Below, embodiments of the present invention will be described based on FIGS. 1 to 3.

(Example)

In this embodiment, a method of knitting a punch lace knit fabric using a two-bed flat knitting machine is explained. A plurality of composite needles as knitting needles 1 are arranged on the needle bed 2 of the flat knitting machine. The carriage (not shown in the drawing) that travels back and forth on the needle bed includes a cam system 10 that moves the knitting needle 1 forward and backward, and a plurality of yarn feeding ports that feed knitting yarn to the knitting needle 1. (口) is provided. In addition, as the knitting needle 1, Japanese Patent No. 2917146, as the configuration of the presser or needle bed mounted on the cam system 10 or as a line needle mechanism, Japanese Patent No. 5057996, and as the loop presser 9 for pressing the knitting yarn, Since the equivalent of the known flat knitting machine disclosed in Japanese Patent No. 4102430, etc. can be applied, its description is omitted here.

<Knitting needles>

The knitting needle 1 is composed of a needle body 3 having a hook 7 at the tip, and a slider 5 that moves relative to the needle body 3 to open and close the hook 7. The needle body 3 and the slider 5 are each provided with butts, and under the action of the cam system 10, which will be described later, the needle body 3 and the slider 5 advance and retreat with respect to the needle bed gap. .

<Cam system>

Figure 1 is a diagram schematically showing the cam system 10 mounted on a carriage. The cam system 10 is configured to perform knit, tuck, and miss, but may also be a composite cam system capable of stitch transfer. Additionally, a plurality of cam systems 10 may be mounted on the carriage. The cam system 10 functions as a composite needle control means for controlling the advance and retreat of the needle body 3 and the slider 5 of the knitting needle 1.

Figure 1 shows the state when the cam system 10 travels to the left and performs knitting. The cam system 10 includes a presser unit 13 that acts on the butt of the select jack (not shown in the drawing), and a needle body control cam unit that acts on the butt of the needle body 3 of the knitting needle 1. 21), and a slider control cam portion 31 that acts on the butt of the slider 5.

The presser unit 13 is installed corresponding to the butt of a select jack selected from three positions, A, H, and B, by a needle mechanism (not shown in the drawing) installed below the presser unit 13. A fixed welt presser (15) is installed at the B position, a chin presser (17) is installed at the H position, and a pair of left and right slider switching presses (19) are installed at the A position. The chin presser 17 and the slider change presser 19 can be controlled to appear and disappear by electromagnets, and can be switched to the operating or non-acting position. As shown in Fig. 1-C of Japanese Patent No. 2917146, the presser presses the butt of the select jack accommodated in the needle groove and sinks it into the needle groove. Therefore, the butts of the needle body 3 and the slider 5 accommodated below the select jack also sink into the needle groove and are not affected by the cam. Also, as described above, the slider switching presser 19 of the present embodiment acts on the butt of the select jack, but, for example, as in Japanese Patent No. 3292836, the slider has two butts (first and second) back and forth. In the case where 2 butts are provided, a slider switching presser may be applied to the first butt (auxiliary butt) on the front side to cause the second butt to sink.

The needle body control cam unit 21 is installed above the presser unit 13. A needle raising cam (23) and a bridge cam (25) are installed in the center, and a stitch cam (27) is installed on the left and right between them. The needle raising cam 23 acts as a rising cam that acts on the butt of the needle body 3 to raise it to the knit position. The bridge cam 25 lowers the butt of the needle body 3 and guides it to the subsequent stitch cam 27. The slider control cam unit 31 is installed above the needle body control cam unit 21. A slider lasing cam (33) is provided in the center, and slider side lasing cams (35) are provided on the left and right. The slider side raising cam 35 is installed in phase with the slider switching presser 19 in the moving direction of the carriage. Additionally, the slider switching presser 19 has an operating position only on the trailing side of the carriage moving direction, and a non-acting position on the leading side.

Since the butt of the select jack at position B is pressed by the welt presser (15) while the carriage moves, the knitting needle (1) at this position is affected by the action of the needle raising cam (23) and the slider raising cam (33). Because it does not receive the knitting needle, the knitting needle does not form a stitch (miss).

