Description

Process for the manufacture of wire mesh In the manufacture of Wire meshes, especially those with a larger mesh size, encounter the problem on that these tissues turn out to be slightly wavy and the cords of the axils warp, d. H. no longer remain in a vertical position to the warp thread. Such wavy ones but warped or warped fabrics are used for many special purposes, especially for manufacturing of cell wire mesh, unsuitable. The error mentioned usually occurs when the fabric is worked from warp wire and longer meter lengths of this have been instigated at once. The tension of the warp threads drawn up is not always the same, and the diameter of the slip roller for the individual wire layers also uneven due to the uneven position of the warp threads. This creates in the warp threads when weaving stronger and weaker tensioned areas or larger ones and smaller lengths, which are subsequently in the form of Make waves or bumps noticeable.

Attempts have already been made to compensate for these tension inequalities by that the fabric is processed directly from bobbins instead of the slip roller. but Here, too, the disadvantage described cannot be completely avoided, since the warp bobbins cannot be braked evenly due to their changing weight. It is Furthermore, as in the case of fabric weaving, the individual warp threads have been tried to load with weights in order to achieve the desired even tension. But here, too, technical difficulties arise because these weights, especially in the case of strong warp wires, they have to be quite large in order to achieve the desired result achieve.

It has now been found that one can easily get a practical Sufficient uniform tension of the warp wires can be achieved by in certain distances from each other, e.g. B. all i o m, a thicker, more elastic one Insert as weft threads. For example, you can have two or more round rubber pieces Insert a diameter of 10 to 15 mm and then continue weaving as usual, until a renewed insert of such a rubber rod or rubber hose to the Tension equalization proves necessary. The rubber sticks will be made off again later pulled out of the tissue. The success of the above measure is based on the fact that the warp wires Lie around the rubber shot and, depending on your tension, feel less or stronger Press into the rubber, so that, to a certain extent, all the warp wires that are too long become a bulge and thereby obtain the necessary shortening.

The number of such rubber shots depends on the size of the rubber to be compensated Difference in length of warp wires and flexibility, d. h, softness, of the pickled Shot.

Of course, this can compensate for the tension in the warp wires not only with ordinary wire mesh made of any material, but also with Wire meshes, the weft of which consists of textile threads, are made.

The type of use of the elastic weft material is determined by the enclosed Drawings explained.

Fig. I shows a plan view of the wire mesh located in the loom. The warp wires run in the direction A-B, and the fabric contains as elastic Weft material the round rubber pieces a.

Figures 2 and 3 illustrate the deformation of the elastic weft material in the tissue, namely Fig.2 shows a section in the direction A-B of Fig. i and Fig. 3 is a section in the direction C-D, i.e. H. so a cut through one of the Round rubber pieces serving as elastic weft material.

Claims (1)

PATENT CLAIM: Process for the production of wire mesh, thereby characterized in that from time to time during the weaving process in diameter elastic Weft material, which by its ability to change shape the differences the warp wire tension compensates, registered and after completion of a piece of fabric is removed again.
