Abstract

684,093. Shaping bristle-ends. SOC. ELETTROCHIMICA DEL TOCE. April 14, 1949 [April 29, 1948], No. 10176/49. Class 19. A process for pointing and/or flowering the tips of monofilament bristles for brushes is characterised in that the bristles are exposed to the action of the needles of a moving card-wire band, the needles having smooth surfaces and flat ends and substantially constant cross-section over their whole length. The treatment may be applied to bunches of bristles or to the bristles when mounted in the brush. The bristles are given a rotary movement during the treatment and depending on the length of the needles the tips of the bristles may be shaped conical or simply rounded; at the same time the tips may be split, forming the flowering effect. Suitably, the card-wire band may be carried by a cylinder adapted to rotate at a speed corresponding to a peripheral speed of the band of at least 1750 metres/min. The treatment may be applied to natural bristles such as horse-hair and to natural or synthetic plastic filaments e.g. synthetic linear superpolyamide filaments, for use in such brushes as paint and toilet brushes.
