Abstract
A method and apparatus for the manufacture of bristle products, such as paintbrushes, brushes, brooms and the like, which comprise a bristle carrier and bristle bundles fixed thereto. The bristles are drawn from a continuous strand on a storage reel and pass through a mould, so that the strand is given a random cross-sectional shape. Downstream of the mould, the reshaped continuous strands are fixed to a bristle carrier and then bristles are cut to the desired length, so that the bristle bundles can be given different shapes and the bristle material can be continuously processed from the reel. The cross-sectional shape of the individual bristle bundles can be adapted to the particular intended use.
Claims7
A method for manufacturing bristle products including a bristle carrier and bristle bundles fixed thereto, the method comprising the steps of drawing plastic bristles combined into a continuous strand from a storage reel, delivering the continuous strand to the bristle carrier, fixing an end of the continuous strand to the bristle carrier, and cutting the continuous strand to a predetermined length, wherein the step of drawing includes reshaping the continuous strand to a cross-section differing from an original cross-sectional shape during the step of delivery of the continuous strand to the bristle carrier by applying a pressure laterally acting on an entire circumference of the continuous strand and, wherein the step of fixing the continuous strand is effected after reaching the desired reshaped cross-sectional shape.
