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 join 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 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. An ultraviolet resistant lacquer may be applied to the covering layer for long window life and attractive finish.
Les structures et procédés utilisés pour produire les structures de l'invention permettent l'utilisation à grande échelle et efficace des déchets de blocs pour la fabrication de lamelles (91, 171, 205, 255). Les techniques employées permettent d'atteindre simultanément deux objectifs: en assemblant les déchets de blocs en blocs de longueur utilisable, et en débitant les blocs reconstitués en lamelles (91, 171, 205, 255) de différentes tailles. Le raccord entre blocs s'obtient par pénétration en profondeur d'entures multiples qui lorsque le matériau est découpé en lamelles (91, 171, 205, 255) reste un joint à entures multiples mince. De tels joints ont de plus l'avantage de "rompre" statistiquement les possibles différences de grain pouvant sinon créer un gauchissement, tout en permettant d'obtenir des lamelles (91, 171, 205, 255) de grande longueur par assemblage de déchets courts. On peut appliquer aux lamelles une couche de couverture par enrobage ou insertion sur laquelle on peut appliquer une laque résistant à l'UV, esthétique et prolongeant la vie de la persienne.
