The number of stitches is displayed smaller than the actual knitting.

  The knitting of the intermediate portion 6 will be described below using the knitting steps S1 to S8. In S1, as the end stitch row of the first tubular portion 3 on the toe side, the new yarn is formed using the yarn feeder 11 at the stitch engaged with the knitting needles E to L of the FD. In S2, as the end stitch of the first tubular portion 3, the advancing direction of the yarn feeder 11 is changed to the stitch engaged with the knitting needles l to e of the BD to form a new stitch. Further, the first knitted fabric is formed into a tongue by alternately forming turns from the knitting needle D of the FD using the knitting needles D of the FD adjacent to the knitted fabric, the knitting needles d of the knitting needles A and the knitting needles d of the BD and the empty needles of the knitting needles a. Perform part 7 knitting. In S3, the stitches of the front and rear needle beds formed in S2 are transferred one by one to the right, and a stitch is formed on the knitting needle E of FD and the knitting needle e of BD. Further, the yarn feeder 11 is moved to the right to form a stitch which becomes an additional stitch on the knitting needle A of the FD and a new stitch on the knitting needle B to the knitting needle E.

  In S4, a new yarn feeder 12 is inserted from the left and moved to the right, and the stitch on the knitting needle a of the BD, which is the end of the knitted fabric on the opposite side, is expanded and the knitting needles b to e Form a new stitch. By these steps S2 to S4, the first knitted fabric portion 7 to be a tongue is unfolded (S2), and yarn feeders different in FD and BD are used to move in the direction of the tubular knitted fabric so as to bifurcate the unfolding. Furthermore, a new stitch is formed by left-right reciprocating knitting, and is joined to the end stitch of the first tubular portion 3 (S3, S4). In S5, the two yarn feeders (11, 12) are respectively moved leftward to form new stitches in the stitches engaged with the knitting needles E to B of the FD and the knitting needles e to b of the BD. In S6, the state after repeating the process similar to S3-S5 mentioned above twice is shown. The first knitted fabric portion 7 is formed by the above-described knitting.

  In FIG. 3, although the number of stitches is smaller than the actual knitting and not shown, the five cord holes shown in the first knitted fabric portion 7 shown in FIGS. 2, 4 and 5 are, for example, after the knitting of S5. A stitch to be locked at a position where a cord hole is to be formed is moved to the left or right to provide a double stitch and an empty needle, and a hollow needle is hooked and then a new stitch can be formed. Further, the area 17 of increase or decrease divided by the alternate long and short dash line shown in the first knitted fabric part 7 is similarly formed using the movement of the stitches in the formation of S5. Specifically, in the case of the increase in FIG. 2, the stitches may be moved to provide an empty needle, and the empty needle may be hooked, and then a new stitch may be formed, and in the case of the reduction in FIG. It may be moved to form a lap, and then a new stitch may be formed. If such organization is carried out in a plurality of courses, it can be molded.

In S7, the stitches engaged with the knitting needles L to H of the FD and the knitting needles l to h of the BD as the end stitch row of the first tubular portion 3 are the left direction opposite to the moving direction of the first knitted fabric part 7 By moving one stitch each, stitches can be formed on the knitting needles G of the FD and the knitting needles g of the BD, and can be joined to the right side end of the first knitted fabric portion 7. At this time, since the stitches in the course direction of the second knitted fabric portion 8 are joined to the stitches in the wale direction of the first knitted fabric portion 7, the wales of the stitches in the two regions are orthogonal. In S8, a new stitch is formed on the stitches engaged with the knitting needles H to L of the FD, and the first knitted fabric portion 7 and the second knitted fabric portion 8 are joined at the position of the lap. Although not shown, new stitches are subsequently formed on the stitches to be locked to the knitting needles h to l of the BD, and knitting similar to S7 and S8 is performed, and the knitting needles A to C of the FD and the knitting needles a to BD The process is repeated until the hooks to be locked to the knitting needle c are left, and the intermediate portion 6 is completed.
