Description

DETAILED DESCRIPTION OF THE INVENTION In Kasuri textiles, the Kasuri pattern must be accurately expressed as set.

To do this, the first condition is to warp the kasuri warp threads to the correct condition and run them on the loom.However, even if this condition is met, if the kasuri warp threads f's shift during weaving, the kasuri warp f's will not be accurate. It becomes impossible to express the pattern.

The present invention is a new method in which the Kasuri warp threads do not slide.

This provides a weaving method for new kasuri fabrics, in which the kasuri warp threads are always held horizontally without being given any shedding movement among the warp groups in which the ground warp threads and the kasuri warp threads are warped and arranged according to the desired texture. All or part of the warp threads are pulled down to the lower blade against the horizontal threads of the suspended kasuri warp threads and the remaining ground warp threads, and the weft threads are inserted into the opening between the stopped horizontal threads and the ground warp threads that have been pulled down. Next, the ground warp that has been pulled down is pulled up to the upper blade against the stopped horizontal thread, and the weft is inserted into the opening between the stopped horizontal thread and the ground warp that has been pulled up. When inserting the weft and repeating the weft inserting operation, the rod mechanism is provided so that it can be raised and lowered freely from the lower position of the ground warp that has been pulled down to the lower blade to the lower position of the horizontal yarn that is stopped. The present invention is characterized in that it is possible to weave a Kasuri fabric with a desired texture by allowing the shuttle to fly in the upper position and the shuttle to fly in the upper position.

It goes without saying that this method can be applied to both power looms and hand looms, but the method will be specifically explained below by illustrating an example of its implementation in a hand loom.

FIG. 1 is an explanatory diagram showing the open state of the conventional warp group a.

In this conventional method, in the case of a very simple plain weave as shown in the weave diagram in FIG. 2, the ground warp 1 and the kat warp 2 are made to open vertically alternately by means of a sheath 3.

The code 4 is the rod structure (upper zori), 5 is the reed, and 6 is the kasuri fabric.

Reference numeral 7 indicates a winding pressure, and 8 indicates a winding bobbin of warp yarn group a.

This conventional method involves shearing movement of the upper and lower shedding of the kat warp threads 2bs, which results in shearing.

FIG. 3 is an explanatory diagram showing the opening state of the present invention, and the weaving progresses while the Kasuri warp threads 2 are initially stretched (normally stretched horizontally), and are not opened vertically.

In the case of the organization chart shown in Figure 2, only the ground warp 1 is passed through the sheath 3, and first the sheath 3 is pulled down to the lower blade to open the lower blade against the horizontal Kasuri warp 2.

This operation is performed by stepping on the pedal 9.

When the pedal 9 is pressed, the wire 11 is suspended from the pulley 10.
The right side of the wire 11 moves to the lower blade, and the left side of the wire 11 moves to the upper blade, so the rod 12 vibrates its tip downwards around the fulcrum 13, so the bracket 3 is pulled by the spring 14 and moves to the lower blade, The ground warp 1 is opened at the lower blade with respect to the kasuri warp 2.

In this downward open state, the shuttle 15 is inserted by flying over the shuttle structure f)S. At this time, the rod structure 4 is located below the ground warp 1 which is opened downward. ing.

Next, when the pedal 9' is depressed, the wire 11 moves to the left bs lower blade, and the rod 12 vibrates in the opposite direction to the position indicated by the dotted line.
is opened upward relative to the kasuri warp threads 2, resulting in the state shown by the dotted line, and the pedal 9 returns to the position shown by the dotted line.

In this upwardly opened state, the shuttle 4 is again sent in the opposite direction to insert the weft yarn 15, but at this time, the rod 4 must be positioned below the ground warp 1, which is opened upward. It becomes impossible to send shuttles.

In other words, unlike the conventional method, there is always a thread with a downward opening for each opening, but when opening upward, there is no thread with a downward opening, so the rod structure is a horizontal thread that is on the lower side with respect to the upward thread. If the shuttle is not raised to the lower side, it will not be possible to fly the shuttle over the lever structure 46i.

A feature of the present invention is that the rod 4 is raised and lowered in relation to this opening, and in this respect, the rod 16 for the rod 16 is provided in the same way as the rod 12 for the rod, and the reed 5 and the rod 4 are attached. When the upper blade of the baratan 11 is connected via the rod 18, when the blade 3 moves to the lower blade and opens downward, the lever 4 also lowers, and when the blade 3 moves upward and opens upward, the lever 4 also lowers. 4 also rises upward, making it possible to fly the shuttle over the rod structure 4.

In the figure, reference numeral 19 is a sliding fulcrum, and 20 is a ballast 1.
1 is a baratin rod that supports it so that it can be raised and lowered, 21 is a spring,
22 is a stopper.

In this way, it becomes possible to weave a kasuri fabric having the structure shown in FIG. 2 without moving the kasuri warp threads 2 up and down under full heat.

In this case, unlike the organization chart shown in Fig. 2, when several ground warps 1 are arranged between the kasuri warps 2, for example, when three are arranged, only two on both sides are allowed to perform the vertical shedding motion. , the ground warp threads 2 in the center are stopped as they are.

In this way, some of the ground warp threads 1 f) S may be subjected to vertical shedding motion.

The above is described for the case of hand looms, but the same principle can be applied to power looms.

In the present invention, only the kasuri warp 2 is not involved in the shedding movement, and progresses in the initially stretched state, so the disadvantage that the kasuri warp S is shifted due to the conventional shedding movement is completely eliminated. This results in a kasuri pattern that is exactly as designed.

The fact that the kasuri does not shift means that no matter how detailed the kasuri is designed, it becomes an excellent weaving method for weaving kasuri fabrics that can accurately express fine kasuri that could not be created conventionally.

The opening operation of the present invention is not much different in practice compared to the conventional opening operation, and can be easily carried out, but in the present invention, the means of moving the position of the rod up and down is different from the conventional method. It would be redundant in comparison.

However, this implementation is not a very difficult problem, and the design of the equipment is simple, so even if the cost is higher than that of the conventional method, it is trivial compared to the fact that excellent Kasuri fabric can be obtained. .
