  • Publication number: 20260208455
    Abstract: A filament winding method includes at least one filament capture step in which a filament is captured by a filament capturing unit that generates at least one tensile force on the filament and conveys the filament at a first conveying speed, and at least one initial filament winding step, in which the filament is wound onto a winding spool unit. In the filament winding step, the captured filament is brought into contact upstream with the rotated winding spool unit, such that a second conveying speed is exerted on the captured filament. The first and second conveying speeds are of different magnitudes. A ratio of the first and second conveying speeds is selected so the filament forms a loop whose arc points in an entry point direction of the winding spool unit at which the incoming filament provided by a filament generating device meets the winding spool unit.

  • Publication number: 20260200693
    Abstract: A glass fiber winding method for filaments with a thickness of more than 300 tex, preferably for glass fiber direct rovings, comprises at least one filament transfer step, in which the filament that is to be wound is transferred from a winding spool unit onto a further winding spool unit or vice versa, wherein the winding spool units are operated with different outer-circumferential speeds and/or with different revolution speeds at least during the transfer of the filament between the winding spool units, wherein a ratio of the outer-circumferential speeds and/or of the revolution speeds of the winding spool units is selected in such a way that, when the filament is brought into contact with a free winding spool unit of the winding spool units which before the transfer of the filament is free of the filament, the filament forms a loop the arc of which points towards an entry point of the free winding spool unit, at which the incoming filament meets the free winding spool unit, wherein the formation of the loo

  • Patent number: 9845221
    Abstract: A winding device for winding a material to be wound includes a winding mandrel provided for carrying a carrier of material to be wound in a winding process, with a transporting unit on which at least a component of the winding mandrel is arranged, and with a positioning unit provided for changing a spatial position of the transporting unit. The positioning unit is provided for at least substantially adjusting a spatial end position according to requirement. The transporting unit is embodied as a pivot arm, the transporting unit is in at least one operating state provided for receiving a carrier of material to be wound, wherein the material to be wound is wound onto the carrier of material to be wound and/or is wound off the carrier of material to be wound, and the transporting unit is in the winding operative position during the winding process.
