Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a reed arrangement for a fluid jet loom.

(Prior Art) It has been found that there are various causes of warp lines occurring in the warp direction of textiles, and various countermeasures have been studied.

However, due to the relatively short history of water jet rooms, there are some aspects in which countermeasures cannot be said to be sufficient. In weaving using a water jet loom, it is unavoidable that the water splashed during weft insertion wets the reed feathers. A shift occurs.

When the reeds in the water jet room are dry, they are arranged at equal intervals. but,
For weft beating, when water is driven together with the weft threads and wets the reed feathers, the reed feathers are formed by a part containing water that has accumulated between the reed feathers and a part that does not contain the accumulated water. The so-called eye-crossing phenomenon occurs in which the spacing between the reed feathers and the reed feathers is not equal.

Once water accumulates between the reed blades, this water will not easily scatter even if it receives an impact from beating the reed, and the phenomenon of blindness caused by spots of the accumulated water will continue for a long time.

Such misalignment of the reeds causes the aforementioned warp stripes and warp lines, especially in the case of textiles that use long fiber yarns with no twists or sag, i.e., filament yarns or crimped yarns, in the warp yarns. Because there is no twist, the thread lacks roundness and is prone to such defects.

It has also been found that the higher the rotation speed of the water jet room, the more warp muscles occur due to misalignment of the reed.

For reed feathers, it is not possible to use special shapes or materials from the viewpoint of reed density, prevention of fuzz due to damage to the threads, and maintenance of sufficient strength to allow reed beating. However, no good solution has been found regarding the generation of transmuscular muscles.

In order to solve this problem, the applicant of the present invention proposed Japanese Patent Application No. 58-173190. However, Tokugan Akira
The method described in No. 58-173190 requires a special reed and requires some ingenuity in the mechanism of the loom.
The problem is that it cannot be done easily.

(Object of the Invention) An object of the present invention is to solve the above-mentioned problems and to propose a reed device for a fluid jet loom that easily prevents warp lines.

(Structure of the Invention) The present invention provides a water conduit having a water supply port that can supply water between any of the reed blades over the width of the reed in the lower part of the reed gripped by the upper and lower reed gripping members. A reed device for a fluid jet loom, characterized in that the water conduit is provided to move integrally with the reed.

The present invention will be explained with reference to the drawings.

1 and 2 are perspective views showing the apparatus of the present invention. In FIG. 1, in FIG. 2, a reed 1 is held by an upper reed gripping member 2 and a lower reed gripping member 3, and below the reed 1 is a conduit 4 with a water supply port 4'. The water conduit 4 is provided so as to move integrally with the reed. In the case of FIG. 1, the headrace 4 is formed by a headrace 5;
is attached by a conduit holder 6 so as to move integrally with the reed.

As in the case of FIG. 2, the water conduit 4 may be integrally formed in the lower reed gripping member.

A preferred example of the lower reed gripping member 3 is one in which the reed is held between a reed holder and a reed clamp.

Further, the water supply port 4' is formed in a slit shape on one side of the water conduit 4 over the width of the reed,
A further example is one in which a plurality of holes are drilled at appropriate intervals.

Further, the water conduit 4 may be provided not only on one side of the reed but also on both sides of the reed, but preferably provided on the front side of the reed.

(Operation of the Invention) According to the device of the present invention, water supplied from a water supply tank (not shown) can be passed through the water conduit 4, and water can be supplied to the lower part of the reed through the water supply port 4'. . This water supply reduces the uneven accumulation of water between the reed blades, thereby reducing the crowding of the reed blades and keeping the reeds at equal intervals, which can reduce warp muscles. It is.

In particular, the device of the present invention is particularly suitable for fluid jet looms that rotate at 500 revolutions per minute or more.
Further, when using a synthetic fiber multifilament with no twist or glue as the type of yarn, the device of the present invention can be used with great effect.
