  • the spindle or bobbin element 10 is accordingly (with respect to the direction of fiber guidance) offset laterally relative to the guide elements 5d, 5e associated therewith;
  • the spindle or bobbin element 10 is arranged centrally between the guide elements 5d, 5e assigned to it, although it is spaced apart from the guide elements 5d, 5e in the fiber guide direction.
  • dashed fibers indicate that in principle further fibers (dashed) can also be guided via a respective last guide element 5d, 5e, which, however, belong to another spindle or coil element (not shown), i.e. typically one parallel to the spindle or coil element 10 arranged further spindle or coil element, ie another spinning area, the spinning device 6 are supplied. It is also true for this other spinning area that the fibers to be spun into a yarn 3 there are fed in the same way as in the figures via separate guide elements.
  • 2 shows a schematic diagram of a device 1 for producing a yarn 3 formed by spinning at least two individual fibers 2a, 2b according to a further exemplary embodiment.
  • 2 represents a schematic plan view of the device 1.
  • 4 shows an enlarged view of the in 2 shown detail IV.
  • the spinning of at least three fibers 2a - 2c to form a yarn 3 can, as in the 2 , 4 shown, can be implemented in such a way that at least two fibers 2a, 2c of the spinning device 6 are fed together via a first guide element 5d and at least one further fiber 2b via a further guide element 5e arranged spatially spaced apart from the first guide element 5d. At least two fibers 2a, 2c can thus be fed via a first guide element 5d and at least one further fiber 2b can be fed via a further guide element 5e. In this context, even or uneven distributions of fibers 2a - 2c are possible over a given number of guide elements.
  • exemplary feeding of four fibers (the fourth fiber is indicated by dashed lines) and an exemplary number of two guide elements 5d, 5e, two fibers can be fed via a first guide element 5d and two fibers via a second guide element 5e, or three fibers can be fed via a first guide element 5d and a fiber are fed via a second guide element 5e.
  • the spinning of at least three fibers 2a - 2c according to the method could alternatively also be implemented in such a way that the at least three fibers 2a - 2c are fed to the spinning device 6 via three separate guide elements arranged at a distance from one another in at least one spatial direction by at least one first fiber 2a being fed via a first guide element, at least one second fiber 2b being fed via a second guide element arranged at a spatial distance from the first guide element in at least one and at least one third fiber 2c being fed via a guide element to the second guide element in at least one Spatially spaced arranged third guide element is supplied.
  • Each fiber 2a - 2c can therefore also be fed via a separate guide element.
  • At least two fibers 2a - 2c and at least one filament 17 are spun together to form the yarn 3 .
  • the at least two fibers 2a - 2c and the at least one filament 17 are brought together in the fiber merging point 12 merged. Consequently, yarns 3 can be produced from at least two fibers 2a-2c and at least one filament 17.
  • the spinning of at least two fibers 2a - 2c and at least one filament 17 according to the method can be implemented in such a way that at least two fibers 2a - 2c are fed to the spinning device 6 via two separate guide elements 5d, 5e, which are spaced apart from one another in a spatial direction, and the at least one Filament 17 from a particular coil-like or -shaped, filament storage 18, such as. B. a filament spool, or via a separate third guide element to the two separate guide elements 5d, 5e.
  • guide elements 5d, 5e spatially spaced apart from one another in a spatial direction running transverse to the fiber guidance direction
  • guide elements 5d, 5e it is alternatively or additionally possible, at least in principle, for at least two to be spatially spaced apart from one another in a spatial direction running parallel to the fiber guidance direction arranged guide elements 5d, 5e are used. Consequently, at least in principle, guide elements 5d, 5e that are offset in the fiber guide direction can also be used.
  • fibers 2a, 2b of the same and different chemical and/or geometric and/or physical, in particular mechanical, properties can be spun together to form the yarn 3.
  • All natural fibres e.g. H. e.g. B. alpaca fibres, cotton fibres, cashmere fibres, mohair fibres, silk fibres, linen fibres, wool fibres, in particular new wool fibres, and/or artificial (synthetic) fibres, d. H. e.g. B. plastic fibers, in particular polyamide fibers, polyester fibers, polypropylene fibers, viscose fibers, can be spun together to form the yarn to be produced.
  • mixtures of (one or more) natural fibers and (one or more) artificial fibers are also conceivable.
  • the fibers can be continuous or staple, depending on availability.
  • a (single) fiber 2a, 2b can also be formed from at least two chemically and/or geometrically and/or physically different fiber materials or comprise at least two chemically and/or geometrically and/or physically different fiber materials. A corresponding one can therefore also be designated as a mixed fiber (mixed roving). Fiber 2a, 2b can therefore z. B. from a first fiber material (roving material) and at least one other fiber material (roving material) may be formed.
