<Embodiment 1>

"shoe"

Fig. 1 shows a shoe (shoe upper) 1 in a woman's shallow-mouth, buckleless shoe-less shape. The shoe 1 is provided with a base fabric portion 2 having a shoe opening 5 and formed into a shoe shape, and an additional fabric portion 3 (refer to a hatched portion) that covers the toe portion of the base fabric portion 2. The base fabric portion 2 is composed of a sole cover portion 20 covering the sole of the wearer's foot and an instep cover portion 21 covering a portion of the back side of the wearer's foot. Although in Figure 1 Although not observed, the base fabric portion 2 having the same shape as the additional fabric portion 3 is present inside the additional fabric portion 3. By attaching a sole with a heel to the bottom of the shoe 1, a pair of women's shallow-mouth buckleless shoes can be made.

The base fabric portion 2 and the additional fabric portion 3 are integrally knitted in a seamless manner using a flat knitting machine. The additional fabric portion 3 is joined to one of the toe sides of the edge portion of the shoe opening 5 formed in the base fabric portion 2 by knitting. Here, in Fig. 1, the position which becomes the point of knitting is indicated by the black solid arrow. The uppercase letters attached to the black solid arrows correspond to the letters of Figs. 2 and 3 referred to in the description of the method of knitting the shoes described below.

The knitting yarn of the woven base fabric portion 2 and the additional woven fabric portion 3 is not particularly limited. In this example, the two yarns 2 and 3 are knitted using a knitting yarn containing a hot melt yarn. In the case of a knitting yarn containing a hot melt yarn, the shoe 1 can be formed into a desired shape by heat-sealing the shoe 1 into a wooden tweezers.

The base fabric portion 2 and the additional fabric portion 3 are fixed so as not to be offset from each other. The two, two, and 3 may be fixed by the hot melt yarn, or may be fixed by the adhesive, or may be fixed by sewing. Of course, it is also possible to use both of them in combination with sewing to fix the two, two, and three.

"Weaving method of shoes"

An example of the knitting method of the shoe 1 described above will be described based on the schematic diagram of Fig. 2 . In Fig. 2, letters are placed at the position which becomes the main point of knitting of the shoe 1. Further, in Fig. 2, the knitting forward direction (the same direction as the yarn loop) is indicated by a thick arrow. For the flat knitting machine used for weaving, a double needle bed flat knitting machine having a front needle bed and a rear needle bed and capable of transferring the yarn loop between the front and rear needle beds can be used. Of course, the shoe 1 can also be woven using a flat knitting machine other than a double needle bed flat knitting machine such as a four-bed flat knitting machine.

First, as shown in Fig. 2(A), weaving is started from the toe side of the base fabric portion 2, and the base fabric portion 2 is knitted until one portion of the opening portion 5 is formed. The portion of the base fabric portion 2 on the side close to the paper surface corresponds to the right side portion of the base fabric portion 2, and the portion of the base fabric portion 2 on the inner side of the paper surface corresponds to the left side portion of the base fabric portion. The right part is woven by the needle bed before the flat knitting machine, and the left part is woven by the rear needle bed. Therefore, in the end portion of the base fabric portion 2 in the warp direction, the line E-F-H is locked by the front needle bed, and the line E-G-H is locked by the rear needle bed. Preferably, when the base fabric portion 2 is knitted, the knitting width of the base fabric portion 2 is gradually increased from the toe so that the portion of the base fabric portion 2 on the toe side coincides with the shape of the foot.

Further, as shown in Fig. 2(A), a bag-shaped additional fabric portion 3 having one end open and the other end closed is also knitted together with the base fabric portion 2. The additional fabric portion 3 of this example is knitted in a bag shape whose starting end portion is closed. Since the beginning end portion of the additional fabric portion 3 is disposed on the toe side of the shoe 1 shown in Fig. 1, it is preferable that the knitting width of the additional fabric portion 3 is gradually increased from the beginning end portion toward the end portion portion. The line A-B-D which becomes the additional fabric part 3 is locked by the front needle bed, and the line A-C-D is locked by the back needle bed. The knitting of the additional woven fabric portion 3 may be performed before the woven base fabric portion 2, or may be performed while the base fabric portion 2 is woven.

Next, the line B-D-C of the additional fabric portion 3 is subjected to a loop process, and the base fabric portion 2 and the additional fabric portion 3 are gradually joined while increasing the number of weft knittings of the base fabric portion 2 (see FIG. 3 below). As a result, as shown in FIG. 2(B), one of the opening edge portions of the additional woven fabric portion 3 is joined to the toe side edge portion of the edge portion of the shoe upper 5 (see FIG. 1) of the base fabric portion 2. Both end portions X and Y of the joint portion between the base fabric portion 2 and the additional fabric portion 3 correspond to the positions of X and Y shown in Fig. 1 .

The method of joining the base fabric portion 2 and the additional fabric portion 3 is as long as it is used. The joining method of the overlapping stitches is not particularly limited. An example of the joining method will be described using the knitting step diagram of Fig. 3. In the knitting example shown in Fig. 3, the base fabric portion 2 and the additional fabric portion 3 are joined while the number of knitting weaves of the base fabric portion 2 is increased. The "S+ number" in Fig. 3 indicates the number of the knitting step, FB indicates the front needle bed, and BB indicates the rear needle bed.

