Description

  The present invention relates to a knitting method of a knitted fabric for knitting a new knitted fabric following an existing knitted fabric that is knitted using a flat knitting machine and locked to a needle bed of the flat knitting machine.

  Conventionally, as a method of knitting a knitted fabric using a flat knitting machine having at least a pair of front and back needle beds, for example, knitting yarns from two yarn feeders as described in Patent Document 1 are entangled between front and back needle beds. A method for knitting the set-up portion of the knitted fabric is also disclosed. In addition to the technique disclosed in Patent Document 1, a new knitted fabric is knitted following an existing knitted fabric already knitted on the needle bed of a flat knitting machine. For example, firstly, a knitted fabric (prefabricated knitted fabric) is knitted, and a new knitted fabric is knitted through a yarn formed following the stitch of the final course of the discarded knitted fabric. In addition, there is a case where one heel (prefabricated knitted fabric) is knitted and a new heel is formed on the heel through a thread. In such a case, a new knitted fabric can be knitted while applying an appropriate tension by pulling the ready-made knitted fabric below the needle bed with a lowering roller, and the appearance of the new knitted fabric is improved. Can do. The ready-made knitted fabric and the new knitted fabric can be separated by pulling out the yarn after the knitting of the new knitted fabric is completed.

  FIG. 3 is a knitting process diagram relating to a knitting fabric setting method for setting up a new knitted fabric following an existing knitted fabric. The left column in the figure shows the number of the knitting step, and the right column shows the actual knitting yarn locking state in the needle bed. The circles in the right column are stitches, the V-shaped are stitches, and the portions where knitting operations are actually performed in the columns are indicated by bold lines. The numbers at the top of the figure indicate the positions of the knitting needles on the front needle bed (hereinafter referred to as FB) and the rear needle bed (hereinafter referred to as BB). Note that the manner of viewing the described drawings is the same as in FIGS.

  In S1, the locked state of the take-off yarn 20 composed of a stitch knitted using a knitting yarn different from that of the ready-made knitted fabric with respect to the final course of the ready-made knitted fabric is shown. From this state, in S2, the knitting yarn is supplied in a zigzag manner to the FB knitting needle and the BB knitting needle to form the set-up portion 30 which is the first part of the knitted fabric. Here, since the stitches of the pulling yarn 20 are formed on the BB knitting needles 1, 3, 5, 7, and 9 at the stage of S1, they are formed on the BB knitting needles 1, 3, 5, 7, and 9 at S2. The stitches of the set-up portion 30 are stitches that continue in the wale direction of the stitches of the punching yarn 20. Then, in order to knit the knitted fabric following the set-up unit 30, front bag knitting is performed on a plurality of hooks of the set-up unit 30 in S3, and rear bag knitting is performed on a plurality of stitches of the set-up unit 30 in S4. These front bag knitting and rear bag knitting are knitting performed in order to prevent the set-up portion 30 from unraveling.

International Publication No. 2009/084167

  In the conventional knitting fabric set-up method described with reference to FIG. 3 above, among the stitches that are the set-up portion of the knitted fabric, the knitting needles 1, 3, 5, 7, and 9 of S2 are locked. Since the stitches are formed following the wale direction of the stitches of the drawn yarn that is pulled down below the mouth, these stitches are also strongly pulled down below the mouth. As a result, the set-up portion is stretched and easily loosened, and the appearance of the knitted fabric may be impaired.

  The present invention has been made in view of the above circumstances, and one of its purposes is to prevent the set-up portion of the knitted fabric from being stretched and loosened when knitting the set-up portion of the knitted fabric. An object of the present invention is to provide a method for setting up a knitted fabric that can be performed.

The knitting method of the knitted fabric of the present invention includes at least a pair of front and back needle beds, and uses a flat knitting machine capable of transferring stitches between the front and rear needle beds, and is locked to the needle bed of the flat knitting machine. A method for setting up a knitted fabric for setting up a new knitted fabric following an established knitted fabric, comprising the following steps.
(Step A) Knitting the stitches of the drawn yarn following the wale direction of the final course of the ready-made knitted fabric.
(Step B) A set-up portion of the knitted fabric is knitted by forming hooks on a plurality of empty needles where the stitches of the drawn yarn are not locked.
(Step C) The stitches of the drawn yarn and the hooks of the set-up portion are overlapped.
(Process D) The stitch row following the wale direction of the set-up portion is knitted by the front bag knitting and the rear bag knitting.

