Abstract:
1. An integral screen for use in a vibrating machine for separating solids from liquid material, comprising a support structure comprising a rectangular support frame defining a first rectangular opening having a width shorter in dimension than a length, and woven wire cloth of orthogonal warp and weft wires, the first rectangular opening in the support structure including a plurality of similarly dimensioned, similarly orientated and regularly arranged smaller rectangular openings or windows, formed by a lattice of struts criss-crossing the first opening, wherein the cloth is bonded to the support structure, being bonded to the lattice struts as well as the boundary of the first opening, with the cloth extending in a tensioned state across the first opening, the cloth has rectangular openings in the weave, having a greater number of warp wires per unit length than there are weft wires per unit length, and the orientation of the cloth is such that the warp wires extend across the width (i.e. shorter dimension) of the first rectangular opening and the weft wires extend across the length (i.e. longer dimension) of the first rectangular opening, with the warp wires also being parallel to the width dimension (i.e. the shorter sides) of the smaller rectangular openings.
