Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a jacquard machine equipped with a water jet wefting device.

In this type of jacquard machine, the water that is sprayed at high speed during the wefting device is splashed around the surroundings, which transmits the movement of the peripheral equipment, such as the warp needles of the jacquard machine, to the warp threads of the loom. Alternatively, the battens that guide the threads may become wet, significantly shortening their lifespan.

In this case, the problem is that the threads and battens are usually made of abrasion-resistant materials, or are processed to be abrasion-resistant.
It has no durability at all against moisture.

That is, the battens are generally manufactured from a material made by laminating many layers of paper and vulcanizing them with sulfuric acid. Although this material is highly abrasion resistant, it is brittle against moisture, and when used for a long time, the paper structure will swell and eventually become deformed.

The object of the present invention is to improve the structure of a jacquard machine in the case of a wefting device equipped with a water jet so as to avoid the above-mentioned disadvantages of battens.

This problem is achieved according to the invention by providing an auxiliary batten made of moisture-resistant material above the wefting device and below the main batten at a distance from the main batten.

The auxiliary batten installed in the present invention is made of a moisture-resistant material, for example a dense synthetic material such as polyethylene.

The installation interval of this auxiliary batten to the main batten is:
This auxiliary batten is spaced so that the water does not rise through the threads because it is too close to the main batten, and the height of the jacquard machine is taken into account, so that the auxiliary batten is placed at a distance that is at least equal to or greater than the maximum shedding of the loom. Set to interval.

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

FIG. 1 is a schematic diagram of a jacquard machine equipped with a water jet wefting device. In this FIG. 1, the water jet wefting device of the loom 11 operates in the same manner as in a conventional water jet wefting device. That is, water is injected from the nozzle 6 in a water jet stream 12 between the warp yarns 4 and 5, thereby inserting weft yarns (not shown) and weaving the fabric 7.

In conventional jacquard machines of this type, a batten is provided directly above the water jet wefting device, so that this batten is wetted by water droplets sprayed from the water jet wefting device.

In the jacquard machine 1 according to the present invention shown in FIG. 1, an auxiliary batten 3 is provided above the water jet and weft device. This auxiliary batten 3 is provided below the main batten 2 at a distance a (FIG. 2). This interval a is such that the main perforated plate 2 and the auxiliary perforated plate 3 do not interfere with each other's movement when the thread threading 10 moves. The value is selected so that it does not reach the main eye plate 2.

The auxiliary batten 3 is attached at the same position so as to overlap the grain of the main batten 2. That is, due to the arrangement of the auxiliary batten 3, the threading thread 10 enters straight into the eye of the auxiliary batten 3 without being bent from the main batten 1, so that the threading 10 is connected to the auxiliary batten 3 and the thread 10 straightly. No significant friction occurs between the two, and the auxiliary batten 3 does not wear out.

By installing the auxiliary batten 3, the water splashed from the water jet wefting device will be transferred to the auxiliary batten 3.
, and will never reach the main batten 2.

Reference numeral 8 in FIG. 1 is a cutter, and 9
14 is a harness guide. Since these are of a conventional jiacard machine and are known per se, they will not be described in detail here.

Furthermore, in FIG. 2, reference numeral 10 is a thread, and 13 is a heddle. These movements during weaving operations are well known and therefore no further explanation will be given regarding these movements.
