Deep arch Sieve Screens is manufactured by a V or wedge shaped wire around an internal array of longitudinal support rods. Each intersection point of this wire is fusion welded. The V or wedge shaped profile wire wraps around the support rods over the full length of the screen creating a continuous slot opening
Looped Wedge Wire is made from round wire which is first looped at regularly pitched intervals and then pressed into a deep wedge shaped section. The loops themselves are pressed so as to produce at each side accurately sized spacing shoulders which butt together when the wires are assembled
