Definitions
- the invention relates to a method and a device for the production of core yarn or core slip.
- at least one fiber ribbon is combined with at least one filament and twisted, the fiber ribbon being subjected to a compression process before the twist is given.
- the invention is therefore based on the object of providing a method and a device for producing core yarn or core shorts which enable a filament to be embedded to a high degree in a technically uncomplicated manner.
- An important advantage of the invention is that the filament is fed to the fiber ribbon with a defined tension after the compression zone. It is fed in the simplest way using a thread guide.
- FIG. 1 is a side view of a device according to the invention with a drafting device, a compression unit and a ring spinning unit,
- Fig. 2 is a plan view of parts of the drafting system and the compression unit and in
- FIG. 3 shows a detail from FIG. 2.
- the invention is based on the production of core slip, in which two fiber tapes and a filament are used as the core thread be united and provided with a rotation.
- the invention can also be used for the production of core yarn from a fiber ribbon and a filament or for other numerical combinations of fiber ribbons and filaments.
- Fig. 1 shows a drafting system 1 as it is used on ring spinning machines.
- the lower roller 4 and the upper roller 8 together form the output roller pair 4; 8 of the drafting unit 1.
- This suction element 10 and a guide roller 11 are each partially wrapped around by an air-permeable conveyor belt 12.
- the guide roller 11 bears against a drive roller 13 which is connected to a motor drive in a manner not shown.
- This drive roller 13 is preferably like the lower rollers 2; 3; 4 Part of a drive shaft that extends over several spinning positions or over the entire length of the machine.
- the guide roller 11 is pressed against the drive roller 13 by means of a spring 14 which is fastened to a holding bracket 15 which is connected to the spinning frame.
- the conveyor belt 12 and the fiber ribbon 9 resting thereon are also held on the surface of the suction element 10 by a clamping roller 16.
- the drafting unit 1 with the compression unit 10-16 is followed by a conventional ring spinning device 17, the elements of which need not be explained in more detail here.
- a filament supply 18 (preferably a spool) with a filament 19, which serves as the core thread for the core yarn to be produced or the core slip.
- This filament 19 can for example be a yarn, a mono- fil, an elastane thread, a metallized plastic filament or a metal thread.
- two fiber ribbons 9 guided parallel to one another in the drafting device 1 can be seen.
- the fiber ribbons 9 are first compressed and then the filament 19 is fed from the filament supply 18.
- the filament 19 is taken off by the clamping roller 16.
- the design of the suction element 10 according to the invention is also of importance for the manufacture of core shine shown in FIG. 2.
- the suction element 9 contains a suction slit 21 which runs obliquely to the running direction 20 of the fiber ribbon 9.
- the two suction slits 21 are set such that they run towards one another in the direction of travel 21 in a V-shape.
- the fiber ribbons 9 are thus guided at a sufficient distance on the inlet side, which prevents fibers from jumping over between the fiber ribbons 9.
- the fiber tapes 9 only approach each other after the fibers have been taken over by the compression device. In the case of worsted yarn in particular, this can additionally be arranged by arranging a Siro main field compressor 22 in front of the output roller pair 4; 8 are supported (see Fig. 1).
- This V-shaped arrangement of the suction slots 21 is also responsible for the already mentioned fact that the two fiber tapes 9 still move at a distance from one another in the nip line on the nip roller 16. So that's it Possibility given to also feed the filament 19 so that it still passes this nip at a distance from the fiber ribbon 9. It has proven to be particularly advantageous if the filament 19 is fed centrally between the fiber ribbons 9. This is ensured by a thread guide 23 arranged in the area of the clamping roller 16.
- this thread guide 23 so as to be adjustable transversely to the direction of travel 20 of the fiber ribbons 9, so that it is also possible for the filament 19 to be congruent or immediately adjacent to one the fiber ribbon 9 lead to the nip.
- the associated suction slot 21 is also arranged obliquely to the running direction 20 of the fiber ribbon 9.
- the design of the conveyor belt 12 also has a significant part in the invention. It advantageously consists of fabric or fabric which absorbs glass and which is coated differently on both sides. On the side facing the suction element 10, the coating has a sliding-friendly surface, while the coating on the other side is designed to be non-slip in the interest of good and slip-free transport of the fiber ribbon 9. Together with the coatings, the conveyor belt 12 reaches a thickness between 0.9 and 1.2 mm.
- the circumferential air-permeable zone 24 of the conveyor belt 12 is only insignificantly wider than the effective width of the suction slot 21 in the direction of movement 20, taking into account a lateral movement tolerance.
- the conveyor belt 12 is provided with a perforation, which is advantageous in a manner known per se uniformly arranged, circular openings 25.
- the degree of perforation of zone 24, ie the area share of the openings 25 in the total area of zone 24 is between 15 and 30%.
- a common conveyor belt 12 is used for the two suction slots 21 of the suction element 10, which has two air-permeable zones 24 in the sense described above.
