Definitions

  • the present invention relates to a method for knitting a tubular shaped fabric using a flatbed knitting machine, and in particular, to a method for knitting a tubular shaped fabric associated with a change of an all needle arrangement in which all knitting needles within a knitting width are used without any empty needle to a half gauge arrangement in which empty needles are provided between adjoining knitting needles suspending stitches within the knitting width, and to a tubular shaped fabric knitted by the method.
  • a base fabric of a glove 1 as shown in Fig. 7 has been able to be basically knitted as a plain knitting structure in an all needle arrangement in which knitting needles within the knitting width are used with no empty needle.
  • the plain knitting structure is knitted with only front stitches using knitting needles of front and rear needle beds opposing each other in a needle bed gap, to which a knitting yarn is supplied on a flatbed knitting machine.
  • Joining the plain knitting structure fabrics, each of which is knitted on each needle bed, at both ends of the knitting width can produce a tubular shaped fabric.
  • a method for inserting an elastic yarn or the like as a sub yarn into a plain-knitted fabric is known (for example, see Patent Citation 1).
  • the wrist portion 2 is desirably knitted by changing the knit fabric itself from the plain knitting structure to a stretch rib knitting structure.
  • the rib knitting structure must be knitted with front stitch and back stitch alternately, the needles of both needle beds opposing each other in a needle bed gap are used.
  • the rib knitting structure fabric which has front stitches knitted by knitting needles of one needle bed, has back stitches knitted by knitting needles of the other needle bed.
  • the fabric of the rib knitting structure in which the front stitches are knitted by the knitting needles of the other needle bed must be saved by transferring the front stitches knitted by knitting needles of the one needle bed to empty needles of the other needle bed.
  • the arrangement of knitting needles used for knitting on each needle bed must be changed from the all needle arrangement to the half gauge arrangement in which empty needles are provided.
  • a composite needle equipped with a slider to open and close a hook and capable of holding a stitch on a tongue at a head end of the slider may be used.
  • changing from the all needle arrangement to the half gauge arrangement while increasing the knitting width and generating empty needles between adjoining knitting needles is enabled by using hold and place to a tongue and further using a transfer jack (for example, see Patent Citation 2).
  • a transfer jack for example, see Patent Citation 2
  • Patent Citation 2 a procedure to partially obtain the half gauge arrangement at a sweater neckline portion is disclosed.
  • change from the all needle arrangement to the half gauge arrangement is able to be achieved via transfer jack only without utilizing the hold and place to the tongue, too.

