Title:
BRUSHING MACHINE FOR PRODUCING VINTAGE-STYLE LUMBER, VINTAGE-STYLE LUMBER, AND METHOD FOR PRODUCING VINTAGE-STYLE LUMBER
Document Type and Number:
WIPO Patent Application WO/2019/203174
Kind Code:
A1
Abstract:
[Problem] Conventional vintage-style or antique-style lumber does not have a natural worn look on the painted surface thereof and therefore it is evident that the lumber has been artificially processed. [Solution] The roller brush according to the present invention is configured such that a rotary shaft is rotated at a high speed at an angle that is an arbitrary right angle with respect to a direction in which a piece of lumber subject to surface processing is conveyed by rotary conveyance rollers and that is also a predetermined tilt angle with respect to the horizontal surface of the piece of lumber in the lateral direction of the roller brush, unlike conventional examples in which a rotary shaft is just fixedly arranged in parallel with the grain and the colored surface, which is obtained by coloring the grain, of a piece of lumber. According to this configuration, the way the roller brush such as a metal brush touches the piece of lumber differs between the left and right ends of the piece of lumber, and accordingly the grain and the colored surface obtained by coloring the grain are peeled off with different strength in the left and right sides of the piece of lumber by the tilted roller brush. It is therefore possible to perform uzukuri processing (uneven wooden surface processing) with which lumber having different designs in the lateral direction can be obtained.
