Abstract
A screen material having a flexible member. The screen material includes closely spaced filter wires supported by a plurality of support members. A stranded cable is used as the support members to provide flexibility to the screen material. The filter wires are welded to the members and define filter gaps between adjacent filter wires to allow liquid and small particles to pass through, while retaining particles too large to fit through the filter gaps.
