At the time of the 413th lap, the third shuttle of the third way goes down, and at the 78th stitch, the needle starts to eat the yarn of the third shuttle of the third way. At the 413th round, the knitting range of the third stitch is from the 78th stitch to the 120th stitch and from the 1st stitch to the 43rd stitch. At the 413th lap, the third shuttle of the second road, the third shuttle of the fourth road, and the third shuttle of the third road were dropped almost at the same time. The knitting area of the second road is from the 42nd needle to the 61st needle, the knitting area of the fourth road is from the 60th needle to the 79th needle, and the knitting area of the third road is the same as the 78th needle to the 120th needle Go to the 1st needle and continue to the 43rd needle. According to the distribution of this work area, all do forward and reverse reciprocating motions for 6 circles. Starting from the 419th lap, the working area of the third road remains unchanged, the stitching work area of the second road and the fourth road, and the part connected to the third road remain unchanged, and the needle number area on the opposite side is in the shape of Decreasing trend, showing an inverted V shape. The detailed description of this decreasing trend text is as follows: At the 419th circle, the stitch number area of the third way remains unchanged, the stitch number area of the second way changes from 42-60 to 42-59, and the stitch number area of the fourth way changes from 60- 79, becomes 61-79, wherein the 60th needle cannot afford the needle or thread. On the 420th lap, the third road remained unchanged, the second road area was 42-61, and the fourth road was 63-79, of which the 62nd needle could not be needled. The 421st lap is the same as the 419th lap. The 422nd lap is the same as the 420th lap. On the 423rd lap, the second road was 42-60, and the fourth road was 61-79. On the 424th lap, the second road was 42-59, and the fourth road was 62-79. On the 425th lap, the second road was 42-60, and the fourth road was 61-79. Every four circles is equivalent to a cycle. As above, in every four circles, there is a small cycle with odd and even lines. The 425th circle - the 428th circle, the 429th - 432nd circle, ... In this way, the area of the second road decreases to the left, and the area of one stitch decreases to the left every four circles. In these four circles, the odd-numbered rows are farthest to the right No stitches are needed, and the rightmost side of the even-numbered rows is one and a half stitches more than the rightmost side of the odd-numbered rows, which plays the role of connection reinforcement. The area of the fourth road decreases to the right direction, and the area of one stitch decreases to the right every four circles. In these four circles, there is one and a half more stitches on the leftmost side of the even-numbered rows than the leftmost side of the odd-numbered rows, which can strengthen the connection. role. The knitting area of the second and fourth roads is from the 413th circle to the 476th circle, and a total of 64 circles are knitted. At the 476th lap, the second and fourth weaving ends and the shuttle is withdrawn. At this time, during the 476th circle, the knitting area of the second road is the 42nd-45th stitches, and the knitting area of the fourth road is the 76th-79th stitches.

At the 477th round, continue knitting in the third way, with 1-44 stitches on the left and 78-120 stitches on the right, and the number of stitches decreases by two stitches every two rows. The left area of the third way decreases to the left, and the right area of the third way decreases to the right. For example, in the 477th circle, the leftmost stitch of the third road is 1-44, and the right is 78-120. The last stitch on the far right of the even-numbered row on the left is the half-position needle of the third road, and the last stitch on the leftmost of the odd-numbered row on the right is the half-position needle of the third road. . For every two rounds of a loop, decrease two stitches to the left and right respectively. Lap 477 left 1-44, right 78-120, lap 478 left 1-45, right 77-120. Lap 479 left 1-43, right 79-120, lap 480 left 1-41, right 81- 120 stitches. By analogy, the area weaving of the third road ends when the 516th lap is completed. At this time, on the 516th lap, the number of stitches in the left area of the third road is 1-7, the number of stitches in the right area is 114-120 stitches, and the number of stitches in other areas does not afford needles or threads. At the 517th lap, the 3rd shuttle of the 2nd road and the 3rd shuttle of the 4th road were under shuttle work. From the 28th needle to the 28th needle, the needle starts to eat the thread, 28-32 needles, the fourth road is from the 88th needle to the 93rd needle, the 518th circle, the second road is 27-34, the fourth road 87-94, lap 519, second road 26-34, fourth road 86-94, lap 520, second road 25-36, fourth road 85-96, lap 521, second road 24-36 , the fourth road 84-96, the 522nd lap, the second road 23-38, the fourth road 83-98, the 523rd lap, the second road 22-38, the fourth road 82-98, the 524th lap , the second road 21-40, the fourth road 81-100, on the 525th lap, the second road 20-40, the fourth road 80-100, on the 526th lap, the second road 19-42, the fourth road 79 -102, .... and so on. At 542 laps, the work of the second and fourth routes is completed and the shuttle is withdrawn. At this time, the 8th needle in the area of the second road - the 56th needle, and the 76th needle - 113 needles in the area of the fourth road. Round 543 - the end of the entire sock toe is round 546, which is the seam thread. As for the waste yarn machine head thread, it is not shown in this picture, and it is in the chain program file.
