Durch die hohle Achse 38 reicht ein Glasstab 42 hindurch, der in entsprechender Weise in dieser hohlen Achse 38 festgestellt ist lind gleichmäßig mit den Kohlen 7 und den hohlen Glaszylindern 41 abgenutzt wird. An dem Umfang der Hülsen 40 sind Zahnräder 43 aufgekeilt, welche in die Verzahnung der zentralen Durchlochung der Scheibe ^; eingreifen. Durch Betätigung der Welle 38 werden die Scheiben 39 in Rotation versetzt, wodurch sich die Zahnräder 43 auf der erwähnten Verzahnung der Scheibe T₁J abrollen. Hierdurch wird erzielt, daß gleichzeitig die beiden Kohlen 7 mit den sie umschließenden Glasröhren 41 um den mittleren Glasstab 42 sowie um ihre eigene Achse gedreht werden. Die !einrichtung ist derart getroffen, daß zwischen den Kohlcnstäben 7 ein Flammbogen entsteht, der einerseits die Glasröhren 41 sowie auch den zentralen Glasstab 42 beständig umkreist und dadurch dieselben in vollkommen gleichmäßiger Weise zum Abschmelzen bringt, wobei Wechselstrom angewendet wird, so daß die Kohlenstäbe an ihrer Spitze gleichmäßig und nicht bloß in der Richtung zum Gegenpol abbrennen und durch Abziehen der die Glasfäden erzeugenden Schmelzmasse stetig frei werden. An den Scheiben 39 sind die Kontaktringe 11 angeordnet, von welchen unter Vermittlung vonsSchlciffcdern der Strom in die Kohlenpole geleitet wird. Durch Zusammenstellung mehrerer durch Fig. 1 veranschaulichten Maschinen, welche jedoch derart angeordnet sind, daß deren Achse- 38 konvergierend zueinander und zum Berührungspunkt der Abziehwalzen ge-' stellt sind, wobei nur darauf Rücksicht genommen werden muß, daß sich die einzelnen Maschinen in ihrer Arbeit nicht hindern, kann man Glasgarne mit mehreren parallel laufenden Drähten in einem Zug erzeugen.Λ54fiülserit4o through which, on the one hand, a hollow glass cylinder 41 and, guided through this, a carbon rod 7 or the like are attached. A glass rod 42 extends through the hollow axis 38 and is fixed in a corresponding manner in this hollow axis 38 and is worn evenly with the coals 7 and the hollow glass cylinders 41. On the circumference of the sleeves 40 gears 43 are keyed, which in the toothing of the central perforation of the disc ^; intervention. By actuating the shaft 38, the disks 39 are set in rotation, as a result of which the gears 43 roll on the aforementioned toothing of the disk T ₁ J. This ensures that the two coals 7 with the glass tubes 41 surrounding them are rotated about the central glass rod 42 and about their own axis at the same time. The device is designed in such a way that an arc of flame arises between the carbon rods 7, which on the one hand constantly encircles the glass tubes 41 as well as the central glass rod 42 and thereby melts them in a completely uniform manner, whereby alternating current is used so that the carbon rods on their tip burn evenly and not just in the direction of the opposite pole and are steadily released by pulling off the melt producing the glass threads. The contact rings 11 are arranged on the disks 39, from which the current is conducted into the carbon poles through the intermediary of Schlciffcdern. By combining several machines illustrated in FIG. 1, which are, however, arranged in such a way that their axes are converging to one another and to the point of contact of the peeling rollers, whereby only consideration must be given to the fact that the individual machines work together do not prevent it, you can produce glass yarns with several parallel wires in one go.
