TYPES OF WEAVES
Plain Weave
The simplest form of weave and the one most commonly used. Each shute wire passes alternately over and under the warp wires at right angles.
Twilled Weave
Used where heavier wires are needed to produce a square opening in a fine mesh. Each shute wire passes alternately over two warp wires and under two warp wires. By staggering the interlacing, a diagonal pattern is produced.
Plain Filter Cloth
Plain Filter Cloth or "Dutch" Weave is identical in structure to plain weave. The differences are that the warp wires are heavier and the lighter shute wires are crimped and tight against the warp wires, resulting in a small triangular opening.
Twilled Filter Cloth
Twilled Filter Cloth or Twilled "Dutch" Weave is the same as plain filter cloth except for the wire sizes and in overlapping the shute. This allows twice the number of wires per inch.
TYPES OF CRIMPS
Conventional Double Crimp
The most popular type. Used where the opening is relatively small in comparason to the wire diameter (3 to 1 or less).
Lock Crimp
Used in coarse specifications to maintain the accuracy of weave throughout screen life where the opening is large with respect to wire diameter (3 to 1 or greateer).
Inter Crimp
Used in coarse weaves of light wire to provide greater stability, tightness of weave and maximum rigidity.
Flat Top
Usually starts at 5/8" opening and larger. Provides longest abrasive resistance life since there are no projections on top to wear. Offers least resistance to flow.
