It can also be knitted by folding it back in a C-shape with the needle bed arranged.

≪Knitting procedure≫
For the main body region α, first, a set-up portion is formed on the needle bed, and following the set-up portion, knitting is performed from the toe side toward the buttocks region β by tubular knitting. Subsequently, in order to form the buttock region β, first, as shown in FIG. 3, the stitch in the wale direction on the right side of the paper surface is less than the stitch in the wale direction on the sole side on the left side of the paper surface. A turn-back portion composed of turn-back end portions 10, 20, 11, 21, 12, and 22 and turn-back intermediate portions 13a, 14a, 13b, 14b, 13c, and 14c while being folded back and knitted between both needle beds. Is formed multiple times. Specifically, in the case of the right portion R of the shoe upper 1, the number of stitches in the course direction is increased between bc of the turned-back end portion 10, and the number of stitches in the course direction is increased between cd of the turned-back end portion 10. Decrease and carry out turn back knitting. Then, turn-back knitting is similarly performed on the turn-back end portions 11 and 12. At that time, bc of the turn-back end portion 10 is knitted continuously in the ab bale direction of the main body region α, and the main body region α and the turn-back end portion 10 are joined. In addition, kn of the turn-back end portion 11 is knitted continuously in the cd wale direction of the turn-back end portion 10, and the turn-back end portion 10 and the turn-back end portion 11 are joined. Then, f-g of the turn-back end portion 12 is knitted continuously in the ef wale direction of the turn-back end portion 11, and the turn-back end portion 11 and the turn-back end portion 12 are joined. As a result, gore lines 30, 31, and 32 shown in FIGS. 1 and 2 are formed. Further, the turn back intermediate portions 13a, 13b, and 13c are also knitted toward the wear mouth 5 in the wale direction simultaneously with the formation of the turn back end portions 10, 11, and 12, respectively.

  Since the right portion R and the left portion L of the shoe upper 1 are connected on the sole cover portion 2 side, the turn-back intermediate portions 14a, 14b, 14c and the turn-back end portion 20 which are left portions L that do not appear in FIG. , 21 and 22 and the turn-back portion formed with the gore lines 40, 41 and 42 is knitted in the same procedure as the right portion R at the same time. That is, since the knitting is performed in a C shape between both needle beds, the knitting is performed in the order of 10 → 13a → 14a → 20 → 20 → 14a → 13a → 10, and so on. As a result, a turn-back portion constituted by the turn-back intermediate portions 13a, 13b, 13c, 14a, 14b, 14c and the left and right turn-back end portions 10, 11, 12, 20, 21, 22 is formed. In this way, by forming the turn-back portion a plurality of times, a smooth curved surface can be formed, and the shape enveloping the collar portion 6 can be obtained. That is, by changing the size of the shape of the turn-back end portion, a heel portion that fits the foot can be easily formed.

  Further, the knitting width of the turn-back portion is knitted with the same width as the knitting width of the instep cover portion 3 and the sole cover portion 2. Specifically, the knitting widths of bc, de, and f-g of the turn-back end portions 10, 11, and 12 shown in FIG. 3 and a of the main body region α corresponding to the instep cover portion 3 and the sole cover portion 2 are shown. Knit so that -b has the same knitting width. That is, knitting is performed so that c, e, g of the turn-back end portions 10, 11, 12 and a of the main body region α are aligned on the same straight line. Thereby, the level | step difference of a back side and the wear mouth 5 toe side end can be decreased. Thereby, when knitting by inserting a rubber thread into the wear mouth 5, the expansion / contraction direction approaches a constant value and fits to the wearer's ankle. The knitting width of the turn-back end portions 10, 11, 12 and the knitting width of the main body region α may be knitted even if they are not the same width.

  And the heel cover part 4 which is a part which covers a wearer's Achilles tendon shown in FIG. 3 arrange | positions the right side part R of the shoe upper 1 to the front needle bed of a flat knitting machine, and the left side part L to a back needle bed, In the case of the present embodiment knitting from the side toward the wearer 5, the stitch group 4a composed of a plurality of stitches at the center of the two turnback intermediate portions 13c, 14c is turned from the center of the turnback intermediate portion 13c. The inner knitting and the knit knitting, which reduce the stitches by moving in the away direction, are turned back and performed between ij of the intermediate portion 13c. Further, when knitting from the wear mouth 5 side toward the toe side, the stitch group 4a composed of a plurality of stitches at the center of the turnback intermediate portion 13c is moved in the turnback intermediate portion 13c toward the center of the turnback intermediate portion 13c. Thus, the increase knitting and the knit knitting, in which the stitches are increased, are turned back and performed between ij of the intermediate portion 13c.

  Further, when both the left portion L and the right portion R of the shoe upper 1 are arranged on the front and rear needle beds and knitted from the toe side toward the wearing mouth 5, the turn-back end portions 12 and 22 and the turn-back intermediate portions 13c and 14c are provided. Knitting and knit knitting are alternately performed to reduce the stitches by moving in the center direction. Further, when knitting from the wear mouth 5 side toward the toe side, the inner knitting and knit increase the stitches by moving the turn-back end portions 12, 22 and the turn-back intermediate portions 13c, 14c away from the center. The knitting is performed alternately, and the stitches are reduced or increased. Since the same knitting is performed in the left portion L of the shoe upper 1 (not shown in FIG. 3), the turn-back end portion 22, the turn-back intermediate portion 14c, and the stitch group 4b shown in FIG. The It should be noted that the above-described reduced knitting and increased knitted knitting can be performed as reduced knitting and increased outer knitting.

  When the knitting of the turn-back portion composed of the turn-back end portions 10, 20, 11, 21, 12, 22 and the turn-back intermediate portions 13a, 14a, 13b, 14b, 13c, 14c is completed, the symbols a, c, e, “g” is connected to one, and the turn-back portions are arranged in a circumferential shape around the connected portion. In the left portion L of the shoe upper 1 (not shown in FIG. 3), the same knitting is performed simultaneously with the right portion R. As a result, the collar portion 6 is formed by the turn-back portion constituted by the turn-back end portions 10, 20, 11, 21, 12, 22 and the turn-back intermediate portions 13a, 14a, 13b, 14b, 13c, 14c and the heel cover portion 4. The Further, after forming the turn-back end portions 10, 11, 12, 20, 21, and 22, the shoe mouth 5 is knitted in a circular shape, and the g-h of the turn-back end portion 12 and the shoe mouth 5 are connected to each other so that the shoe upper The formation of 1 is completed.
