The combining of two or more non-identical wire cloth (wire mesh) screens into one set of reinforced hooks to form one screen panel. Typically the finer mesh screen is placed above the larger mesh or support screen.
Wire cloth in which deep crimps are provided in the wires at points of wire intersections to lock wires securely in place. Typically used for heavy-duty screening. Also referred to as "arch crimp", "lock crimp" and "press-lock".
The edge or border of wire cloth finished off so as to prevent unraveling.
Selvage types include looped, folded, cut and tucked, welded, plastic bonded or bent back picket.
Wire cloth (wire mesh) used for shielding radio frequency equipment and rooms. Typically provided in pure copper or brass material.
The wires running the short way of, or across the cloth as woven. Also referred to as "shute", "fill" or "weft" wires.
Metric openings, in a fixed ratio, assigned by the U.S. Bureau of Standards, based upon the number 18 sieve having an opening on one millimeter (0.039370").
The relation of consecutive numbered sieves is as one to the fourth root of two (or for every fourth sieve ratio is as one to two). Sieve numbers are arbitrary numbers and have no direct relationship to the number of meshes per inch.
The actual clear opening or space between the inside edges of two parallel wires.
Square mesh wire cloth which is designated by the width of the open space between the inside edges of two parallel wires.
Wire cloth with the mesh count and wire diameter the same in both directions.
A fabricated assembly of woven wire cloth (wire mesh) designed for the removal of foreign particles from a stream of liquid or gas.
A plain weave off-count mesh cloth with a high percentage of open area.
Fabricated circular frames available in stainless steel, brass or plastic fitted with wire mesh woven of brass, phosphor-bronze or stainless steel, having extremely accurate openings. Sieves are produced according to various standards, in the U.S. typically per ASTM E-11-70.
Testing sieves are used for grading, sizing and testing by research and technical institutions, industrial laboratories and mining engineers.
Wire cloth (wire mesh) woven of wire that has been coated with tin before the weaving process. Tinned cloth is generally available in "mill grade" wire diameters.
Woven wire cloth in which each weft wire passes successively over two and under two warp wires and each warp wire passes successively over and under two weft wires.
Twill Dutch Weave
Each warp wire and each weft wire passes over and under the next to adjacent complementary wires, as in a normal "twill weave", except the warp wires are larger in diameter than the weft wires. This allows a greater mesh count in the weft direction.
This weave pattern enables the weft wires to be woven more densely, and much smaller aperture sizes can be achieved.
The wires running lengthways during weaving are referred to as WARP wires.
The wires that run across the width of the cloth are referred to as WEFT or shoot wires.
A solid wrought product that is long in relation to its cross section, which is square or rectangular with sharp or rounded corners or edges, or is round, a regular hexagon or a regular octagon, and whose diameter or greatest perpendicular distance between parallel faces (except for flattened wire) is less than 0.375 inch.
A general term for material woven from metallic wires.
The diameter of wire before weaving.
