The structures and process for producing the structures of the invention enable extensive and efficient use of block scrap for slat manufacturing. The techniques employed advantageously accomplish two goals simultaneously, enabling scrap, such as block scrap, to be formed into longer effective lengths. Such longer effective lengths can then be cutably formed into slats of various sizes. The joinder of the block scrap is by deeply extending, finite interlock length finger joints which, once the material is cutably formed into slats, remain as relatively shallow (the thickness of the slat) and finite interlock length finger joints. The joints have the added benefit that they statistically “break up” any grain differences which would otherwise create warp, and enable long lengths of slat to be employed from several shorter lengths of scrap. An applied covering layer may be applied by wrapping or insertion.

1. A slat for a window covering device comprising:a slat member having an exterior surface along its length, a first end, having a first end surface, and a second end, having a second end surface, separated by said exterior surface, said slat member having at Least one set of interlock length finger
1. A slat for a window covering device comprising:a slat member having an exterior surface along its length, a first end, having a first end surface, and a second end, having a second end surface, separated by said exterior surface, said slat member having at Least one set of interlock length finger joints, having projections, and extending across its width and located between said first and said second ends of said slat member each said projection having a ratio of a height of extension to a base width of about 2.75:1 to about 3.25:1;a flexible, thin applied covering completely overlying said exterior surface of said slat member which assumes the shape of said exterior surface of said slat member. 2. The slat as recited in claim 1 wherein said slat member first and second ends have an overlying layer of paint. 3. The slat as recited in claim 1 and further comprising a layer of covering material interposed between said layer of applied covering and said exterior surface of said slat. 4. The slat as recited in claim 1 and further comprising a layer of glaze covering said layer of applied covering material to effect a surface finish for said slat. 5. A process for constructing a slat comprising:forming a slat member having an exterior surface along its lengthy a first end, having a first end surface, and a second end, having a second end surface, separated by said exterior surface, and formed by the steps of:in a first board having a first surface opposing a second surface, a first end extending between said first and second surfaces opposite a second end extending between said first and second surfaces, a first side surface extending between said first and second surfaces and between said first and second ends, and a second side surface, oppositely disposed with respect to said first side surface, extending between said first and second surfaces and between said first and second ends, forming at said first end a first alternating series of protrusions and depressions;in a second board having a third surface opposing a fourth surface, a third end extending between said third and fourth surfaces opposite a fourth end extending between said third and fourth surfaces, a third side surface extending between said third and fourth surfaces and between said third and fourth ends, and a fourth side surface, oppositely disposed with respect to said third side surface, extending between said third and fourth surfaces and between said third and fourth ends, forming at said third end a second alternating series of protrusions and depressions complementary to said first alternating series of protrusions and depressions;affixing said third end of said second board and said first end of said first board together with said first and said second alternating series of protrusions and depressions interfitting with one another to form a joined board; andcutting said joined board parallel to at least one of said first and second surfaces to form said slat having at least one of said first andsaid second surfaces as a part of said exterior surface of said slat; andapplying a flexible, thin applied covering completely overlying said exterior surface of said slat member which assumes the shape of said exterior surface of said slat member. 6. The process of forming a slat as recited in claim 5, wherein said applied covering is glued to said slat. 7. The process of forming a slat as recited in claim 5 wherein said applied covering is wrapped onto said exterior surface. 8. The process of forming a slat as recited in claim 5 wherein said applied covering is moved onto said slat by relative movement of said applied covering over said exterior surface of said slat. 9. The process of forming a slat as recited in claim 5 and further comprising the step of applying a layer of glaze to said covering material. 10. The process of forming a slat as recited in claim 5 and further comprising the step of applying a layer of paint to at least one of said first and sec ond end surfaces.
