Wire mesh

WITH SMOOTH WEAVE

This is the most common weave used to make wire mesh. Each wire is bent in a warp or a weft, and this alternates regularly.

WITH TWILLED WEAVE

Twilled weave

Two wires are bent and then offset by one wire (see figure). This weave is chosen primarily when the wire is too thick in relation to the mesh dimensions, or where the fabric is too fine, so that the wire does not hold when bent in the woven weave.

Pointed or alternated twill

This method of bonding is used where possible transverse displacements must be excluded. Due to the frequently occurring differences in the holes, it is mainly used for the manufacture of various inserts and only very rarely in filters or sieves. (see fig.).

FILTERING

Plain weave

The weft wires are so close together that they create “zero meshes”. The warp wires are stronger than the weft wires. Good flowability, given by the same openings, and easy cleaning are the main advantages of these wire mesh.

Twilled weave (light impervious)

The weft wires in twill weave are placed close together. One weft wire is always above and one wire is below the warp wire. Compared to plain weave, there are twice as many wires (see figure).

Armored binding, or inverted belt

Unlike woven belts, most of the wires are located in the warp system. The weft wires are therefore significantly stronger than the warp wires. This special construction is characterized by great stability and guarantees good flowability.

Open filtration weave

This wire mesh is made in the same way as conventional belts. The weft wires are not placed so densely next to each other, but at a certain distance, which increases the flow capacity of the wire mesh. The disadvantage is the less regularity of the holes. Open filter cloth is made:

1. in a smooth weave
2. in a twilled weave

Twilled armour weave

This is a technical cloth where the combination of twill weave and the placement of most wires in the warp allows for use in extremely demanding environments, thanks to its high stability and strength.
