The outer pile sinker 1, together with the inner pile sinker 2, is disposed in one sliding groove in a sinker cylinder (not shown). The external pile sinker 1 has a thick belly 11, a thin throat 12, a short nose 13 and a butt 14 near its rear side. . By the shape of the neck 12 and the nose part 13, the outer pile 8 and the base yarn 10 can work smoothly with the lower needle, and they can not be joined together to form a loop or a loop. Will not.

The inner pile sinker 2 has a thin valley 21, a thick neck 22, a long nose 23, a coupling 25 and a rear side pivoted against the selection jack 4 at its rear side. Butt 24 is provided. By the shape of the nose portion 23, the inner pile 9 and the base yarn 10 can operate together with the lower needle, and are joined together to form a loop or not to form a loop.

The sinker cap 3 is provided with two guide tracks 31 and 32 for driving the outer pile sinker 1 and the inner pile sinker 2 to form a pile loop. The selection jack 4 is one of the selection jack sets of the circular knitting machine, which is a front side pivoted with respect to the coupling portion 25 of the inner pile sinker 2, a projection 41 protruding at an appropriate position, The butt 42 near the rear side is provided.

The selector 5 is a computer controlled or electromagnetic valve type selector with a plurality of selector levers 51. The push cam 6 is provided with the actuating part 61. When the selector 5 is not pressed by the protrusion 41 of the selection jack 4, the butt 42 of the selection jack 4 moves along the actuating portion 61 of the cam 6 to select the jack. (4) to be pushed into the loop locking area.

The reset mechanism 7 is composed of a spring plate arranged behind the selection jack 4, and has a curved portion 71 pressed on the cylinder wall 101 of the sinker cylinder. When the selector 5 is operated, the selection jack 4 can be pressed. When the select jack 4 is pressurized, the reset mechanism 7 is urged against the cylinder wall 101 so that a reset action occurs and thus the select jack extends out so that a subsequent jacquard knitting cycle can proceed. The selection jack 4 extends out of the face of the needle cylinder, causing the projection 41 to bring the push cam 6 into preparation for the subsequent jacquard knitting cycle.

Jacquard organization consists of seven steps. In general, the outer pile sinker 1 and the inner pile sinker 2 move along the track in the sinker cap 3. When the selector 5 is actuated, the outer pile sinker 1 and the inner pile sinker 2 move along the track in the push cam 6. The seven steps will be described with reference to FIGS. 5A to 5J.

In the first step, as shown in Fig. 5A, following the final sinker ring, the knitting needles 1A move upwards and three loops 8, 9 hooked to the hooks of the knitting needles 1A. 10 pushes open latch 2A of knitted needle 1A, and inner pile sinker 2 and outer pile sinker 1 are pushed forward to keep the old loop down. If the knitting needle 1A continues to rise until it reaches the supply plate 3A, the latch 2A is completely open to release the loop held. When the latch 2A is fully open, the knitting needle 1A reaches the top position. When the work of keeping the fabric down is completed, the inner pile sinker 2 and the outer pile sinker 1 move backwards (also, the outer pile sinker 1 can pull the base yarn firmly, The neck of (1) presses the pile loop for a predetermined time, so the sinker timing in this step is relatively longer).

In the second step, as shown in Fig. 5B, the knitting needle 1A moves downward to be in the yarn hook position, and the inner pile sinker 2 and the outer pile sinker 1 move backwards so that the yarn inner pile The neck 22 of the sinker 2 and the neck 12 and the nose 13 of the external pile sinker 1 are released so that the pile loop slips into it. The internal pile 9 slides into the nose portion 23 of the internal pile sinker 2. The external pile 8 slides through the neck 12 of the external pile sinker 1 into the slot of the sinker or from the slot of the sinker.

The third step is to allow the file loop to be actively located, as shown in FIG. 5C. In the third step, the knitting needles remain in the half stitch position, the latches 2A are suspended about 0.5 mm high below the belly portion 11 of the outer pile sinker 1, and the outer pile sinker 1 and the inner The pile sinker 2 is moved toward the tuck position so that the hook of the knitting needle can hook the external pile 8, and the base yarn 10 is connected to the nose portion of the external pile sinker 1. 13) and the neck 22 of the inner pile sinker 2, so that the inner pile 9 is installed in the neck 12 of the outer pile sinker 1.

In the fourth step, as shown in Fig. 5D, the external file sinker 1 moves in the direction of forming the external file loop, and the computer sends a signal to the selector 5 so that the corresponding selection lever 51 selects it. Pressing or not pressurizing the jack 4 allows accordingly to determine whether the inner pile 9 is to be knitted in a pile loop or in a non-filing pattern. When creating a pile loop (see FIGS. 5E and 5F), the selection lever 51 does not touch the protrusion 41 of the selection jack 4, and the butt 42 of the selection jack 4 is the cam 6. Moving forward along the actuating portion 61, the yarn is pulled by the lower knitting needle to form a pile loop. In the case of generating a non-filing pattern (see FIGS. 5G and 5H), the selection lever 51 is pressed at the protrusion 41 of the selection jack 4, causing the reset mechanism 7 to cause the cylinder wall 101 of the sinker cylinder. To pressurize against. Thus, the butt 42 of the selection jack 4 is moved beyond the actuating portion 61 of the cam 6 so that the inner pile sinker 2 and the lower knitting needle do not create a pile loop. In this step, only the base yarn 4 is pushed out of the needle cylinder by the reset mechanism 7 before the subsequent knitting cycle.

In the fifth step, as shown in FIG. 5I, the inner pile 9 is pushed out of the actuating portion 61 of the cam 6 and pulled by the lower knitted needle 1A to form a pile loop. Lose. In the fourth step, a file loop or non-file pattern formation operation has already been determined. In the fifth step, the lower knitted needle 1A is driven to hook the loop down. The yarn loop is fed to the neck 12 of the outer pile sinker 1, and the outer pile 8 is released for a predetermined time after the sinker is pushed out so that the lower knitted needle 1A hooks the loop down. do.

In the sixth step, as shown in Fig. 5J, the lower knitting needle 1A pulls the loop down, and the inner pile 9, the outer pile 8 and the base yarn 10 are shown. When the inner pile sinker 2 is pressed, the sinker is not pushed out, at which time no pile loop is created and only the base yarn is visible.

In the seventh step, as shown in FIGS. 4A and 4B, the lower knitting needle 1A completes the loop and prepares for the subsequent knitting cycle, while at the same time the inner pile sinker 2 and the outer pile sinker ( 1) is pushed to keep old files down.

As discussed above, the selection jack 4 is pivoted with respect to the internal pile sinker 2 and controlled by the selector 5 to work with the push cam 6, so that the internal pile is piled during the double loop towel knitting operation. It is organized to form a loop or non-filing pattern.