  • Prior art document EP 1 550 752 A1 discloses a method comprising the step of forming a tubular knitted fabric via a full-gauge loop arrangement, the knitting width widening step of shifting loops of wale where a laminating part is formed and loops of wale positioned closer to a side end of the knitted fabric than the wale where the laminating part is formed, to provide a half-gauge loop arrangement wherein empty needles for stitch transfer are arranged between needles used for forming the loops of the wale where the laminating part is formed, and the step of knitting the first knitted fabric and the second knitted fabric, while the loops of wale where the laminating part is formed are formed to be fine in size so that when the knitting is ended, the loops of wale where the laminating part is formed can be substantially equal in size to the loops in other region than the loops of wale where the laminating part is formed.
  • Document WO 2007/029695 A1 discloses a method of knitting a knit wear capable of increasing the opening angle of a collar at the V-neck of the knit wear without producing wrinkles.
  • the knit wear having the collar is knitted by using a weft knitting machine. While stitches forming a neck line portion are locked to needles on needle beds in a non-acting state, the body portion of the knit wear is knitted to join the shoulder portions thereof.
  • the stitches of the collar portion of the front body portion of the knit wear locked to the needle bed are transferred so as to be brought into a needle extracted state in which the needles are set idle at least by an increased number of stitches, and the stitches of the collar portion on the rear body portion of the knit wear are transferred so as to be brought into a needle extracted state in which the needles are at least partly set idle so that the lateral knitting length of the knitted fabric locked the needles on the front needle bed can be approximately equal to the lateral knitting length of the knitted fabric locked to the needles on the rear needle bed.
  • Change from the all needle arrangement to the half gauge arrangement shown in Patent Citation 2 is achieved by, first, transferring the stitches temporarily suspended from the knitting needles of one needle bed where empty needles are to be generated, to the transfer jack bed or the like.
  • the stitches are transferred to the transfer jack bed and are returned stitch by stitch while the transfer jack bed is shifted stitch by stitch, whereby the knitting width is widened and an empty needle can be generated between adjoining knitting needles.
  • the knitting width is widened, no new stitch loop is knitted.
  • the knitting yarn is elongated and contracted.
  • a fabric of the plain knitting structure can be knitted even in the half gauge arrangement, and therefore, knitting the base fabric of the glove 1 in the half gauge arrangement can secure empty needles for knitting the wrist portion 2 with the half gauge structure or the like.
  • the base fabric only a fabric could be knitted with so coarse hand value that corresponds to a gauge about one half of the gauge corresponding to the arrangement pitch of the knitting needles.
  • a yarn feeding port is assigned to each fabric suspended from needles of each needle bed, respectively, when the all needle arrangement is changed to the half gauge arrangement in which empty needles are generated between knitting needles in the knitting width.
  • stitches are formed in part and the yarn feeding port is kept in the vicinity of the formed stitches.
  • All stitches within a range from the formed stitch or the adjacent stitch thereof to an end stitch of one side of the knitting width are transferred from knitting needles which suspend the stitches to adjacent knitting needles on the one end side, by moving back and forth in the needle bed gap under a state without causing any effect on stitches suspended from hooks of knitting needles of the opposing needle bed, so that it is possible to generate empty needles adjacent to the formed stitches.
  • the knitting yarn elongates and contracts not only within a range of a limited yarn length existing as already knitted stitches but also including knitting yarn supplied from the yarn feeding port kept in the vicinity of the formed stitches, and therefore, likelihood of yarn break is reduced.
  • Transfer of stitches would be conducted so as not to cause any effect on stitches suspended from hooks of knitting needles of opposing needle bed by use of holding stitches to tongues of compound needles, by the use of transfer jack bed, or the like. Accordingly, knitting can be smoothly changed from the all needle arrangement to the half gauge arrangement without yarn breakage or changes in hand value.
  • the change from the all needle arrangement to the half gauge arrangement is conducted in a single knitting course, so that it is possible to change knitting from plain knitting structure to rib knitting structure without scarcely causing effect on external appearance of knitted fabric.
  • the change from the all needle arrangement to the half gauge arrangement is conducted in a plurality of knitting courses, so that it is possible to, for example, restrict the number of stitch transfers or change the knitting width.
  • the upper limit of the number of the stitch transfers would be fixed in a range in which there is no likelihood of yarn break, and knitting courses are added when the number of transfers exceeds the upper limit, the change from the all needle arrangement to the half gauge arrangement might be conducted with no likelihood of any yarn break.
  • the direction to transfer a stitch to other knitting needle and generate an empty needle between knitting needles is evenly changed over between the one direction and the other direction of the needle row direction of knitting needles. Since the knitting width is widened bringing a balance on both sides of the formed knitted loop, it is possible to widen the knitting width with reducing the number of transferring stitches and without biasing direction of stitches.
  • stitches formed in part are knitted stitch by stitch, and every time one stitch is formed, the stitch is transferred to the other knitting needle to generate an empty knitting needle, and then the knitting width can be widened.
  • the knitting yarn required for generating empty needles is fed from the yarn feeding port kept in the vicinity of the formed stitches, so that empty needles can be generated stably.

    dans lequel le tricotage sur les deux fontures est changé pour passer d'un agencement à toutes les aiguilles, dans lequel aucune aiguille vide n'est présente entre les aiguilles à tricoter tenant des mailles sur la largeur de tricotage, à un agencement à demi-jauge dans lequel une aiguille vide est générée entre des aiguilles à tricoter tenant des mailles sur la largeur de tricotage ; caractérisé en ce que
    lors d'un changement du tricotage passant d'un agencement à toutes les aiguilles à un agencement à demi-jauge, on affecte à chaque fonture (B, F) et à chaque moitié de tissu suspendue aux aiguilles de chaque fonture un port d'alimentation en fil (15, 16) ; et
    on commence sur un côté de la largeur de tricotage avec une répétition pour former une ou plusieurs mailles sur des aiguilles opposées (d, e, D, E) dans chaque fonture, maintenant ainsi les ports d'alimentation en fil (15, 16) au voisinage des mailles nouvellement formées lors d'un déplacement de toutes les mailles dans une plage commençant à l'une des mailles nouvellement formées ou à une maille adjacente et en direction d'une extrémité de la largeur de tricotage, dans un mouvement alternatif sur l'intervalle entre fontures, sans provoquer d'effet sur les mailles suspendues à des aiguilles à tricoter sur la fonture opposée, de façon à déplacer chaque maille d'une aiguille vers une aiguille adjacente, générant ainsi une aiguille vide adjacente à l'une des mailles nouvellement formées, tout en décalant la position où lesdites une ou plusieurs nouvelles mailles sont formées ;
    générant ainsi des aiguilles vides entre chacune des mailles suspendues à des aiguilles à tricoter.
  2. Procédé pour tricoter un tissu tricoté tubulaire (10) selon la revendication 1, dans lequel le changement passant de l'agencement à toutes les aiguilles à l'agencement à demi-jauge est réalisé dans une seule course de tricotage.
  3. Procédé pour tricoter un tissu tricoté tubulaire (10) selon la revendication 1, dans lequel le changement passant de l'agencement à toutes les aiguilles à l'agencement à demi-jauge est réalisé dans une pluralité de courses de tricotage.
