WIPO Patent Application WO/1998/000050
Kind Code:
A1
Abstract:
A method of grinding bristle ends of a brush, in which ends of a plurality of fiber materials planted in a brush base are tapered to be gradually narrowed toward ends, comprises placing a plurality of sets of cylindrical-shaped wire brushes (1, 2), wire brushes of each set being different in direction of rotation, one after another at predetermined locations along a direction of movement of tooth brushes (6) in such a manner that a height, at which fiber materials of the tooth brushes (6) and the wire brushes (1, 2) contact with each other, becomes gradually larger; contacting ends of the fiber materials with the rotating wire brushes (1, 2) to successively move the tooth brushes (6) in a longitudinal direction of the wire brushes (1, 2) while rotating the tooth brushes (6) on the wire brushes (1, 2) in a planar manner and swinging a set of the wire brushes (1, 2) in a direction substantially perpendicular to the direction of movement of the tooth brushes (6) to grind the ends of the fiber materials.