In the H position, when the chin presser 17 is in the operating position, each butt of the needle body 3 and the slider 5 is sunk by the chin presser 17, so that the needle raising cam 23 By breaking the connection with the cam in front of the top, each butt passes through the root (42) without being affected by the slider raising cam (33). When the chin presser 17 is in the inactive position, the butts of the needle body 3 and the slider 5 rise along the inclined surfaces of the needle raising cam 23 and the slider raising cam 33, respectively. Afterwards, the butt of the slider 5 rises under the action of the slider side raising cam 35 and passes the route 41 of the broken line in the drawing. The organization at this time will be described later.

In the A position, when the slider switching presser 19 is in the inactive position, the butt passes through the same route as when the chin presser 17 is in the inactive position in the above-described H position. When the slider switching presser (19) on the trailing side at position A is in the operating position, the butts of the needle body (3) and the slider (5) adhere to the inclined surfaces of the needle raising cam (23) and the slider raising cam (33), respectively. Since it receives the pressurizing action of the slider switching presser 19 after rising, the butt of the slider 5 goes straight without engaging the slider side raising cam 35, and falls under the action of the slider guide cam 39. . As a result, the butts of the needle body 3 and the slider 5 pass through the root 40 indicated by a solid line (knit).

<Loop Presser>

As described in Japanese Patent No. 4102430, the roof presser 9 is provided on an auxiliary bed (not shown in the drawing) above the needle bed, and the roof presser control cam (not shown in the drawing) is mounted on the carriage. (not shown) advances and retreats with respect to the needle bed gap, and also descends from above the needle bed gap to push down the knitting yarn. Although it is possible to install the loop presser 9 for each plurality of knitting needles, it is preferable to install the loop presser 9 in correspondence with each knitting needle, so that the pattern portion of the punch lace knitted fabric is formed with random knitting needles. It becomes possible to do so. In other words, it has the advantage of being able to eliminate pattern restrictions.

<Sudden sand tunnel>

A rapid sand dune is shown at the top of Figure 1. The leading side in the moving direction of the carriage is the lace yarn feeding port 45, and the trailing side is the pattern using yarn feeding port 47. The lace yarn feeder 45 is placed ahead of the pattern yarn feeder 47 so that the lace yarn 49 extending to the knitting needle 1 is positioned lower than the pattern yarn 51, and the lace yarn feeder 45 is also placed in front of the pattern yarn feeder 47. The height is lowered. If a height difference can be obtained between the lace yarn 49 and the pattern yarn 51, instead of this configuration, for example, by advancing more lace yarn feeders 45, the height of each yarn feeder may be the same. . Since the lace yarn 49 is placed below the pattern yarn 51, the lace yarn is sometimes called the lower yarn and the pattern yarn is sometimes called the upper yarn. Additionally, if a transparent nylon-based lace yarn 49 is used, a visual effect such as a clear pattern yarn portion can be obtained, but the lace yarn 49 is not limited to this, and other types of yarn may be used.

<Punch race organization>

Below, a method of knitting a punch lace knit fabric performed using a flat knitting machine of this configuration will be described. In this embodiment, the case where the knitting needle 1 at position A passes through the root 40 and the knitting needle 1 at position H passes through the root 41 will be described as an example. In the course of knitting a punch lace knitted fabric, the knitting needle 1 is selected at the H position to knit the base 55 of the knitted fabric with the lace yarn 49, and the knitting needle 1 is used to knit the pattern portion 57. Select at location A. In this embodiment, the knitting needle selected at position A is called a pattern needle (hereinafter referred to as knitting needle (P)), and the knitting needle selected at position H is called a base knitting needle (hereinafter referred to as knitting needle (B)). In the cam system 10, the slider changeover presser 19 and chin presser 17 on the leading side are set to the non-acting position, and the slider changeover presser 19 on the trailing side is set to the working position.

First, when the carriage moves to the left along with each yarn feeding port, the needle body 3 and slider 5 of the knitting needle B and P reach the X position through the root 40 together. Figure 2(a) shows the state of the needle bed gap at this time. The needle body 3 and the slider 5 are in a state in which the hook 7 is opened with a distance between the tip of the hook 7 and the slider 5 due to the difference in the amount of advance by the cam. The lace yarn 49 is within the advance and retreat trajectory of the hook 7, and the pattern yarn 51 is above the advance and retreat trajectory of the hook 7. The loop presser 9 advances to a position higher than the pattern yarn 51.

