The lower surface of the sub-carriage 33 has an upper plate 35 for forming an upper body needle passage, a lower plate 36 for forming a lower body needle passage, and an abbreviated character shape between the two plates 35° and 36. The knitting cams 37 are arranged, the opening/closing cams 38 are pivotally attached to the rear ends of the knitting cams 37 so that they can be flipped forward, and the auxiliary retracting cams 39 are tilted inside the knitting cams 37. is provided.

Each of the auxiliary retraction cams 39 is provided with a main retraction surface 40, a stepped portion 41 for temporarily stopping the retraction of the butt of the fine knitting needles 6, and a sub-retraction surface 42 for restarting the retraction.

The above cam arrangement forms a knitting path P3 for guiding the butt of the fine knitting needle 6 during knitting, as shown by the dashed line in FIG.

This embodiment is configured as described above.

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

That is, the main knitting needles that will participate in knitting are sorted in advance into the front main knitting needles 3A at needle selection position Y and the back main knitting needles 3B at knitting preparation position X, and all of the fine knitting needles 6 that will participate in knitting are prepared for knitting. In addition, the first knitting yarn T1 is inserted through the front yarn opening 27, and the second knitting yarn T2 is inserted through the rear yarn opening 28, respectively.

Therefore, the main character, Gekiga Carriage I, 33, is shown in Figure 1 and Figure 3 A.
By sliding in the direction of the arrow shown in FIG. 3B, the butt of the front main knitting needle 3A is placed in the front knitting path P1, the butt of the back main knitting needle 3B is placed in the back knitting path P2, and the fine knitting needle 6 is moved in the direction of the arrow shown in FIG. 3B.
The bats are introduced and guided into the knitting path P3, respectively.

Thus, these knitting needles 3A, 3B, 6 are connected to the front and rear thread openings 27.
For example, when passing the position 28, the front and rear main knitting needles 3
A and 3B have the first and first knitting yarns T1,
After T2 is supplied separately (Fig. 3A, B).

(see Fig. 4 A, B, Fig. 5 A, B), the knitting cam 13 retreats to the rear of the knockover position and knits 2 in the new first and second knitting stitches Kl (see Fig. 6). reference).

This knitting is a so-called two-color simultaneous knitting knitting.

On the other hand, among the fine knitting needles 6, for example, the fine knitting needle 6 (third

As shown in B, the main retraction surface 40 of the auxiliary retraction cam 39
When the latch starts to be retracted by the hook, the open latch tip is placed under the knitted fabric pressing plate 29, and the second knitting yarn T2 lies between the open latch tip and the hook, When it is retracted to the end, the hook catches the second knitting yarn T2, and the latch is rotated in the hook closing direction by the knockover preparation action of the old knitting mill (not shown), so that its tip touches the knitting fabric presser plate. Touches the bottom surface of 29 (
(See Figure 5C).

Next, the retraction of the fine knitting needles 6 is temporarily interrupted by the stepped portion 41 of the auxiliary retraction cam 39 (during this interruption of retraction, the front and rear main knitting needles 3A.

3B is retracted until its hook tip corresponds to approximately the back surface of the fine knitting needle 6, but this is done at this time because the front main knitting needle 3A is closed by the closed latch as shown in FIG. 3B, for example. If the second knitting yarn T2 is lying on top, and the second knitting yarn T2 is pulled downward by the hook of the fine knitting needle 6, the second knitting yarn T2 will be stretched or the knitting resistance will increase. (This is to prevent this from occurring.)

Furthermore, at this time, the first knitting yarn T1 is on the slope 3 of the rising protrusion 30.
1 is located slightly above and in front of the 5th
(See Figure C).

Subsequently, when the fine knitting needle 6 is retracted by the sub-retreating surface 42 of the auxiliary retracting cam 39, the hook is moved to the second knitting yarn T2.
The latch tip of the first knitting yarn T1 descends below the knitting yarn T1 while being caught, and the tip of the latch is attached to the knitted fabric pressing plate 29 by the notch 32.
release from the underside of the hook and close the hook (see Figure 5C).

Further, the fine knitting needles 6 are moved back by the knitting cam 3T, so that a new stitch 3 is knitted using only the second knitting yarn T2 (see FIG. 6).

Also, among the fine knitting needles 6, the fine knitting needles 6 adjacent to the front main knitting needle 3A on the rear side in the carriage sliding direction are shown in FIGS. 3B and 5A.

As shown in B and C, by being retracted by the main retraction surface 40 of the auxiliary retraction cam 39, the hook moves to the first position.
, both of the second knitting yarns Tl and T2 are caught, and the tip of the opening latch engages with the lower surface of the knitted fabric pressing plate 29 (see FIGS. 3B and 5C).

Subsequently, when the fine knitting needle 6 is retracted by the auxiliary retraction surface 42 and the knitting cam 37 via the stepped portion 41 of the auxiliary retraction cam 39, the latch is released from the lower surface of the knitted fabric pressing plate 29 by the notch 32, and the hook is released. After closing (Fig. 5C)
), the old plating stitch WKI is knocked over and a new plating stitch WK2 is knitted by both the above-mentioned braided yarns Tl and T2 (
(See Figure 5C).

In this case, when knitting the new plating stitch WK2, the third
As shown in FIG. B and FIG. Since it is arranged on the main needle bed side with respect to knitting yarn T2, after knitting, as shown in FIG.
The stitch WK2A created by the second knitting yarn T2 is exposed on the surface side of the knitted fabric, and the stitch WK2B created by the second knitting yarn T2 is hidden inside the fabric (both stitches WK1A and WKIB of the old plating stitch WK1).
(see also).

By the above method, knitting of courses is performed in sequence, and after the batts of the front and rear main knitting needles 3A and 3B are once merged, the front and rear knitting needles are sorted into a new pattern for the next course by the needle selection cam mechanism.

In order to knit the next course, it is sufficient to turn back and slide both carriages 7°33.
A, 3B, and each fine knitting needle 6 adjacent to these knitting needles 3A, 3B on the rear side in the carriage sliding direction (fine knitting needles adjacent to the left and right sides opposite to the above), in the same manner as above. The organization is made by

By repeating knitting as described above, the outline of the line pattern on the surface of the knitted fabric knitted with the fine knitting needles 6 will be slightly increased. The line pattern formed by the second knitting yarns TI and T2 appears in substantially the same way on both the front and back sides of the knitted fabric.

Since the present invention knits a double-sided knitted fabric using the method detailed above, the pattern of each line pattern by the first and second knitting yarns knitted on the main needle bed side is determined by the sub needle. It is possible to knit and express the knitted surface in approximately the same pattern on the knitted surface knitted on the floor side,
This double-sided knitted fabric can be knitted easily and accurately.

In addition, since only the second knitting yarn is supplied to each of the fine knitting needles adjacent to each of the rear main knitting needles and the first knitting yarn is not supplied, the knitted fabric of this portion is It is possible to provide a double-sided knitted fabric that can be made thinner and has a good overall appearance and wearability.
