The method of knitting the double-sided knitted fabric will be explained below.

Specifically, by sliding both carriages 8° 23 in one direction, the base yarn T1 is transferred to the main knitting needle (hereinafter referred to as the rear main knitting needle 2X) at the knitting preparation position X involved in knitting the fabric. The colored yarn T2 is supplied to the main knitting needles at needle selection position Y (hereinafter referred to as front main knitting needles 2Y) to knit stitches together, while the carriage sliding direction is applied to each of the front and rear main knitting needles 2Y and 2X. The base thread T1 and the colored thread T2 are supplied to each of the sub-line needles (hereinafter referred to as 6Y and 6X) adjacent to the rear side to knit two stitches at the same time, and among the two stitches, each sub-line needle is Line needle 6Y,
The front and rear main knitting needles 2Y adjacent to 6X as described above
, 2X is made to expose only one stitch made of the same knitting yarn as the knitting yarn of the stitch knitted on the knitted fabric surface, and as shown in Fig. 4, the knitting on the main knitting needle side The pattern shape is made to appear in an orderly manner on the ground, and the outline of the same pattern shape is blurred and appears in substantially the same state on the knitted surface on the side of the sub-line needle.

The details of the operation will be explained below. First, the front and rear main knitting needles 2Y and 2X are sorted into the respective positions X and Y (see A in Fig. 3), and each of the sub-line needles 6Y and 6X is selected in advance. is placed in the knitting preparation position, and the small hole thread [ko 35 is the ground thread T]
1 and the colored threads T2 are inserted through the horizontally long thread openings 36, respectively.

After that, by sliding both the connected carriages 8 and 23 in one direction (the direction of the arrow shown in A in FIG. 3),
Until the main and sub-knitting needles reach the center of each carriage, the rear main knitting needles 2X guided to the rear knitting path X-Z are advanced beyond the flat removal position by the back surface of the knitting cam 13. At the same time, with the latch 2XR erected by the magnet 42 and prevented from falling forward by the thread opening plate 34, the latch 2XR is retracted by the inner part of the intermediate partition wall 11, etc. to a substantially flat position (B1 in FIG. 3). reference).

Further, regarding the front main knitting needles 2Y guided to the front knitting path Y-Z, the switching cam 17 etc. advances the flattening needle 2Y beyond the flat removal position, and the opened latch 2YR
It enters the lower side of the lower flat plate of the thread opening plate 34 while being held down by the thread opening plate 34 (see B2 in FIG. 3).

On the other hand, for the sub-line needles 6Y and 6X adjacent to the front and rear main knitting needles 2Y and 2X on the rear side in the sliding direction of the carriage, the knitting cam 26 advances the flat puller beyond the position, and Latch 6YR.

6XR is pressed down by the brush 41 on the way (8 in Figure 3).
1. (See B2).

Next, each of the knitting needles 2Y, 2X, 6Y, 6X is connected to C in FIG.
Corresponding to the positions, the front part of the rear main knitting needle 2X is raised by the rising protrusion 39 and the ground yarn T1 is wrapped around its hook, and the front main knitting needle 2Y is
The colored thread T2 is wrapped around the hook in a state where the front part is raised by the one-lifting protrusion 39 while being slightly retreated (
(See CI, C2 in Figure 3).

On the other hand, the sub-line needles 6Y and 6X remain in the same state as described above.

(See CI, C2 in Figure 3).

Subsequently, when each of the knitting needles 2Y, 2X, 6Y, and 6X corresponds to position D in FIG. When closed, the front main knitting needle 2Y is retreated to the same position as the front main knitting needle 2X, and its launch 2YR closes the hook with the old knitting opening K (Dl in FIG. 3).

(See B2).

At this time, the base yarn T1 lies on the closing latch of the front main knitting needles 2Y, and the colored yarn T2 lies on the lower side of the rear knitting needles 2X.

On the other hand, the sub-line needles 6Y, 6X are retracted by the knitting cam 26, and their respective latches 6YR, 6XR engage with the lower surface of the knitted fabric presser plate 37, causing the latches 6YR, 6
The hook closing effect by XR is blocked (DI in Figure 3).
, see B2).

Subsequently, when each of the knitting needles 2Y, 2X, 6Y, and 6X corresponds to position E in FIG. The old knitting opening K is on the latch 2YR, 2XR-H, and the ground thread T
1. Colored thread T2 begins to be pulled backwards (El in Figure 3)
, see B2).

On the other hand, each of the sub-line needles 6Y and 6X is continuously moved backward by the knitting cam 26, and the base yarn T1 and the colored yarn T1 are placed in their respective hooks.
2 is placed, and its latches 6YR and 6XR are closed by the two old knitting openings WK.

In this case, the ground thread T1 is pulled by the hooks of the adjacent rear main knitting needles 2X and sub-line needles 6X, so
Within the hook of Because it is pulled, it is placed closer to the main knitting needle than the ground thread T1 in the hook of the sub-line needle 6Y (see B2 in Figure 3).
.

Furthermore, each of the knitting needles 2Y, 2X, 6Y, and 6X is F in FIG.
Corresponding to the position, front and back main knitting needles are 2Y.

