  • the second half of T7 and the first half of T8 correspond to the step D' in the present invention.
  • the stitches C, P1, P2 of the FB are transferred to the opposing BB, and then the BB is racked in the left direction in the plane of drawing and the stitches P1, P2 are returned to the FB in T10, and the stitch C is overlapped on the stitch P1 in T11.
  • the pickup stitch R is also formed on the empty needle of the BB while moving the yarn feeder to the side of the first knitted fabric 100 in the left direction in the plane of drawing.
  • the new stitch P3 following the double stitches C/P1 is formed while moving the yarn feeder to the side of the second knitted fabric 200 in the right direction in the plane of drawing, and thereafter, the yarn feeder is inverted and kept at the side of the first knitted fabric 100.
  • the arrangement state of the stitch and the yarn feeder of T12 a state similar to the state in which the stitches at the boundary of the knitted fabrics 100, 200 is reduced by one stitch from the state of T6 is obtained. Therefore, the first knitted fabric 100 and the second knitted fabric 200 are to be subsequently joined through steps similar to T7 to T12.
  • the first knitted fabric 100 and the second knitted fabric 200 can be joined by the bind-off processing portion as if the loop diagram of the first embodiment reverencing Fig. 5 is seen from the back side. Therefore, the knitted fabric of the second embodiment is a knitted fabric in which the knitted fabrics 100, 200 are joined by the bind-off processing portion excelling in stretchability, similar to the knitted fabric of the first embodiment.
  • the bind-off processing portion in the second embodiment the bind-off stitches are lined on the front side of the knitted fabric, and hence such bind-off stitches can be used as a design of the knitted fabric.
  • the present invention is not limited to the embodiments described above, and can be appropriately modified within a scope not deviating from the scope of the claims.
  • the formation of the bind-off processing portion 5 may be a combination of the elastic yarn and the normal knitting yarn aligned.

Claims (6)

  1. Procédé de jonction pour un tissu tricoté consistant à connecter par l'intermédiaire d'un procédé de rabat un premier tissu tricoté (100) et un deuxième tissu tricoté (200), qui sont tricotés indépendamment et alignés dans une direction de largeur de tricotage, avec des extrémités dans une direction de colonne de mailles des tissus tricotés (100, 200) qui butent l'une contre l'autre, en utilisant une machine à tricoter à plat comportant au moins une fonture avant et une fonture arrière et dans laquelle au moins l'une de la fonture avant ou de la fonture arrière peut être déplacée dans une direction transversale et des mailles peuvent être transférées entre les fontures avant et arrière, le procédé étant caractérisé par un processus consistant à répéter en alternance
    lorsqu'on commence à joindre les tissus tricotés (100, 200) à partir d'une frontière du premier tissu tricoté (100) et du deuxième tissu tricoté (200),
    faire chevaucher deux mailles (β, γ (A, B)) alignées au niveau de l'extrémité du côté de la frontière dans le premier tissu tricoté (100) afin qu'une maille sur le côté de la frontière devienne une première maille de rabat formée dans le premier tissu tricoté (100) et former une nouvelle maille (P1) destinée à devenir une première maille de rabat suivante à la suite des doubles mailles ((β/γ) (B/A)) ; et
    faire chevaucher deux mailles (P0, B (α, β)) alignées au niveau de l'extrémité du côté de frontière dans le deuxième tissu tricoté (200) afin qu'une maille sur le côté de la frontière devienne une deuxième maille de rabat formée dans le deuxième tissu tricoté (200) et former une nouvelle maille (P2) destinée à devenir une deuxième maille de rabat suivante à la suite des doubles mailles (P0/B (β/α)) ;
    utiliser un même fil à tricoter, dans lequel
    la longueur de fil connectant la première maille de rabat (P1) et la deuxième maille de rabat (P2) est augmentée en formant une maille de relevée (R) sur une aiguille vide de la première fonture ou de la deuxième fonture entre la formation de la première maille de rabat et la formation de la deuxième maille de rabat dans le processus répétitif et retirer la maille de relevée (R) de la fonture.
  2. Procédé de jonction pour un tissu tricoté selon la revendication 1, dans lequel on utilise un fil élastique pour joindre le premier tissu tricoté (100) et le deuxième tissu tricoté (200).
  3. Procédé de jonction pour un tissu tricoté selon la revendication 1 ou 2, dans lequel la première maille de rabat (P1) et la deuxième maille de rabat (P2) sont formées en tant que mailles arrière dans le processus répétitif ; et
    un fil à tricoter s'étendant à partir de la maille de rabat (P1 (P2)) formée en premier jusqu'à un distributeur de fil est croisé sur le côté avant de la maille de rabat (P1 (P2)) formée en premier pour former une maille de rabat suivante (P2 (P1)) en déplaçant le distributeur de fil après la formation de la première maille de rabat (P1) ou de la deuxième maille de rabat (P2) et avant de former la maille de rabat suivante (P2 (P1)).
  4. Procédé de jonction pour un tissu tricoté selon la revendication 3, dans lequel le processus répétitif comprend :
