Calendering:
A
rolling operation which flattens the knuckles of wire cloth giving
it a smoother surface.
Crimp:
Undulations in warp and fill
wires which hold each other in place.
Fill Wire:
Also known as shute wire, wire running across the width of the
cloth.
Filter Cloth:
Cloth used for
flattening or straining (primarily plain and twilled dutch wire
cloth and certain specifications of square mesh and off-count standard
wire cloth).
Flat Top:
Top surface of wires all lie in same plane. Irregular crimped
surface on underside.
Hardware Cloth:
Plain weave square mesh cloth
of relatively light wire galvanized after weaving or welding (usually
between 2 to 8 openings per lineal inch).
Intercrimp:
Wires are crimped in a zigzag fashion with intersections
at every 3rd, 5th, or 7th, etc., crimp or pocket.
Lock Crimp:
Distinct crimp or pocket at wire intersection with straight
connecting sections of wire.
Market Grade:
Applies to
wire cloth specifications most commonly used for general work.
Market grade cloth is made of one size wire for each size closed
mesh.
Mesh:
Number of openings per lineal inch, measured from
center of wire to center of wire.
Micron:
1/1000 millimeter,
0.00003937 inch. The unit of measure for particle retention of
filter media.
Oil Tempered Wire:
High carbon steel wire that
is heat treated to produce good strength and abrasion resistance.
Opening:
Dimension
between parallel adjacent wires.
Plain Weave:
Wires are crimped in a zigzag fashion with
wires intersecting at every available crimp or pocket.
Rectangular Mesh:
Wire cloth
with different warp and fill wire mesh counts which results in
rectangular openings. The most common have a higher warp mesh than
filter mesh. Advantages are increased open area and reduced cost.
Selvage:
The
finished edges of wire cloth running the length of the roll which
are produced by the weaving operation.
Space Screen:
Wire cloth
specified by the opening size rather than by the mesh count.
Square
Mesh:
Mesh with equal spacing of warp and shute to give square openings.
Warp
Wire:
Foundation wires running parallel to the length of the
cloth.
Weaves:
Pattern in which wires are interwoven.
Wire Diameter
or Gauge:
Diameter of wire used in weaving cloth.
