or, with a suitable design, it can be done automatically by gradually advancing the finished fabric. The band produced in this way as a simple fabric could still be passed through a folding device underneath the breast tree and thus laid twice. Instead of being divided into three parts, the chain could also be broken down into two parts and the ring loop formed from one edge part. Godparents τ-Α ν Proverbs:

1. Process for the production of curtain tapes with woven ribbon ribbons, in which the chain is divided into several parts, which work in special shafts, so that each part for Shed can form, characterized in that all parts of the chain, as long as none Loop is formed, cooperate and during this time also full deduction of the tape takes place through the regulator, while in the formation of the Ribbon only forms this particular part of the chain, tied in and pulled off for itself, and the other parts of the chain stand still until one

. sufficient loop length is woven, whereupon the whole warp and the haul-off device again work.

2. A device for carrying out the method described in claim 1, characterized in that for each course of the chair on the chest tree (4) a hook (6) is arranged to be pushed back and forth in the direction of the chain, which is inserted into the loop and pulls it off in the direction of the breast tree V15. _;
