Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for adjusting the position of a jacquard machine on the basis of the weft inserting side when changing the weaving width by changing the type of a fluid jet loom.

[0002]

2. Description of the Related Art As a conventional fluid jet loom, for example, there is a locomotive equipped with a jacquard machine as disclosed in JP-A-1-280046.

As shown in FIG. 7, a main body 2 of a jacquard machine for vertically moving a thread 1 is fixedly attached to the right and left central portions of a jacquard frame 3, a main weft insertion nozzle 4 and a weft end catching device. 5 is provided so as to be movable with respect to the loom 6 in the weft insertion direction (left-right direction). Then, when changing the weaving width of the woven cloth, the position of the jacquard machine body 2 is not moved, and the lead 7 is replaced with one having a large dimension L1 or a small dimension L2 corresponding to the weaving width.
In this replacement of the lead 7, the woven pattern on the jacquard machine body 2 is symmetrical, and the lead is placed on the weft insertion side as a standard like a general fluid jet loom without a jacquard machine. Since the lead 7 cannot be arranged, the lead 7 is arranged such that the center position of the lead 7 in the left-right direction is the center position of the jacquard machine body 2 in the left-right direction, and the weft insertion main nozzle 4 and the weft end catching device 5 are arranged. Dimension L in the reverse weft insertion direction indicated by arrow X or in the weft insertion direction indicated by arrow Y
By moving by 3, L4, the positions of the weft insertion main nozzle 4 and the weft end catching device 5 with respect to the lead 7 are adjusted.

[0004]

When the position of the weft-insertion main nozzle 4 is changed as in the conventional example described above, the distance between the weft-insertion main nozzle 4 and the weft measuring and storing device (not shown) changes. The ballooning when the weft is unwound from the drum of the weft measuring and storing device changes, and the unwinding resistance of the weft changes. Therefore, it is necessary to perform troublesome work such as shifting the position of the weft measuring and storing device and additionally installing a yarn guide.

Therefore, when changing the weaving width, the jacquard machine body 2 is moved with the weft inserting side as a reference,
Although it is conceivable to keep the position of the weft inserting main nozzle 4 fixed, the base of the jacquard machine which elastically supports the thread 1 is lifted to lower the tension of the thread 1 in the lower part of the loom 6. Moves while relaxing, and thread 1
A guide plate (not shown) that guides is also moved, and the positions of these guide plates and the base must be adjusted accurately, which requires a great deal of labor and time.

Therefore, according to the present invention, when the weaving width is changed, the work of moving the jacquard machine body, the guide plate and the base with the weft insertion side as a reference can be easily performed while the position of the weft insertion main nozzle is fixed. It is an issue.

[0007]

SUMMARY OF THE INVENTION According to the present invention, a jacquard machine body for vertically moving a thread, a guide plate for guiding the thread,
In a fluid jet loom including a jacquard machine composed of a base elastically supporting threading, the jacquard machine body, a guide plate and a base are provided so as to be movable in the weft inserting direction with respect to the loom, and these jacquard machines are provided. An interlocking mechanism is provided on the machine, guide plate and base.

[0008]

In order to change the weaving width, the number of threaded yarns is increased or decreased to the number required for the changed weaving width while the interlocking mechanism is operated. Thus, the jacquard machine body, the guide plate, and the base are simultaneously and at the same distance interlocked with the weft insertion side or the reverse weft insertion side, and the positions are accurately adjusted with the weft insertion side as a reference.