  As one form of the set-up method of the knitted fabric of the present invention, in step C, the stitches of the drawn yarn may be transferred so that the stitches are overlapped with the hooks of the set-up portion.

  Further, as one form of the set-up method of the knitted fabric of the present invention, in Step B, the stitches of the set-up portion are formed only at one of the front and back needle beds, and in Step C, the stitches of the set-up portion are transferred. Thus, the stitches may be overlapped with the stitches of the thread.

  According to the knitting fabric set-up method of the present invention, when the knitted fabric set-up portion is formed, the set-up portion is not stretched and loosened. This is because the set-up portion of the knitted fabric is knitted in step B of the set-up method of the knitted fabric of the present invention without being continuous with the drawn yarn that is tensioned downward toward the lower portion of the mouth. This is because the tension toward the lower portion of the mouth does not act on the set-up portion until completion. Moreover, since the set-up portion and the drawn yarn are overlapped after the set-up portion is completed, when the knitted fabric following the set-up portion is knitted, the lip of the knitted fabric that follows the set-up portion and the set-up portion is used. The knitted fabric can be knitted while applying appropriate tension downward.

  According to the knitting method of the knitted fabric of the present invention in which the stitches of the drawn yarn are transferred in the step C, the stitches of the drawn yarn and the hooks of the set-up portion can be reliably overlapped. This is because it is easier to transfer stitches than to transfer stitches.

  According to the knitting method of the knitted fabric of the present invention in which the stitches of the set-up portion are formed only at either the front or back needle bed in the process B, the set-up portion in a very clogged state can be knitted. This is because the knitting yarn of the set-up portion does not cross between the front and back needle beds, so that the yarn length between the hooks of the set-up portion does not become too long.

It is a figure which shows the knitting process which concerns on the set-up method of the knitted fabric of Embodiment 1. FIG. It is a figure which shows the knitting process which concerns on the set-up method of the knitted fabric of Embodiment 2. FIG. It is a figure which shows the knitting process which concerns on the setting-up method of the conventional knitted fabric.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Each knitting described in the embodiment will be described with reference to a knitting example using a two-bed flat knitting machine that includes at least a pair of front and back needle beds and can transfer between the front and back needle beds. Of course, the flat knitting machine to be used may be a two-bed flat knitting machine equipped with a transfer jack bed or a four-bed flat knitting machine.

<Embodiment 1>
In the present embodiment, the knitted fabric (prefabricated knitted fabric) is knitted with FB, the stitches are formed with the knitting yarns as the take-off yarns on the final course of the discarded knitted fabrics, and then the knitted fabrics are formed following the stitches of the take-off yarns. An example to which the set-up method of the present invention is applied in setting up will be described with reference to FIG.

  In T1 of FIG. 1, the knitting needles 1, 3, 5, 7, and 9 of the FB are in a state in which the stitches of the drawn yarn 20 formed following the final course of the discarded knitted fabric are locked. From this state, at T2, stitches are formed in a zigzag manner on the FB and BB empty needles where the stitches of the punched yarn 20 are avoided. At T2, the stitches formed on the knitting needles 1, 3, 5, 7, 9 of the BB and the knitting needles 2, 4, 6, 8, 10 of the FB are the set-up portions 30 of the knitted fabric. The reason for assigning the hooks to FB and BB is to perform front bag knitting and rear bag knitting at T4 and T5 described later.

  Since the set-up portion 30 knitted at T2 is knitted independently without being continuous with the drawn yarn 20, the strong pull-down force by the drawn yarn 20 in the downward direction of the mouth is knitted when the set-up portion 30 is knitted. Does not act on the knitting yarn. As a result, the space between the stitches of the set-up portion 30 is stretched and does not loosen, and becomes clogged.

  Next, at T3, the stitches of the take-off thread 20 locked to the FB knitting needles 1, 3, 5, 7, and 9 at T1 are transferred to the opposing BB knitting needles 1, 3, 5, 7, and 9. To do. Thereby, the stitches of the punching yarn 20 and the hooks of the set-up portion 30 are overlapped.

