Abstract: A tufting tool for tufting and fastening clusters of bristles in bristle holes in a contoured surface of or oblique holes in a brush body. The tufting tool has a tool head displaceable along the tufting axis between a receiving and a tufting position. The tool head has two guide jaws which are displaceable relative to each other during displacement of the tool head.

The method comprises the steps of: (a) arranging a number of synthetic thermoplastic fibers so that at least one end of each fiber is positioned in the same plane, to obtain a fiber bundle, (b) compressing the thus obtained fiber bundle to the extent that the compressed fiber bundle takes a desired cross-sectional shape and has a desired bulk density, (c) irradiating the fiber ends in the same plane with energy beams to fusion bond them together, and (d) releasing the compression to obtain a final bundle having a fusion bonded fiber ends. In a case where the synthetic fibers are not thermoplastic, a thermoplastic adhesive is additionally used in the step of irradiation.
