Definitions

  • This invention relates to a method of recycling selvage warp yarns in a fabric weaving operation and an apparatus for carrying out the method.
  • the selvage warp yarns that bind the fill yarns during the weaving operation were slit from the fabric warp yarns and discarded.
  • DE 3025744 discloses an apparatus wherein the selvage warp yarns are spaced from the main warp yarns forming the fabric.
  • the continuous selvage warp yarns are spliced from the main fabric body after weaving, the cut warp yarns are removed, and the selvage warp yarns are returned to the weaving machine.
  • This invention is also directed to a method and apparatus for reducing waste by recycling the warp yarns of the selvage.
  • the selvage warp yarns are guided in a continuous pattern through the loom, returned through a spreader means to discard the cut fill fringe yarns and recombined to go through the loom again.
  • a method of recycling selvage warp yarns in a weaving operation comprised of:
  • an apparatus for recycling the selvage warp yarns in a weaving operation comprising:
  • a fabric weaving system is shown generally at 10 where the main fabric warp yarns 12 are fed from creels 13 (FIGURE 2) along with the continuous selvage warp yarns 14 to the compression stand 16 into the loom 18 through guide rollers 20 under a dancer roll 22 which reciprocates vertically as shown by the double headed arrow to adjust the tension on the warp yarns.
  • the warp yarns next pass through drop wires 24 which detect if any of the warp yarns are broken to halt the weaving operation. Then the warp yarns pass through the heddles 26 which raise and lower adjacent warp yarns or groups thereof to form the shed 25 wherethrough the fill yarns 27 are passed to form the weave.
  • the reed 28 is a comb-like device that separates the warp yarns and also beats each succeeding fill yarn against that already woven.
  • the thus woven fabric then passes past the slitter means 30 which slits the fill yarns 27 between the innermost continuous selvage yarn 14 and the outermost main fabric warn yarn 12. It is preferred that in weaving, a space of from 3 to 9 mm be left between the aforementioned yarns.
  • the selvage is then separated over guide roller 33 from the main fabric where the main fabric is wound on wind-up roll 32 and the selvage is guided on roll 34 beneath the loom through horn guide 36 and onto spreader bar 41 which has spaced guides 42 which separate the continuous selvage warp yarns 14 to allow the fill fringe yarns 40 to be discharged from the continuous selvage warp yarns 14 with the help of shaker bar 38 which is attached to the dancer roll 22 with its up and down motion.
  • the continuous selvage warp yarns are then converged over rollers 44 to pass through the loom again.

  1. Procédé de recyclage de fils de chaíne de lisière dans une opération de tissage d'un tissu, comprenant le fait de :
    a. procurer plusieurs fils de chaíne de lisière (14) qui forment une boucle continue à travers le métier à tisser (18) ;
    b. alimenter ensuite les fils de chaíne de lisière (14) à un fil de chaíne de tissu externe (12) ;
    c. tisser des duites (27) à travers tous les fils de chaíne (12, 14) ;
    d. découper les duites (27) pour obtenir le fil de chaíne de tissu externe (12) et le fil de chaíne de lisière interne (14) ;
    e. faire passer les fils de chaíne de lisière (14) à travers un séparateur (41) pour permettre aux extrémités de franges (40) des duites découpées de s'écarter des fils de chaíne de lisière (14) ;
    f. repeigner les fils de chaíne de lisière (14) à des fins de nouvelle alimentation à travers le métier à tisser (18) ;
       dans lequel le procédé est caractérisé par le fait de :
    après avoir découpé les fils de duites (27) pour obtenir le fil de chaíne de tissu externe (12) et le fil de chaíne de lisière interne (14), faire passer les extrémités de franges (40) des fils de duites découpés et les fils de chaíne de lisière (14) à travers une barre secoueuse (38) afin de secouer les fils de franges (40) des duites découpées par rapport aux fils de chaíne de lisière continus (14).
  2. Procédé selon la revendication 1, dans lequel le fil de chaíne de tissu le plus externe (14) est espacé du fil de chaíne de lisière continu le plus interne (12) sur distance de 3 à 9 mm.
  3. Appareil pour le recyclage de fils de chaíne de lisière (14) dans une opération de tissage d'un tissu, comprenant :
    a. un moyen (44) pour guider plusieurs fils de chaíne de lisière continus (14) dans un métier à tisser (18) ;
    b, un métier à tisser (18) pour tisser les fils de chaíne (14) avec des duites (27) afin d'obtenir un tissu ;
    c. un moyen de découpe (30) pour découper les duites (27) pour obtenir un fil de chaíne de lisière interne (14) et un fil de chaíne de tissu externe (12) ;
    l'appareil étant caractérisé par :
    d. des galets de guidage (33, 34) pour diriger la portion de lisière découpée à travers un guide en forme de cornet (36) ;
    e. une barre secoueuse (38) destinée à secouer les fils de franges (40) des duites découpées par rapport aux fils de chaíne de lisière continus (14) ;
    f. une barre répandeuse (41) possédant des guides espacés (42) pour chaque fil de chaíne de lisière continu (14) afin de favoriser l'écartement des fils de frange de duite (40).
