ABSTRACT:
A method and an apparatus for the manufacture of brushes, and brushes manufactured according to such method. A bristle carrier of a elastic material is provided with at least one substantially cylindrically elongated recess. An elongated bristle bundle is inserted into the elongated recess. The bristle bundle has a thickened portion at its insertion end with a transverse cross-section larger than the narrowest transverse cross-section of the recess. The longitudinal axis of the bristle bundle is aligned with the longitudinal axis of the recess, and a force is applied longitudinally on the thickened portion to cause a wall of the recess to elastically spring out so as to permit passage of the thickened portion. After passage of the thickened portion, the wall springs back until engagement of the wall on the bristle bundle occurs to secure the bristle bundle in the recess.
