Researches on influence of wood sanding direction on wood gluing

Abstract The wood surface quality is most determined by the way in which it has been processed before and tools used for this purpose. Machining its effect primarily on structural shape of formed after tool–wood contact also roughness obtained a specific process. In cases, surfaces elements are materials or semi-finished products further processes, including gluing painting, sanded with sandpaper various grit sizes belt sanders. This causes structure to be unidirectional. No information available literature influence direction post-processing glued Therefore, was subject research study. Two kinds glues were used, three pressures applied. Contrary what expected, mutual position post sanding structures during operation amount glue connection turned out small significance. an extreme case, difference necessary minimum 15.1% same type different against each other. However, kind being pressure have found significant produce good connection.
