Abstract

(57) [Abstract] [Purpose] An object of the present invention is to provide a stitching width changing device in a jacquard device that does not require replacement of the stitching plate even when weaving fabrics having different warp densities. [Structure] In a jacquard device, an eye plate 2 is composed of left and right eye plate portions 2a, 2a positioned with a hinge portion as a boundary, and side edges of the eye plate portions 2a, 2a move up and down to allow angle adjustment. Even when weaving fabrics having different warps and densities, it is not necessary to replace the eye plates, and it is possible to handle various weaves having different warps and densities by operating the left and right eye plate portions 2a, 2a.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an eyelet threading width changing device in a jacquard device which is used when changing the density in the width direction of a fabric woven by the jacquard device, that is, the so-called density.

[0002]

[Prior art]

 Conventionally, a jacquard opening threading plate is formed with a fixed number of guide holes in a fixed width at a fixed pitch, and the pitch of the guide holes can be changed with one plate. I couldn't. Therefore, when changing the warp density of the woven fabric, the guide plate is replaced with the reed according to the warp density of the woven fabric, and at the same time as the replacement, it is necessary to pass the thread through the inner hole of the eye plate. There was a problem that it was very troublesome.

[0003]

[Problems to be solved by the device]

 The present invention solves such a problem, and an object thereof is to provide a stitching width changing device in a jacquard device that does not require replacement of the stitching plate even when weaving fabrics having different warp densities. is there.

[0004]

[Means for Solving the Problems]

 In order to solve this problem, according to the present invention, in a jacquard device, the eye plate is composed of left and right eye plate portions that are located at the boundaries of the hinge portion, and the side edge portions of the eye plate portion move up and down to adjust the angle. It is composed of.

[0005]

[Action]

 With this configuration, it is not necessary to replace the siding plates even when weaving woven fabrics having different warp densities, and it is possible to cope with weaving of various woven fabrics having different warp densities by operating the left and right eye plate portions.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a thread which can be moved up and down by an elevating device above the jacquard device, 2 is an eye plate having a large number of guide holes 3 for at least the number of the thread 1, and has a flat rectangular shape, A hinge portion is provided at the center of the long side, and the left and right eye plate portions 2a, 2a are inclined with the hinge portion as a boundary. More specifically, the hinge portions of the left and right eye plate portions 2a, 2a form valleys, and the side ends of the left and right eye plate portions 2a, 2a move up and down so that the angle can be adjusted. Although not shown in the drawing, this angle adjustment is performed by operating the steering wheel or the like. Reference numeral 4 is a support frame that supports the eye plate 2, and 5 is a reed through which a large number of warp threads 6 pass. The warp yarns 6 are inserted in the mails 7 connected to the yarn passing yarns 1 projecting downward from the guide holes 3 of the eye plate 2.

In the above structure, when the warp density is changed, the side edges of the eye plate portions 2a, 2a are moved up and down so that the eye plate 2 when viewed from the front is horizontal to V-shaped or V-shaped to horizontal. The angle changes to. That is, when the siding 2 is horizontal, the warp density in the width direction of the fabric is the smallest, and the smaller the angle of V is, the larger the warp density is. By moving the side end portions of the eye plate portions 2a, 2a up and down in this manner, weaving of various woven fabrics having different warp densities can be dealt with.

[0008]

[Effect of device]

 As described above, according to the present invention, even when weaving fabrics having different warp densities, it is not necessary to replace the eye plates, and it is possible to handle various weave fabrics having different warp densities by operating the left and right eye plate portions. it can.