After the X position, each slider 5 of the knitting needle B and P takes a separate route. In position A, since the slider switching presser 19 is set to the action position, the slider 5 of the knitting needle P is not affected by the slider side raising cam 35 and moves to the root 40 to form a knit loop. ) passes through. Meanwhile, since there is no presser at the H position, the slider 5 of the knitting needle B rises to the Y position through the root 41 by the action of the slider side raising cam 35. Figure 2(b) shows the state of the needle bed gap at this time, and the tip of the slider 5 of the knitting needle B enters between the lace yarn 49 and the pattern yarn 51. At this time, the loop presser 9 is lowered to a position where it contacts the pattern yarn 51. Figure 2(c) shows the state of the needle bed gap of the knitting needle P at position A, and is almost in the same state as Figure 2(a).

In the Z position, the slider 5 of the knitting needle B is at approximately the same height as the Y position, but since the needle body 3 descends along the lower surface of the bridge cam 25, the hook 7 moves toward the slider ( 5) Close the hook by contacting the tip. Figure 2(d) shows the state of the needle bed gap of the knitting needle B at this time. The lace yarn 49 is supported within the hook 7, and the loop presser 9 further descends to push down the pattern yarn 51, but the hook 7 of the knitting needle B is held by the slider 5. Because it is already closed, the hook 7 does not bite the pattern yarn 51. For this reason, the pattern yarn 51 is omitted in Fig. 2(d). Figure 2(e) shows the state of the needle bed gap of the knitting needle P at the Z position. The slider 5 remains in the state shown in Fig. 2(c), the needle body 3 descends along the lower surface of the bridge cam 25, and the loop presser 9 further descends, thereby forming the pattern yarn ( 51) is pushed down to within the advance and retreat path of the hook 7 of the knitting needle P.

Afterwards, the knitting needle P at position A draws in both the lace yarn 49 and the pattern yarn 51 to form a knit loop. Meanwhile, the knitting needle (B) at the H position feeds only the lace yarn (49) into the hook (7), and the pattern yarn (51) is outside the closed hook (7), so the knit loop of only the lace yarn (49) is formed. is formed, and the pattern yarn 51 becomes a miss. In the punch lace knitted fabric knitted in this way, the base 55 of the knitted fabric 53 is formed by the lace yarn 49, and the pattern yarn 51 is formed only at the location where the pattern portion 57 is formed. A knit loop is formed in a state in which it is aligned with the lace yarn 49, and places other than the pattern portion 57 are in a state where loops are not formed and are extended horizontally. By controlling the advance and retreat of the knitting needles (1) within the single cam system (10) in this way, the course knitting of the punch lace knitted fabric can be completed, and the base (55) and the pattern portion (57) are combined continuously in the course direction. Thus, even when forming a plurality, they can be knitted efficiently. Also, in the wale direction, if the base 55 and the pattern portion 57 are arranged in combination, various pattern shapes can be formed on the knitted fabric 53.

In addition, in the above embodiment, in the carriage provided with the cam system 10, the advance and retreat of the needle body 3 and the slider 5 of the knitting needle 1 is controlled by the slider switching presser 19 and the slider side raising cam 35. ), but any other configuration may be used as long as it can provide the knitting needles 1 with the movement necessary for knitting a punch lace knitted fabric. For example, if a drive mechanism is installed on the knitting needle 1 itself to control the needle body 3 and the slider 5, it is of course possible to use a flat knitting machine without a carriage. In addition, not only the type in which each yarn feeding port 45 and 47 moves in conjunction with the carriage, but also the type in which the yarn feeding port itself moves independently of the carriage by providing an independent drive source may be used. By using the yarn feed opening on the leading side as the lower side yarn and the yarn feeding opening on the trailing side as the upper yarn and changing their relationship, it is also possible to knit a knitted fabric in which the relationship between the lace yarns and the pattern yarns in the punch lace knitted fabric is changed.
