Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a warp knitting method and a warp knitting machine, which is particularly useful for producing decorative narrow knitted lace.

(Prior art) It has been known to produce narrow knitted fabrics using a crochet machine, and the resulting knitted fabrics can be used as shoulder hangers or belts for cameras, etc., sandal laces, and ski poles. It is used for grip bands, women's belts, etc. A conventional crochet machine has seven needle bars to which a large number of crochet hooks are attached and which are driven back and forth in a direction perpendicular to the longitudinal direction.The needle bars are arranged parallel to each other, and a large number of warp guide needles are attached to the needle bars. It has seven guide bars that are driven reciprocatingly in the axial direction and rotatably in the circumferential direction, and the two or two weft threads are guided by the guide pipes and moved in the weft direction. , knitted with warp yarns appropriately arranged within a width approximately equal to the weft direction width of the weft yarns. L It's turning into a sea urchin. However, in these conventional knitted fabrics, since the warp yarns are knitted in a straight line, it is impossible or very difficult to vary the width. for example,
The weft thread is moved in the weft direction by the pipe guy 1-
Even if you can change the width, when knitting a part where the weft is wider than the warp, either hold the weft in a pico-soto braid, or match it to the maximum width of the weft. The warp yarns must be arranged and knitted, and the warp yarns on the side 1 of the weft yarns must be pulled out later.However, in any case, the resulting knitted fabric has straight warp yarns. It's Mari (Jmi 1! 1 shitayo, 2 thread shi 1
Since there is nothing to support it, it easily deforms and is weak in strength.

On the other hand, when a narrow width 1il 111 is used for the above-mentioned purpose, it is often more convenient to have a width that varies depending on the purpose rather than a constant width. For example, in the above-mentioned example, a shoulder belt should be wide at the part that touches the shoulder, and a ski pole hand should be narrow at both ends where it is attached to the ski poles. Furthermore, in the above-mentioned uses and other uses, it is possible to decorate by giving various changes to the width, and it is possible to add fashionable elements. However, this has been very difficult with conventional warp knitting methods and warp knitting machines.

(Object of the Invention) The present invention has been made in view of the above-mentioned circumstances, and includes a warp knitting method and method capable of knitting knitted fabrics with varying widths, particularly narrow knitted fabrics. The purpose is to provide a vertical M4 machine.

(Technical Means of the Invention) The method of the present invention includes a needle bar that is reciprocated in a direction perpendicular to the longitudinal direction of the needle bar, a large number of knitting needles attached to the needle bar, and a needle bar that is arranged parallel to the needle bar. 2 which is reciprocatingly driven in the axial direction and rotationally driven in the circumferential direction.
Using two groups of warp guide needles attached to guide bars, the two groups of warp threads passed through the two groups of warp thread guides 1 are moved in the weft direction of each other. This method is characterized by knitting while changing the distance, and the device of the present invention comprises: a needle bar to which a large number of braids are attached and which is driven back and forth in a direction perpendicular to the longitudinal direction of the needle bar; 1. In a warp knitting machine having a guide bar which is arranged in parallel to the heel bar, a large number of warp guide pipes are attached, and is driven to reciprocate in the axial direction and to rotate in the circumferential direction, The warp knitting machine is characterized in that the guide bars (b) are arranged parallel to each other and are movable independently of each other in the axial direction.

In Figure 3, 47 is a needle bar, and as explained earlier, this needle bar 47 is arranged parallel to the guide bars 11 and 12, and is adapted to reciprocate the knitting needles in the left and right directions in the figure. . That is, the needle bar 47 is provided with a large number of needles 147a..., and the braid 46, such as a hook or latch, fits into the needle groove 47a and is held down by the needle clamp material 47b and the needle presser material 48. , bolt 48
It is fixed by a. The needle bar 47 is attached to an angled holding bracket 49, and the holding bracket 49 is attached to a guide bush 50 fixed to the fuselage 1.
It is fixed by a nut 51a to the tip of a drive rod 51 that is reciprocated in the axial direction. In the figure, 52 is knitting needle 4
A knockover bar guides 6, and 53 is a retaining rail. Further, in FIG. 1, 54 is a take-up roller, and 55 is a motor.

FIG. 7 is a plan view showing the drive shaft system of the weft knitting machine. The driving force of the motor 55 is first transmitted to the drive pulley 56, and the main shaft 57 is rotationally driven. The rotation of the main shaft 57 rotates the cam 26.27 for rotating the guide bar 11.12 in the circumferential direction. 58.58 is the drive rod 51
The main cam drives the knitting needle 46, 59 is an oil foil, and 60 is a winding cam.

At both ends of the main shaft 57, a right side shaft 62 and a left side shaft 63 are driven via bevel gears 61, 61.

64, 64 is 1 which drives the semi-forced feed roller 2 of the horizontal month.
65 is a cam for moving and controlling the weft thread guide bar 9 up and down, 66 is a cam for picot, 6
Although not shown in FIG. 1, 7 and 67 are manual handles provided in front of the side cases la and lb.

The pattern drum 6 is connected to the stent shaft 62 via a hevel gear 68, a shaft 69, and a worm gear 70.

In the weft machine configured as described above, by rotating the motor 55, the knitting needles 46 are moved in the front-rear direction, one guy at a time, one needle at a time.
The tip of the weft guide bar 5 moves vertically and horizontally, and the weft guide bar 9 moves vertically and horizontally to knit a knitted fabric using warp and weft yarns. At this time, the guide needle 15 is attached to two guide bars 11 and 12, and each of the guide bars 11 and 12 can be moved independently of each other in the axial direction by a chain cam 31 and 31. Therefore, the guide needles 15 can be divided into two groups depending on which of the upper and lower guide bars 11, 12 they are attached to, and as a result, the warp threads can be divided into two groups. In Fig. 8, eight warp threads Wl, W2...
is divided into the 13 2nd group A and the 2nd group B, and the width is gradually narrowed while swinging the weft CI in the weft direction, and at the same time, the warp threads are knitted while knitting the warp threads Wl, W2, etc. If group A is moved to the right and warp group B is moved to the left, the width becomes narrower as shown in the figure, and by appropriately combining these movements, a knitted fabric whose width changes can be obtained. I can do it. Of course, various knitted fabrics other than those shown in FIG. 8 can be obtained by changing the number and movement of the weft and warp yarns.

The embodiment described above shows one embodiment of the present invention, and various mechanisms can be added, deleted, or modified to implement the present invention.

(Effects of the Invention) According to the present invention, it is possible to easily knit a knitted fabric with varying widths, and a wide part or a narrow part is provided depending on the use of various bands or belts. be able to. Further, it is possible to obtain a knitted fabric with decorations, and it is possible to add fashionable elements.
