There is also an order facility intended for fibers made of a different material, the synthetic fibers in place on the drawing surface applies the glass threads on the drawing surface. Alternatively, the application of the synthetic fibers also at the collection point of the glass threads or on the piece between this delivery point and the entrance into the spinning funnel.
  • EP 0 616 055 B1 shows a method and a device for producing a composite yarn, in which endless glass filaments are connected to endless filaments made of thermoplastic organic material. For this purpose, the individual glass filaments are passed through a coating device.

  • the first and second feed paths preferably run through the feed opening and are through a partition separated from each other. Accordingly, are opposite only minor changes in the conventional device necessary. Basically, it's enough to get one Insert the sheet into the feed opening on the underside the glass fibers run in and on the top the fibers of the additional material. The swirling takes place then in the spinning funnel, where the corresponding ones are Can develop vortices; without through further openings to be disturbed in the peripheral wall of the spinning funnel.
