DE20306670U1 - Wire fabric consists of metallic material and contains warp ends and picks woven together in weave construction - Google Patents

Abstract

The warp ends (11) and picks (12) and/or meshes are fixed in the edge section through a stabilisation layer (13). A cut fabric section (10) is covered over its full area or in the edge sections by the stabilisation layer either on one or both sides. The layer is a film, a plate, a fabric or a similar flat structure and is made of thermoplastics or other non-metallic material.

Description

Wire mesh

The invention relates to a wire mesh which comprises warp and weft threads made of a metallic material and woven together in a weave.

The wire mesh in question is known in many designs.

The warp and weft threads can be made of a wide variety of metallic materials, including stainless steel. The diameter of the warp and weft threads and the spacing that determines the mesh size depend on the intended use.

Many products are made from the wire mesh in question, such as filters, sieves and the like. The type of binding depends on the intended use.

The width of a wire mesh mat produced by a screening machine depends on the width of the weaving machine's frame. Before the products are

are made, cut pieces are made from a wire mesh mat. It is unavoidable that the cut pieces will warp, i.e. the rectangular mesh becomes a mesh that can no longer be defined. This property occurs particularly when the wire mesh is very coarse, and the warping also depends on the material. This can cause the wires to slip over one another.

Furthermore, the threads can come loose at the edges and fall out. In order to eliminate these disadvantages, it is known to clamp the wire mesh in a frame or to connect the crossing threads at certain points using a sintering process. Both methods are extremely complex, since a frame is an additional part and relatively high temperatures are required for stabilization by sintering.

The invention is based on the object of designing a wire mesh of the type described in more detail at the outset in a simple manner in such a way that the wire mesh is prevented from warping, that the wires, depending on the material, slide over one another and that threads are also prevented from coming loose and falling out at the edge areas. The use of a frame or treatment with relatively high temperatures should be dispensed with.

The task is solved by providing the stitches and/or threads in the edge areas with a stabilizing layer on at least one side to fix them.

The stabilizing layer gives the wire mesh its own stability, which means that the wires can no longer slide over each other and that the rectangular shape of the mesh is maintained.

It also prevents threads from falling out in the edge areas.

The stabilization layer forms a bond with the threads running parallel to the cut edges and with the end regions of the threads running transversely to them, thereby achieving the stabilization effect.

If thermal treatment is necessary, this can be carried out at significantly lower temperatures than in the sintering process.

Although it is sufficient if a wire mesh cut has the stabilizing layer in the edge areas, depending on the application it may be useful if a cut is provided with the stabilizing layer over its entire surface.

In some applications it may also be useful if either the edge areas or the entire cut are provided with a stabilizing layer on both sides.

In a further embodiment, it is also provided that the carrier material is flat, for example in the form of a film, a plate, a fabric, a panel or the like. In principle, the stabilization layer can consist of any material. However, non-metallic materials or thermoplastic materials are preferred.

Known joining techniques can be used to connect each stabilizing layer to the wire mesh or wire mesh blank. However, in a preferred embodiment, the connection is made by an adhesive layer, by thermal treatment or the like, depending on the material.

The invention is explained in more detail with reference to the accompanying drawing.

In the blank 10 according to Figure 1, the viewing direction is in the direction of the warp threads 11. The weft threads running transversely thereto are identified by the reference number 12. The type of weave shown there is to be seen as an example, since all types of weave are possible for the wire mesh according to the invention.

In the illustrated embodiment, the blank 10 is provided on one side with a stabilizing layer 13, which can extend either over the edge regions of the blank 10 or over the entire surface of the entire blank 10.

Contrary to the illustration, the blank 10 could also be provided with the stabilizing layers 13 on both sides, either in the edge areas or over the entire surface. This stabilizing layer 13 can be made from a film, a plate, a fabric, a panel or the like and forms a carrier material layer for the warp threads 11 and the weft threads 12, i.e. the blank is applied to this carrier material.

Depending on the material, the connection between the stabilization layer 13 and the cut 10 of the wire mesh can be made by an adhesive layer or by thermal treatment.

In general, the known connection techniques can be used.

The stabilizing layer 13 prevents the stitches formed by the warp threads 11 and the weft threads 12 from shifting or from threads sliding over one another or falling out in the edge areas.

The invention is not limited to the embodiment shown. It is essential that a blank 10 made of a wire mesh is provided with this stabilizing layer at least on one side in the edge areas, whereby this stabilizing layer 13 forms a firm connection with the warp threads 11 and the weft threads 12.
