ABSTRACT:
An improved sorting apparatus of the harp screen variety utilizes a plurality of elongated, parallel wire spacing strips positioned along a frame and carried on individual beams which are oriented perpendicular to a multiplicity of tensioned wire lengths extending between wire retaining means at opposed ends of the frame. Each spacing strip has a substantially arcuate, convex upper face with a multiplicity of V-cross section wire receiving guideways which are equally spaced therealong to maintain a predetermined distance of separation between the wire lengths. Each guideway has an arcuate floor which has a convex arch configuration which supports the wire length at the apex of the arch and then drops downwardly to thereby minimize destructive abrasion between wire and guideway floor. The guideway construction tends to reduce wear of the guideway in lateral directions and to utilize normal wear to more firmly seat the wire in the guideway and retain desired spacing between adjacent wires. An improved retaining means is also provided to retain and permit easy tensioning of the wire length.