In S0, the locked state of the yarn loop at the time of Fig. 2(A) is shown. From this state, the loop of the B-D-C of the additional fabric portion 3 indicated by the broken line in S1 is subjected to a loop process. The pressure ring processing is a knitting process known in the art: by repeatedly overlapping adjacent yarn loops, a yarn loop continuous in the direction of the loop of the overlap coil is formed, thereby adding the yarn of the end portion of the fabric portion 3 in the warp direction. The circle is unfastened from the needle bed.

Next, as indicated by the arrows at the ends of S1, the yarn loops of the base fabric portion 2 locked by the FB (BB) and the yarn loops of the additional fabric portion 3 are overlapped with each other (see S2). Here, when the yarn loops of the two portions 2 and 3 are overlapped, the additional fabric portion 3 may be moved to the side of the base fabric portion 2 as indicated by S2, or the base fabric portion 2 may be different from the illustrated example. Moves to the side of the additional fabric portion 3.

As shown by S2, after the overlapping stitches shown by the double circles are formed, as shown by the C-shaped reciprocating arrows, the loops of the loops of the base fabric portion 2 including the overlapping stitches in the warp direction are knitted. The overlapping stitch is fixed by the C-shaped knitting, and one of the base fabric portions 2 is partially joined to one of the additional fabric portions 3. Thereafter, by repeating the movement of the additional woven fabric portion 3 toward the base fabric portion 2, overlapping stitches are formed between FB and BB, and a lap line continuous in the warp direction of the yarn loop of the base fabric portion 2 including the overlapping stitches is knitted. The base fabric portion 2 is joined to the additional fabric portion 3 by joining using overlapping stitches. The joint portion formed by joining the base fabric portion 2 and the additional fabric portion 3 naturally includes an overlapping stitch, and the weight can be confirmed by observing the shoe 1. Stacked coils.

As shown in Fig. 2(B), after the joining of the base fabric portion 2 and the additional fabric portion 3 is completed, as shown in Fig. 2(C), the remaining portion of the base fabric portion 2 is knitted. The remainder of the base fabric portion 2 can be woven by using a C-shaped weave of FB and BB or the like. The base fabric portion 2 conforming to the shape of the foot can be formed by appropriately increasing or decreasing the knitting width of the remaining portion.

"How to make shoes"

After the shoe 1 shown in FIG. 2(C) is obtained by the above-described method of weaving the shoe, the additional fabric portion 3 is folded back in a folded manner to cover the outer side of the toe portion of the base fabric portion 2 at the toe portion. A two-layered state in which the base fabric portion 2 and the additional fabric portion 3 are overlapped is formed. By covering the outer side of the base fabric portion 2 with the additional fabric portion 3, the additional fabric portion 3 can be observed from the outside of the shoe 1, and the additional fabric portion 3 can be one of the designs of the shoe 1. For example, the design of the shoe 1 can be changed by adjusting the size of the additional fabric portion 3 or by making the color of the knitting yarn of the woven additional fabric portion 3 different from the knitting yarn of the base fabric portion 2.

The direction of the loop of the base fabric portion 2 is the same as the direction of the loop of the additional fabric portion 3 covering the base fabric portion 2. This is because the base fabric portion 2 and the additional fabric portion 3 are knitted in accordance with the knitting method of the shoe 1 described with reference to Figs. 2 and 3 .

Here, the additional fabric portion 3 may be folded back toward the inside of the base fabric portion 2, and the additional fabric portion 3 may be disposed inside the toe portion of the base fabric portion 2. In this case, the shoe 1 in which the additional fabric portion 3 is not observed from the outside of the shoe 1 can be obtained, and the shoe 1 having a simple design can be obtained.

Finally, the shoe 1 shown in Fig. 1 is completed by heat-inserting the shoe 1 into a wooden tweezers. At this time, the knitting yarn of the knitted base fabric portion 2 and the hot-melt yarn included in the knitting yarn of the knitted additional fabric portion 3 are melted, and the additional fabric portion 3 is fixed to the base fabric portion 2. the result, The shoe 1 is a double-layered state in which the base fabric portion 2 and the additional fabric portion 3 are superposed. Here, in order to maintain the two-layer state, an adhesive may be applied between the base fabric portion 2 and the additional fabric portion 3, and the heat-treated shoe 1 may be sewn.

"effect"

The shoe 1 described above is partially reinforced by the addition of the fabric portion 3 to its toe portion. The shoe 1 which requires the strength of the toe to be locally reinforced has the advantages of a thin, light and flexible knitted product, and is comfortable to wear on the foot.

<Embodiment 2>

In the first embodiment, the knitting of the shoe 1 is started from the position corresponding to the toe of the shoe 1 (the base fabric portion 2). On the other hand, the knitting of the shoe 1 may be started from the position corresponding to the shoe 1 (the base fabric portion 2) shown in Fig. 1, and the additional fabric portion may be formed at the position of the heel. In this case, the portion of the base fabric portion 2 that follows the side is knitted, and the bag-like additional fabric portion 3 joined to the portion of the heel side is knitted, and the edge portion of the shoe mouth 5 of the base fabric portion 2 is followed by The side edge portion may be joined to one of the opening edge portions of the additional fabric portion 3. The joining method can be carried out in the same manner as in the first embodiment.
