Abstract
A single vane slat design for use in a sieve or chaffer of a harvester combine. The single vane slat has a weld pocket, preferably on its bottom surface, for receiving a wire on a frame. The single vane slat may be formed of a 26 gage material, and may be attached to the wire using two small welds. The weld material is configured to flow into the weld pocket upon being welded, and achieve direct and incidental contact between the wire and the slat. The weld pocket of the slat is configured such that the slat is self-fixturing to the wire, which lends to the ability to weld the slats to the wires while fixed in the frame. This facilitates accommodating a large number of frame types and sizes.
