Die Erfindung betrifft eine Schußfadenspeichervorrichtung für Webmaschinen, mit einem Fadenmitnehmer mit Fadenführer zum Ablegen des Schußfadens in Form einer Schlaufe auf mindestens einen Teil des Außenumfanges eines gekrümmten Fadenträgers.The invention relates to a weft thread storage device for weaving machines, with a thread driver with thread guide for depositing the weft thread in the form of a loop on at least part of the Outer circumference of a curved thread carrier.

Eine bekannte Vorrichtung (DE-OS 21 17 705) dieser Art weist den Nachteil auf, daß die Zeit zur Speicherung des Schußfadens nur 180° einer Umdrehung der Hauptwelle der Webmaschine beträgt. Die Zeit für die Eintragung beträgt somit auch 180°. Anstrebenswert ist jedoch manchmal eine etwas kürzere Eintragszeit, da dann die Verweilzeit des Rietes mit den Fadentransportdüsen im Webfach gleichermaßen kürzer sein kann. Dies ist günstiger für den Bewegungsablauf des Rietanschlages.A known device (DE-OS 21 17 705) of this type has the disadvantage that the time for storage of the weft thread is only 180 ° one revolution of the main shaft of the loom. The time for that Entry is therefore also 180 °. However, a somewhat shorter entry time is sometimes desirable because then the dwell time of the reed with the thread transport nozzles in the shed can be equally shorter. This is more favorable for the sequence of movements of the reed stop.

Der Erfindung liegt die Aufgabe zugrunde, eine Schußfadenspeichervorrichtung der eingangs definierten Art zu schaffen, die eine Speicherzeit von mehr als 180° erlaubt. Gemäß der Erfindung sind zur Lösung dieser Aufgabe die im kennzeichnenden Teil des Anspruchs angegebenen Gestaltungsmerkmale vorgesehen. The invention is based on the object of providing a weft thread storage device of the type defined at the outset Kind of creating that allows a storage time of more than 180 °. According to the invention are to the solution this task provided the design features specified in the characterizing part of the claim.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist nachstehend anhand der Zeichnung beschrieben. Die einzige Figur der Zeichnung zeigt eine Schußfadenspeichervorrichtung gemäß der Erfindung in schematischer Darstellung.An exemplary embodiment of the subject matter of the invention is described below with reference to the drawing. the The only figure of the drawing shows a weft storage device according to the invention in schematic form Depiction.

Der Fadenspeicher weist einen Fadenmitnehmer in Form eines endlosen, dreieckig aufgespannten Bandes 75 auf, das von drei Rollen 76,77 und 78 geführt ist. Eine der Rollen ist angetrieben. Das Band ist versehen mit einer Fadenöse 79, die in einem Schußfaden 80 eine Schlaufe 81 mit Schenkeln 81' und 82" bildet. Zwei Rollen 82 und 83 mit einer V-förmigen Vertiefung 84 bzw. 85 dienen als Fadenträger für den Schenkel 81' bzw. 8i". Die Rollen 82 und 83 sind auf einem Schwenkarm 86 angeordnet, der in einem Lager 87 drehbar gelagert ist. Nachdem das Band 75 die Schlaufe 81 zur erforderlichen Länge ausgebildet hat, wird der Schwenkarm 80 im Uhrzeigersinn in die Lage 86' gedreht, so daß die Schlaufe abgeführt und über eine Eintragstrommel 88, eine Bremse 89 und eine Eintragsdüse 90 dem Webfach zugeführt werden kann. The thread store has a thread driver in the form of an endless, triangular stretched belt 75, which is guided by three rollers 76,77 and 78. One of the rollers is driven. The band is provided with a thread eyelet 79 which forms a loop 81 with legs 81 'and 82 "in a weft thread 80. Two Rollers 82 and 83 with a V-shaped recess 84 and 85 serve as thread carriers for the leg 81 ' and 8i ". The rollers 82 and 83 are arranged on a pivot arm 86 which is in a bearing 87 is rotatably mounted. After the tape 75 has formed the loop 81 to the required length, the Swivel arm 80 is rotated clockwise into position 86 'so that the loop is removed and over a Entry drum 88, a brake 89 and an entry nozzle 90 can be fed to the shed.

Selbstverständlich braucht der Fadenmitnehmer nicht als Dreieck gestaltet zu sein, sondern kann auch eine andere Kontur, z. B. die eines Vielecks haben.Of course, the thread driver does not need to be designed as a triangle, but can also be one other contour, e.g. B. have that of a polygon.

Obschon der Erfindungsgegenstand hier für eine Webmaschine mit Lufteintrag beschrieben wurde, ist er auch für andere Webmaschinen geeignet, z. B. für eine Greiferprojektil-Webmaschine.Although the subject matter of the invention has been described here for an air-fed loom, it is also suitable for other weaving machines, e.g. B. for a rapier projectile loom.
