Abstract

Radial brush polishing machines timber of the type generally cylindrical, which have a central core around which alternate adjacent layers of the active materials are arranged longitudinally, axially, the core is coupled to a shaft motor which transmits a rotary movement, characterized in that its structure comprises: - layers of fibers gives (1) of equal length, arranged along the side surface of the core (2), in the direction of the generatrices of the cylindrical, in axial planes, so that the fibers are oriented radially, being subject each plane beam bast it through its center and folded back on itself, so that always appear in two brush fiber layers adjoining it, being the same central holding element of the fibers, the attachment means to the core; - layers (3) of the flexible polishing material, preferably sheets of leather, also arranged in axial planes relative to the core (2), of equal length and width than the layers (1) of pita fiber and alternating in assembly with every two of them, each sheet being provided with parallel transverse cuts (4), from its outer edge to the vicinity of its insertion into the core, to improve its flexibility and adaptability to the wooden piece to be polished.
