Abstract
Process and apparatus for the production of bristle products from plastic. The products comprise a bristle carrier and bristles whose utilization-side ends are substantially unformly rounded and located in a contour differing from that of the bristle side surface of the bristle carrier. The opposite ends of the bristles are fastened to the bristle side surface of the bristle carrier. In a particularly preferred embodiment, the process comprises the steps of: clamping the bristles while their utilization-side ends are in a flat plane; substantially uniformly rounding the utilization-side ends of the bristles while they are clamped in the flat plane; loosening the clamp restraining the bristles and thereafter axially displacing the utilization-side ends of the bristles relative to one another to produce the desired contour; and fastening the opposite ends of the bristles to the bristle carrier.
