Plating knitting method Plating knitting involves knitting using two yarns for each course of the knitted fabric, one of which is positioned on the front side of the knitted fabric and the other on the back side. When the yarns are of different colors, different colors are provided on the front and back sides of the knitted fabric.

In this knitting method, the front yarn (white yarn) is determined assuming that the carriage has moved leftward using a two-lock carriage.
Is knitted by the preceding cam lock for needle knitting, and the back thread (black thread) is knitted by the cam lock for needle knitting (both front and rear sides only). However, it is also possible to perform one course of plating knitting by performing two strokes with a carriage of one lock.

The examples shown in FIGS. 14 to 21 are examples in which the front needle 4F is used to knit each course in flat knitting so that white yarn appears on the front of the knitted fabric and black yarn appears on the back. In FIG. 14, 81,
82 indicates a loop of the previous course (referred to as a first course 83) already knitted, 81 indicates a white front thread, and 82 indicates a loop of a black thread. The loops 81 and 82 are engaged with the needle 4F of the front needle bed 3F in the aligned state.

The needle 4F is raised (FIG. 15) for knitting of the second course 84 (shown in FIG. 21), and the surface yarn 85 of the second course 84 is raised.
Feed. Loops 81 and 82 of the first course 83 are needle 4
Tongue 66 of slider 8 rising with the rise of F
(FIG. 16). Next, the slider 8 stops at the position as it is, and only the needle body descends. The front thread 85 is hooked on the hook 9 of the needle 4F while the loops 81 and 82 of the first course 83 are locked on the tongue 66 of the slider 8 and the slider 8 is moved. In step 8, only the needle body 51 is lowered while stopped, and the front thread 85 of the second course is drawn into the loops 81 and 82 of the first course 83 (FIGS. 17 and 18).

Next, the loop of the first course 83 is provided on the tongue 66 and the second
The front thread 85 of the course 84 is locked, and only the needle body 51 is raised to the tack position, and the back thread 8 of the second course 84 is newly added.
6 (black thread) is received (FIG. 19), the front and back threads 85 and 86 are engulfed in the hook 9, and the needle body 51 is lowered. The loops 81 and 82 of the first course 83 are locked to the tongue 66, but the hook 9 contacts the tongue 66 of the slider 8 and the hook 9 is closed by the lowering of the needle body 51 (FIG. 2).
0), the hook 9 is moved by the lowering of the slider 8 and the needle body 51.
Go through the loops 81 and 82 of the first course 83, and within the loops of the first course 83, the loops 85 and 86 of the second course 84
(FIG. 21). This is repeated below.

Pile knitting method In order to knit a pile knitted fabric according to the method of the present invention, needles of front and rear needle beds are used. In the method of the present invention, a carriage consisting of three locks of preceding, middle, and succeeding is used, and assuming that the carriage has moved to the left, the tightening yarn is knitted by the cam lock for needle knitting acting on the preceding front needle side, and the pile yarn is knitted. And knitting with a cam lock for needle knitting acting on the needles on the front and rear sides of the middle row. The pile loop is knitted by the needle knitting cam lock acting on the rear needle on the following line. Details will be described below. First, the initial process of knitting is the same as the above-described plating knitting shown in FIGS. 14 to 17 (however, the surface yarn 81 in FIG. 17 is a tightening yarn 91 described later).
As shown in FIG. 22, the tightening thread 91 (white) and the pile thread 92 (black)
Thus, the aligned loops 94 and 95 of the first course 93 are formed on the needle 4F of the front needle bed 3F, and the first course 9 is formed.
The third loops 94 and 95 are engaged with the tongue 66 of the slider 8. Then, the needle 4F is raised to supply the tightening thread 97 (white) of the second course 96 to the hook 9 of the needle 4F.

The needle 4F having received the supply of the tightening thread 97 of the second course is placed on the first course 9 while the slider 8 remains in the same position.
3 stops with the loops 94 and 95 locked, and the needle
1 is lowered and the hook 9 is used to tighten the thread 9 of the second course.
7 is drawn into loops 94 and 95 of the first course. The retraction of the hook 9 is minimized. At the same time, the tongue 66 of the slider 8 is set at a position higher than the hook 9 so that the loops 94 and 95 of the first course 93 do not knock over (FIG. 23).

Next, the pile yarn 98 of the second course 96 is supplied. With the position of the tongue 66 of the slider 8 held as before, the front needle 4F is raised to the tack position and the supplied pile thread 98 (black) is hooked. At the same time, the rear needle 4B also rises and crosses the hooks 9, 9 (FIG. 24).
Next, both needles 4F and 4B are lowered (performed with the middle knitting cam), but only the pile thread 98 (black) is hooked on the hook 9 of the rear needle 4B and pulled down, and the pile is hooked on the hook of the front needle 4F. The thread 98 (black) and the fastening thread 9 7 (white) are locked together and pulled down (FIG. 25), and the loop 99 of the fastening thread 97 of the second course 96 and the loop 100 of the pile thread 98 are moved to the first Course 9
The loops 94 and 95 of the third tightening thread 91 and the pile thread 92 are passed through (FIG. 26).

As a result, the pile yarn 98 forms a loop (or stitch loop) in a state of being aligned with the tightening yarn 97 by the front needle bed 3F, and the pile yarn 98 is engaged with the hook 9 of the rear needle 4B to form the pile 101. Pulled out (FIG. 26). Next, the needle main body 55 and the hook 9 of the rear needle bed 3B are raised by the cam operation lock 7 on the rear side of the rear carriage (FIG. 2).
7) The needle main body 55 is lowered while the pile 101 is locked on the step portion 65 of the slider 8 and the hook 9 is tongue 66
Then, the pile 101 locked to the rear needle 4B is wiped off by lowering with the hook closed (FIG. 28). The pile knitted fabric is knitted by repeating the above knitting.

[0046]

According to the stitch knitting method of the present invention, when the needle holding the stitch loop on the hook advances to the knitting position, pulls in the supplied yarn, and retreats, the old loop does not knock over the tip of the slider. In this way, the slider is advanced over the tooth gap beyond the hook, and in this state maintained, the slider is guided to the subsequent knitting part such as the knitting lock,
Since the required knitting operation is provided in the subsequent knitting section, it is possible to increase the number of splits and to form a new stitch such as a playing knitting or a pile knitting.

According to the present invention, when the needle is raised and the yarn to be fed into the new loop is bitten into the hook to pass through the old loop,
The old loop is held at a predetermined height by the tongue of the slider, so the new loop does not come into strong contact with the old loop or receive friction or resistance such as the old loop supporting the weight of the new loop. A new loop can be created, and the new loop does not twist in a specific direction and can have a symmetrical center.

Since there is no friction or resistance as described above, when a large number of split loops are formed on the same course, it is possible to suppress the occurrence of distortion in the wale direction of the conventional knitted fabric, In the case of the playing knitting, the loops on the front and back sides are aligned so that the opposite color does not spread to the front or back side, and even in the case of the pile knitting, the pile loops can be aligned at the same time.
