Abstract

PROBLEM TO BE SOLVED: To provide a water jet loom having a simple structure and excellent in durability without depending on a fluid means and a mechanical means and having a weft end treating function free from fear of loosening of yarn accompanied by advance of reed. SOLUTION: This water jet loom comprises a yarn supplying nozzle of weft 1, a catch code for catching the tip of the weft 1 traveled from the yarn- supplying nozzle, a reed for beating picked weft and a weft end treating tool located on the anti-yarn-supplying side of the catch code. In this water jet loom, the weft end treating tool has the following constitutions: (a) in a pair of weft-holding plates 6 and 7, either one end thereof is brought into contact with either one end thereof and the other ends are fixed to reed body in open state; (b) the open state turns the direction of jet flow yarn supplying yarn nozzle and is located on a traveling line of the weft 1; (c) either one of the weft holding plates 6 and 7 is an elastic material and the contact state of either one end with either one end is opened as jet water from the yarn supplying nozzle flows in through the opening and returned to the original contact state after flowing-out.

Further, it is necessary that both or one of the weft holding plates 6 and 7 is made of an elastic material.
The elastic material is not particularly limited as long as the weft holding plates are released from the contact state by the inflow / outflow action of the jet water and return to the contact state again, that is, the open / close state occurs. Practically, it is desirable to use a material having bending elasticity, such as a thin metal piece such as aluminum or stainless steel, a resin, or a rubber material. Such materials usually have a thickness of 0.1 to
What is necessary is just to make a holding plate of about 0.5 mm, width of 3 to 10 mm and length of about 20 to 40 mm.

FIG. 2 is an enlarged view showing an example of a weft grasping device, in which a weft grasping plate 6 and an attaching member 10 having bolt holes 9 are integrally connected to an attaching member 8 having bolt holes 7.
The weft gripping plate 7 integrally connected to the reed frame 11 is fixed to a mounting plate 12 fixed to a reed frame 11 in a state as shown in the figure.
In this case, if the weft holding plate 6 is made of an elastic material and the same 7 is made of an inelastic material, as shown in FIG.
When the weft is inserted, it opens and closes as indicated by the arrow due to the action of the jet water. As a result, the weft inserted with the jet water in the "open" state is gripped in the subsequent "closed" state.

According to the present invention, the portion of the weft opposite to the yarn supply side during beating is not loosened, and a constant tension can be applied over the entire length of the weft. As a result, in the case of weft-inserting a high-twisted yarn in particular, conventionally, the formation is inevitably different between the woven portion woven on the yarn supply side and the woven portion woven on the non-yarn supply side. The above critical problem is solved with a simple device.
