Wire wrapped screen is a sieve made from looped wires formed into a deep wedge-shaped section. Individual wedge wires are built into ” Panels ” by threading cross rods of suitable diameter through the loops. The whole is then clamped and made secure usually by riveting or putting ring nuts over the cross rod ends or by welding.
The wedge wire screens can be supplied in various shapes and forms as per the requirements such as FLAT PANELS, CURVED SIEVE BENDS, CONICAL BASKETS, CYLINDERS, TROUGHS DISKS either in one one piece or in segments. For curved, cylindrical and conical screens in most cases the cross rods lie along the circumference and profile wires run parallel to the axis. Occasionally this arrangement is reversed.
ADVANTAGES : Wedge Wire Screens provide a unique combination of the most important features required for maximum screening efficiency.

Wedge wire general data on apertures and sections :
A. Free Clearance
The wedge-shaped sections of the wire from aperatures that become progressively wider in a downward direction, thus ensuring rapid flow of material through them. Clogged and blinded aperatures are reduced to an absolute minium.
Wedge wire screens are manufactured by resistance welding V-shaped wire on support rods. Our wedge wire screen begins with the highest quality raw wire then is made into screen that is cut, shaped, fabricated and cleaned.
Wedge wire can be ordered as raw screen material or fabricated to a finished product to suite your application requirements. The pin point control over the specifications of the slot is what allows Federal Screen to provide its customers with highly accurate flow distribution and effective media, debris and sediment filtration. Support Rods running perpendicular to the wrap wire strengthen and maintain the proper design configuration of the screen allowing it to handle intense pressure demands.
