摘要： A method of making rotary driven brushes, particularly road-sweeping brushes, by arranging bunches of bristles (2) so that their one ends (2a) extend into a mould (3) for forming the brush base (1), and applying into the mould (3) around the ends (2a) of the bristles a quick-setting liquid plastics material, generally a micro-cellular elastomeric polymer material such as polyurethane foamed by adding water thereto, and allowing the plastics material to set to secure the brush base to the bristles.

摘要： A process for manufacturing a brush having an integral bristle retention feature. One end of each bristle tuft to be inserted into a molded brush body is fused into a ball-shaped mass. The body is molded around the mass, thereby anchoring the tufts in the body.

摘要： The invention relates to a brush provided with bristles made of an organic thermoplastic synthetic material such as nylon, particularly a tooth-brush. The free ends of the bristles which are sharp and therefore able to damage soft surfaces are made round by a heat treatment. The bristle ends are preferably submitted to a laser beam treatment, the source of laser beams being preferably placed below the bristle ends. Particularly, the brush and the heat source are submitted to a relative movement and the heat treatment takes place in an atmosphere of an inert gas. The invention relates also to a brush, preferably a tooth brush, having a head carrying a plurality of monofilaments made of an organic thermoplastic synthetic material. The monofilaments are tangentially welded to each other in a hole provided in said head, so that a plurality of capillary channels is obtained, said channels being open, on the one hand, on the side where the filaments protrude from the brush head and, on the other hand, on the side of the brush head opposite to the side carrying the protruding monofilaments. Impurities may thus be removed through the open-ended capillary channels, when the brush is cleaned.
