HAVER & BOECKER Woven Wire Cloth Terminology, Types of Weave and Apertures

Wire Cloth Terminology according to ISO 9044 Aperture width w is the distance between two adjacent warp or weft wires, measured in the projected plane at the mid-positions. Wire diameter d is the diameter of the wire in the woven cloth. (The wire diameter may be altered slightly during the weaving process.) Pitch p is the distance between the middle point of two adjacent wires or the sum of the aperture width w and the wire diameter d. Open screening area, Ao: The percentage of the area of all the apertures in the total screening surface or the ratio of square of the nominal aperture width w...

Testing of Woven Wire Cloth according to ISO 9044 Determination of the wire diameter The wire diameter after weaving may be determined by using one of the following procedures: 1.) by measuring wires which have been loosened from the woven wire cloth (e.g. by using a micrometer screw), 2.) by measuring the wires in the cloth, if there is sufficient space for the measuring instrument. Micrometer screw to determine the wire diameter The tolerance of the wire before weaving can no longer be determined in the woven wire cloth, because of its heavy deformation during weaving. The nominal wire diameter,...
