Abstract
A method for the manufacture of brushes with a plastic bristle carrier and a bristle configuration of individual or bundlewise-combined plastic bristles is proposed, in that the fastening-side ends of the bristles or bundles are melted to a thickening, thickenings of adjacent bristles or bundles are interconnected by after shaping and displacement of the plastics material and the connections are subsequently embedded in the plastics material of the bristle carrier. The thickenings are shaped by means of a mold to a clearly defined support structure of webs connecting adjacent thickenings and subsequently the support structure and the bristles projecting over the same are embedded by a short length in the plastics material of the bristle carrier. An apparatus for performing such a method and a brush manufactured by such a method are also proposed.