2X is completely retracted by the knitting cam 13, and the sub knitting needles 6Y and 6X are completely retracted by the knitting cam 26, respectively, and the WK is knocked over to each of the old knitting openings, and the rear main knitting needles 2X are 1 for a new stitch using ground yarn T1, and 2 for a new stitch using colored thread T2 on the front main knitting needle 2Y.
However, in each of the sub-line needles 6y and 6x, a new stitch WK1 using the ground yarn T1 and a new stitch WK2 using the colored yarn T2 are knitted, respectively (see Fl and F2 in FIG. 3).

In this case, the stitches are knitted with the arrangement of the base yarn T1 and color thread T2 in the hooks of the sub-line needles 6Y and 6X remaining in the above-mentioned state, so the stitch WK1 is knitted in the sub-line needle 6X. The stitch WK2 is knitted on the main knitting needle side so that it is exposed on the surface of the knitted fabric only on the sub-line needle 6Y (see F1 in Fig. 3). It is knitted and arranged on the needle side (see F2 in Fig. 3).

In this way, the knitting of the courses is performed sequentially.

Therefore, when organizing the next course, both carriages 8 and 23
When the front and rear main knitting needles slide in the opposite direction, the knitting action is performed in exactly the same manner as described above, but the secondary line needles move backward in the sliding direction of the carriage relative to the front and rear main knitting needles. Sub-line needles adjacent to the sides (i.e., sub-line needles adjacent to the opposite side of the sub-line needle 6Y to the front main knitting needle 2Y, and sub-line needles adjacent to the opposite side of the sub-line needle 6X to the rear main knitting needle 2X) ), the knitting action is carried out in exactly the same manner as described above.

That is, the sub-line needle (corresponding to the sub-line needle 6X explained in the above course) adjacent to the opposite side of the sub-line needle 6Y with respect to the front main knitting needle 2Y has a new stitch WK made of the base yarn T1 and the coloring yarn T2.
1° WK2 is knitted and arranged on the main knitting needle side so that only the stitch WK2 is exposed on the surface of the knitted fabric, and the sub line adjacent to the side opposite to the sub line needle 6X with respect to the rear main knitting needle 2X The needle (corresponding to the subline needle 6Y explained in the above course) has a new stitch WK1. W
K2 is knitted and is knitted and arranged on the main knitting needle side so that only the stitch WK1 is exposed on the surface of the knitted fabric.

As a result, as shown enlarged in the upper circle of Figure 4,
At the boundary between other parts of the knitted fabric and the patterned part, the stitches WK2 forming the pattern appear shifted laterally by one stitch with respect to the course.

By repeating this knitting in sequence, the same line pattern shape appears neatly on one side of the knitted fabric (the front side shown in Fig. 4), as shown in Fig. 4 (knitted with main knitting needles 2Y and 2X). 1°K2) on the knitted stitches, and on the other side of the knitted fabric (the rear side shown in Figure 4), the outline of the pattern becomes uneven and appears blurred at first glance (knitted with subline needles 6xt6y). stitches WK1.WK2).

The patterned fabric knitted in this manner can be turned over and used on both sides as appropriate, depending on preference or purpose of use.

[Effects] As described in detail above, the present invention provides hooks for the main knitting needles in one of the main knitting needles that are involved in knitting a knitted fabric, each of which is once advanced to the flat removal position and then sorted into the front and back positions. A knitting yarn is supplied to the hook of the main knitting needle at the other position, and another knitting yarn is supplied to the hook of the main knitting needle at the other position, and both of the main knitting needles are retreated to the knockover position to knit one stitch for each knitting yarn. At the same time, each sub-line needle located correspondingly between each of the main knitting needles involved in knitting the knitted fabric is once advanced to the flattening position and then retreated so that its hooks are connected to the hooks of the main knitting needles that are in the process of retreating. The tubular knitting yarn is supplied to the hook at a time substantially corresponding to the direction in which the knitting needles are arranged, and at a time when the hook is placed immediately below the hook of the main knitting needle due to the continued retreat of the sub-line needle. , among the tubular knitting yarns in the hook, the same knitting yarn as the knitting yarn knitted by the main knitting needles adjacent to the predetermined left and right sides of the secondary line needles that received the tubular knitting yarns is used from other knitting yarns. is placed inside the hook along with other knitting yarns so that it is located on the main knitting needle side, and in that state, the subline needle is further retreated to the knockover position to knock over the old knitting opening on the subline needle. By simultaneously knitting two stitches using the tubular knitting yarn, one of the two stitches is knitted using the same knitting yarn as the stitch knitted by the main knitting needles adjacent to the predetermined left and right sides. Since only the stitches are exposed on the surface of the knitted fabric, the color scheme and shape of the braided structure made of each knitting yarn exposed on one side of the knitted fabric can be maintained in approximately the same state and the outline of the shape. It is possible to blur only the knitted fabric and make it appear on the other side of the knitted fabric.
Depending on preference, purpose of use, etc., both sides of the knitted fabric can be used as desired, especially while keeping the pattern shape the same.
