This is from outside the winding machine and delivery device for textile machines with body illuminated by means of a light source. the Infrequent thread consumption, such as knitting and amount of hitting the photo resistor. Knitting machines, with a bobbin, on which light is loaded by the size of the thread reserve ^ #er thread to form a thread supply is correct tangentially 5, which is in the translucent part of the Can be wound up and from which the thread extends axially removable into the winding body. When falling below is, with your winding body a scanning control a certain amount of light as a result of reaching Filling with movable, through openings of the winder a maximum supply is the drive of the Jceikcrpers is assigned to arms reaching through, winding body stopped electrically, iiie by swiveling the arms under the wir- io while increasing the light intensity as a result Rurig of the thread supply when a limit is exceeded before the transparent part is released by the certain maximum amount of thread supply the decreasing thread supply of the drive again The winding process is interrupted or slowed down and when switched on wirrl. It is constructively difficult to im Falling below a predetermined minimum thread inside the bobbin a folo resistance amount of quantity starts the winding process or accommodates 15 and precisely for this it is adjusted out of acceleration, to arrange a light source half of the bobbin.

Bei einer bekannten Vorrichtung dieser Art Die Genauigkeit der Aibeitsweise wird außerdem da-(schweizerische Patentschrift 374 345) sind die Arme durch beeinträchtigt, daß der Lichtstrom durch den als Winkelarme ausgebildet, deren äußeire Winkel- sich auf- und abspulenden Faden nicht vollkommen abschnitte im wesentlichen radial zur Umfangsfläche ao exakt und in jederzeit vorhersehbarer Weise belies Wickelkörpers beweglich sind. Diese den Faden einflußt wird. Außerdem kann die Lichtquelle durch aufnehmende Umfangsfläche wird durch eine Anzahl Faserflug beeinträchtigt werden, so daß das Meßvon in Winkelabständen angeordneten Riementrieben ergebnis verfälscht wird.In the case of a known device of this type, the accuracy of the method is also used (Swiss Patent 374 345) are affected by the fact that the light flux through the arms designed as angled arms, the äußeire angular winding and unwinding thread is not perfect sections essentially radially to the circumferential surface ao exactly and in a manner predictable at all times Winding body are movable. This influences the thread. In addition, the light source can come through receiving circumferential surface will be affected by a number of fiber fly, so that the measurement of Belt drives arranged at angular intervals are falsified.

Erreicht die Wickellage eine bestimmte, gemäß dadurch gelöst, daß die Anne durch Ausder maximalen Fadenvorratsmenge entsprechende 30 bildung an einer im Wickelkörper um eine zu dessen Länge, dann · werden die Winkelarme durch die Achse querverlaufende Schwenkachse kippbaren, Wickeüage nach innen in den Wickelkörper hinein- durch einen Kraftspeicher in eine Schrägstellunp gegeschwenkt.

The angled arms reach outward between the type of drive described at the beginning. The winding layer th that it is simple in structure and function and is reliably operated by the belt drives on the angle arms. This task is pushed to the invention. If the winding position reaches a certain, according to the fact that the anne, corresponding to the maximum amount of thread supply, is formed on one in the winding body by one to its length, then swiveled into an inclined position by an energy storage mechanism. This pivoting movement is supported by a forced disk on the thread reserve essentially linkage on a clutch or brake transmitted in the axial direction of the bobbin and requires the drive of the bobbin as a result of the thread reserve building up. Conversely, after the thread supply on the upper of the belt drives, which is below the minimum amount of thread, slides away from the minimum amount of thread, the angle levers are again free to pivot radially outwards to the surface of the bobbin in the other sense. essentially in the axial direction of the bobbin speed of the bobbin is again srhöhl. <o are pivotable, and that the disk at Da the scanning of their pivoting movement formed by the angle arms acts on a switching element elements of the scanning control device in the known.
