Description

Herstellung von nahtlosen Karkassen für Wulstfahrradreifen. Die Erfindung betrifft ein Verfahren zur Herstellung von nahtlosen Karkassen für Wulstfahrradreifen, bei dem die Karkassengrundlage, Kanevas, Leinwand o. dgl. schraubenförmig um die Achse gewickelt wird.Manufacture of seamless carcasses for tubular bicycles. The invention relates to a process for the production of seamless carcasses for bead bicycle tires, in which the carcass base, canvas, canvas or the like helically around the Axis is wound.

Das Neue besteht darin, daß die Gummiwülste vor dem Wickeln in zwei in eine Achse eingearbeitete Längsnuten gelegt und nach dem Wickeln mit dem Karkassenschlauch von der Achse abgezogen werden, worauf durch Zusammendrücken des schlauchförmigen Gebildes eine nahtlose Karkasse mit eingebetteten Gummiwülsten entsteht. Die Vorzüge der nahtlosen Karkassen gemäß der Erfindung sind große Biegsamkeit, saubere Herstellungsmöglichkeit und große Festigkeit.The novelty is that the rubber beads are cut in two before winding longitudinal grooves worked into an axis and after winding with the carcass tube be pulled off the axle, whereupon by squeezing the tubular The result is a seamless carcass with embedded rubber beads. The advantages of the seamless carcasses according to the invention are great flexibility, clean manufacturing possibility and great strength.

Zur Ausführung des Verfahrens kann man sich einer Vorrichtung bedienen, wie sie in der beliegenden Zeichnung,beispielsweise dargestellt ist.A device can be used to carry out the process, as shown in the accompanying drawing, for example.

Abb. i zeigt die Gesamtvorrichtung in Ansieht.Fig. I shows the overall device in view.

-Abb.:2 zeigt einen Schnitt nach der Linie :2-2 der Abb. i in vergrößteirtem Maßstabe. Abb. 3 icigt die fertiggewickelte I-'-ukasse in dem Augenblick, wie sie von der Vorrichtung abgezogen ist.- Fig. 2 shows a section along the line: 2-2 of Fig. I on an enlarged scale. Fig. 3 icigt the fully wound I -'- ukasse at the moment when it is removed from the device.

Abb. 4 zeigt die Karkasse in fertigem Zustande.Fig. 4 shows the carcass in its finished state.

Zum Wickeln der Karkasse ist eine Achse a vorgesehen, in welche in der Längsrichtung einander gegenüber zwei Einschnitte b eingearbeitet sind, die zur Aufnahme der Gummiwulste c dienen.For winding the carcass, an axis a is provided, in which two incisions b are machined opposite one another in the longitudinal direction and serve to receive the rubber beads c.

Parallel der Achse a ist eine steilgängige Schraubenspindel d mit Mutter e vorgesehen. Letztere trägt eine Welle f, von der die Karkassenleinwand g o. dgl. abgewickelt wird. A steep screw spindle d with nut e is provided parallel to the axis a. The latter carries a shaft f from which the carcass canvas g or the like is unwound.

Spindel d und Achse a werden gleichzeitig angetrieben.Spindle d and axis a are driven simultaneously.

Es spielt sich nun folgender V6rgalig ab: Wird die Vorrichtung in Bewegung gesetzt, so wickelt sich von der Rolle f die in bekannter Weise gummierte Karkassenleinwand g in einem Winkel von -45' selbsttätig auf die Achse a auf und umhüllt hierbei die in diese eingelegten Gummiwülste c.The following basically happens: If the device is set in motion, the carcass canvas g, which is rubberized in a known manner, automatically winds from the roller f at an angle of -45 'onto the axis a and in doing so envelops the rubber beads inserted into it c.

Ist die ganze Achse a umwickelt, so wird die entstandene zylindrische Hülle gemeinsam mit den init ihr verklebten Gummiwülsten c von der Achse a abgezogen.If the whole axis a is wrapped around, the resulting cylindrical one The envelope is pulled off the axis a together with the rubber beads c bonded to it.

Der zylindrischen Hülle wird dann in geeigneter Weise die Karkassenform gegeben, z> nachdem sie zuvor (Abb. 4) zusammengedrückt worden ist.The cylindrical shell is then placed in a suitable way the carcass shape, z> after it has been compressed previously (Fig. 4).
