Abstract (en)
[origin: US4944561A] A process for producing brush heads is disclosed which includes providing a bundle of brush material, which is separated into a plurality of bunches of brush material to provide respective brush heads. The plurality of bunches of brush material are inserted into apertures in an apertured plate, with support needles engaged in the respective bundles in the apertured plate. The number, length, shape and thickness of the needles are dependent on the nature, amount, length and shape of the brush material. The apertured plate with the bunches of brush material in the apertures thereof is then fitted to a shaping unit, with the brush material being slid into shaping sockets in the shaping unit, the tips of the bunches providing the respective brush heads assuming the configuration imparted thereto by the blind ends of the shaping sockets. After withdrawal of the apertured plate, a further apertured plate having apertures therein of the desired diameter for the brush heads is pushed over exposed ends of the bunches of the brush heads. Then the ends of the bunches of brush material are fixed by means of an adhesive, after which the second apertured plate is removed from the apparatus.
