ABSTRACT:
A sieve screen utilizes a frame to support a plurality of profiled screen wires. These screen wires are arranged on the frame in a symmetrical manner about a center line which is transverse or normal to the direction of flow of material to be separated. The sieve screen can be inverted and rotated to extend its life after the profile screen wires initially situated above the transverse central line have lost their separatory effectiveness.
