Patent
CA 2443058
A screen material having a flexible member is disclosed. The screen material (10) includes closely spaced filter wires (14) supported by a plurality of support members (12). A stranded cable (12) is used as the support member to provide flexibility to the screen material. The filter wires are welded to the members and define filter gaps (24) between adjacent filter wires to allow liquid and small particles to pass through, while retaining particles too large to fit through the filter gaps.
L'invention concerne un matériau de filtre présentant un élément flexible. Le matériau de filtre (10) comprend des fils filtrants (14) serrés portés par une pluralité d'éléments de support (12). Un câble toronné (12) est utilisé comme élément de support pour conférer une flexibilité au matériau du filtre. Les fils filtrants sont soudés aux éléments et définissent des espaces filtrants (24) entre les fils filtrants adjacents pour permettre le passage d'un liquide et de petites particules, tout en retenant les particules trop grosses pour passer entre les espaces filtrants.
