  • This task is the beginning of a device mentioned type in that the feeding device has a second feed path that is separate from the first Feed path through the circumferential wall of the spinning funnel runs.
  • the first and the second feed path 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 form vortices without having to go through more openings to be disturbed in the peripheral wall of the spinning funnel.

You can then add the additional material in a more manageable form, for example in the form of a Sliver or a fleece, up to the dissolving unit transport. There are the fibers of the additional material "isolated”. First the individual fibers or Groups of a few fibers are then over the second Feed path inserted into the spinning funnel.
  • the dissolving unit is in the second feed path directed air flow.

He takes that Additional material from the dissolving unit cleans it So permanently, so that the resolution result constant remains good, it then promotes the fibers of the additional material to the spinning funnel and ensures there is still one better homogenization.
  • the first feed path is advantageously denser the outer wall of the spinning funnel arranged as the second feed path. This simplifies construction.
  • the Spinning funnel or a scraper baffle can still like stay relatively close to the drawing surface before, so that one use the air adhering there to swirl the fibers can.
  • the task is in a method of the aforementioned Art solved in that the additional material is separated from the glass fibers through the peripheral wall in the Room is directed.
  • the additional material is the same Feed opening in a separate from the glass fiber stream Additional material flow directed into the room. With that maintain favorable conditions for swirling.
  • the room has only one defect in its peripheral wall. You can use both materials before the actual swirling bring closer together.
  • the task begins with a fiber composite mentioned type in that the glass fibers and the additional material fibers over the cross section of the fiber composite are mixed largely homogeneously.
  • the fiber composite has the advantage that the homogeneity a stronger resilience possible is. In particular, the risk is drastically reduced that there is local overuse in nests of glass fibers can result in sooner or later lead to damage to the fiber composite.
  • the Hybrid yarn is characterized by a homogeneous blend of the fiber components.
  • thermoplastic Additional materials can use these fibers as a matrix component for that made from the hybrid yarns flat product (e.g. preprep).

This results in better mechanical properties of the end product, especially tensile and bending strength and impact strength.
  • the glass fibers and the additional material fibers are preferred aligned in the main direction of the fiber composite. This results in a relatively high strength.
  • the alignment is of course not exactly parallel. Rather, there are a variety of loops and Loops.
