Further, as shown in FIGS. 10 and 17, the thread opening 76 and the latch engagement plate 78 are moved up and down according to the cam shape of the ninth drive cam 165. That is,
Due to the action of the small diameter portion 165c of the ninth drive cam 165, the thread opening 76 is placed in the upper position, and the latch engagement plate 78 is placed in the lower position, so that the latch 4
c is prevented from rotating toward the hook 4b. This prevents the stitches on the main needle 4 placed at the flattened position from falling off (FIGS. 8 and 9 in FIG. 17). Also,
Due to the action of the large diameter portion 165a of the cam 165,
The yarn opening 76 is placed in the lower position to prevent the knitting yarn Y supplied to the sub needle 63 from falling off, and the latch engagement plate 78 is placed in the upper position to allow rotation of the latch 63b due to knockover. (Figure 17, 10).

Further, as is clear from FIGS. 8, 9 and 17, the thread opening 76 and the latch engagement plate 78 are moved left and right according to the cam shape of the eighth drive cam 161. That is, after the thread head 76 is moved from the right side of the secondary needle 63 to the left side by the action of the small diameter portion 161b of the eighth drive cam 161, the thread head 76 is moved to the left side of the secondary needle 63 due to the action of the large diameter portion 161a. The yarn is then moved to the right, and the yarn feeding operation is performed (FIG. 17, 9). moreover,
During this knitting operation, when the drive cam body 112 is rotated approximately 270 degrees, as is clear from FIGS. 18a and 18b and FIG. 17, the cam contact pin 101
a is engaged with the chevron portion 170b of the tenth drive cam 170, and the switching member 181 is moved to the right (FIGS. 13-17). Based on this rightward movement of the switching member 181, the armatures A1 to A6 are aligned in the non-engaging position by the leaf spring 184, and the cylindrical support 14 is aligned by the action of the cam surface 182b.

b, 140a, 137a is canceled, and each cam contact pin 147a, 163b, 140
a, 137a are all placed in the upper position. As a result, the cam contact pin 140a of the tack control lever 140 is switched from the lower position to the upper position, and the cam contact pin 140a of the secondary needle operating lever 147 is switched from the lower position to the upper position.
7a is switched from the intermediate position to the upper position, and the tack control lever 140 is connected to the first drive cam 13.
The secondary needle operating lever 147 is pivoted integrally with the single needle operating lever 137, which is operated by Since the range is regulated, it does not interfere with the knitting operation.

In addition, based on the rightward movement of the switching member 181, the feed switching plate 93 is moved rightward, and the armatures A7 and A8 are aligned and arranged in a non-engaging position via each guide member 198. After that, each electromagnet S1 to S is activated by a predetermined electric signal for the next knitting operation.
8 is selectively excited.

To summarize the above, as is clear from FIGS. 2, 17, and 26, after the main needle 4 is moved forward to the latch removal position, the latch engagement plate 78 is lowered and the main needle 4
The latch 4c is attracted and held in the open state by the permanent magnet 79 (FIG. 17, 4), and after the main needle 4 is rotated and both needles 4 and 63 are connected, the latch engagement plate 78
As the needles 4 and 63 rise, both needles 4 and 63 are moved backward in a connected state, and the stitches on the main needle 4 are transferred onto the sub needle 63 (FIG. 17, 6). The latch 4c of the main hand 4 is attracted to the permanent magnet 80 and held in an upright position. Thereafter, the secondary needle 63 enters the needle groove 2 of the needle bed 1 to perform a latch removal operation, and the latch engagement plate 78 is lowered to prevent the secondary needle 63 from rotating in the closing direction of the latch 63b. (Fig. 17, 8). Thereafter, the thread opening 76 is moved from the left side to the right side of the secondary needle 63, the knitting yarn Y is supplied to the secondary needle 63, the latch engagement plate 78 is raised, and the secondary needle 63 is moved to the knockover position. A new stitch is formed on the secondary needle 63 (17th
Figures 9 and 10). Subsequently, the latch engagement plate 78 is lowered and the secondary needle 63 moves up and down and rotates, and then the main needle 4 is moved back and forth, but since the secondary needle 63 is not moved back and forth, both needles 63 are recombined and the secondary needle The new stitch on 63 is not transferred to main needle 4,
The stitches of the sub needle 63 are suspended at a position opposite to the end needle 4.

Next, when knitting with the main needle 4 following the end needle 4 is performed, as shown in FIG.
7 and S8 are both excited, and Fig. 15a and Fig. 16
As shown in Figure a, the armatures A7 and A8 are disposed in the non-engaging position, and the feed switching plate 93 is disposed in the left position. Therefore, as the drive cam body 112 rotates, the carriage 8 is moved to the right by the pitch of the main needle 4 by the action of the tenth drive cam 170. And, as mentioned above, FIG. 17
- 14, the secondary needle 63 is not reciprocated back and forth, so the new stitch on the secondary needle 63 is transferred to the main needle 4.
The stitch is not transferred to the end needle, but is suspended from the sub needle 63 at a position opposite to the main needle 4 following the end needle.

Therefore, by continuing to knit with the end needles and the main needle 4 following the end needles, it is possible to reduce the number of stitches by five stitches.

As shown in FIG. 35, after the five-stitch reduction is completed, the rear electromagnet 126b shown in FIG.