  Finally, as shown in T4 and T5, front bag knitting and rear bag knitting are performed, and a new stitch is formed following the hook of the set-up portion 30 locked to the knitting needles 2, 4, 6, 8, 10 of the FB. , Knitting needles 1, 3, 5, 7, and 9 are formed to form a new stitch following the double stitches, so that the discarded knitted fabric and the set-up portion 30 are connected to each other through the thread 20. . At this time, the stitches of the take-out yarn 20 on which a pulling force toward the lower side of the tooth mouth acts and the hooks of a part of the set-up portion 30 are overlapped, so that the stitch row knitted by the front bag knitting and the rear bag knitting. A pulling force toward the lower part of the mouth of the mouth acts on. As a result, the knitted fabric following the set-up portion 30 can be knitted while applying an appropriate tension.

  According to the knitting process of the first embodiment described above, the set-up portion 30 of the knitted fabric is not stretched and loosened. This is because, in T2, the set-up portion 30 is knitted independently of the drawn yarn that is tensioned downward in the tooth opening, so that excessive pulling down of the knitting yarn in the set-up portion 30 toward the lower tooth opening is performed. This is because the force does not work. Since the set-up portion 30 formed without looseness is in a more tight state than the conventional set-up portion, it has an excellent appearance. Further, since the entanglement of the drawn yarn 20 with respect to the set-up portion 30 is loose as compared with the conventional set-up method, the drawn yarn 20 can be easily removed.

<Embodiment 2>
In the present embodiment, unlike the above-described first embodiment, a method for setting up the knitted fabric of the present invention in which the stitches of the set-up portion are overlapped with the stitches of the cut yarn will be described with reference to FIG.

  U1 in FIG. 2 shows a state in which the stitches of the drawn yarn 20 formed following the final course of the discarded knitted fabric are locked to the knitting needles 1, 3, 5, 7, 9 of the BB. From this state, in U2, the stitches of the set-up portion 30 are formed on the knitting needles 1 to 10 of the FB, avoiding the BB where the stitches of the drawn yarn 20 are locked. Since the set-up portion 30 formed by this U2 is knitted independently of the cut yarn 20, the space between the hooks of the set-up portion 30 is not stretched by the cut yarn 20, and is jammed. It becomes a state. Further, by knitting the set-up portion 30 only on the FB side, the knitting yarn of the set-up portion 30 does not cross between FB and BB, and the yarn length between each hook of the set-up portion 30 is reduced. Shorter and more tightly packed between each hook.

  Next, in U3, the hooks of the set-up portion 30 formed on the FB knitting needles 1, 3, 5, 7, and 9 in U2 are transferred to the opposing BB knitting needles 1, 3, 5, 7, and 9. The hooks of the set-up unit 30 are allocated to FB and BB. By this U3, the stitches of the yarn 20 and the hooks of the set-up portion 30 are overlapped. Thereafter, as shown in U4 and U5, the front bag knitting and the rear bag knitting are performed, and a new stitch is formed following the hook of the set-up portion 30 locked to the knitting needles 2, 4, 6, 8, 10 of the FB. A new stitch is formed following the double stitches locked to the knitting needles 1, 3, 5, 7, and 9 of the BB, and the portion following the set-up portion 30 in the knitted fabric is knitted, so that the discarded knitted fabric and the knitted fabric are knitted. The take-out part 30 is connected via the thread 20.

  Even in the knitted fabric knitted by the knitting process of the second embodiment described above, the appearance of the set-up portion of the knitted fabric is superior to the conventional knitted fabric knitted by the knitting process of the first embodiment.

  The embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist of the present invention. Whatever the change is made, the stitches of the set-up portion may be formed while avoiding the stitches of the drawn yarn. For example, in the first embodiment, the knitting needle that forms the stitch of the take-off yarn 20 does not have to be a knitting needle in a position facing the knitting needle to which the hook of the set-up portion 30 is locked. Specifically, at T1 of the first embodiment, the stitches of the punched yarn 20 may be locked to the knitting needles 2, 4, 6, 8, 10 of the BB. In that case, after T2 is transferred to the knitting needles 1, 3, 5, 7, and 9 of the FB, T3 may be performed. In addition, when forming the stitches of the set-up portion 30, it is not necessary to form stitches alternately on the FB and BB one by one. For example, it is possible to repeat the formation of two hooks on FB and the formation of one hook on BB, or vice versa, or the formation of two hooks on FB and BB. good.
