Abstract (en)
[origin: EP3011863A1] PROBLEM TO BE SOLVED To provide a method for manufacturing a brush efficiently and without skill in which brush bristles are extending radially to form a plurality of spirals around core wires. SOLVING MEANS A plurality of bristle and core wire combination bodies 7 each comprising a bristle 6 of resilient wire formed into the shape of coil and a core wire 2 of metal passed through the loops of the bristle are formed. The same number of other core wires 3 of metal as the combination bodies 7 are prepared. A core wire assembly 8 is formed by approaching the core wires 2 of said combination bodies 7 and the other core wires 3, and placing in the direction of rotation of twisting alternately. A twisted wire body 10 is formed by twisting the core wire assembly 8 continuously in the longitudinal direction, in which a large number of loops 9 of the bristles are arranged in a spiral shape in the longitudinal direction along the twist of the core wires 2, 3. A plurality of rows of spiral brush bristles are formed by cutting the loops 9 of the bristles of the twisted wire body 10.
