CA 2251929

Brushes with a bristle carrier and a bristle facing of individual, vertical plastic bristles are manufactured in that the individual bristles with their fastening-side ends at the front are introduced into in each case one hole of a hole template, whose hole diameter is slightly larger than that of a single bristle and whose hole pattern corresponds to the positioning of the bristles within the bristle facing or part thereof, to such an extent that their fastening-side ends project roughly to the same extent at the opposite side of the hole template, the bristles are subsequently fixed against axial and radial displacement in the hole template, at least on the fastening-side surface of the bristle carrier is prepared a bed of liquid, curable material, the liquid material flows round the bristles with their fastening-side ends immersed in the bed and subsequently the bed is cured.

L'invention concerne des articles de brosserie comportant un support pour les poils et un ensemble de poils constitué de poils individuels en matière plastique. Le procédé de production de ces articles de brosserie consiste à introduire les extrémités côté fixation de chaque poil individuel dans un trou d'un gabarit perforé, dont le diamètre des trous est légèrement supérieur à celui d'un poil individuel et dont le motif de perforation correspond au positionnement des poils dans un ensemble de poils ou une partie de cet ensemble. Les poils sont introduits de sorte que leurs extrémités côté fixation dépassent d'une longueur pratiquement égale du côté opposé du gabarit perforé. Les poils sont ensuite fixés dans le gabarit perforé de façon à empêcher tout déplacement axial et radial. Une couche de matériau liquide durcissable est préparée au moins sur la surface côté fixation du support de poils, et entoure les poils dont les extrémités côté fixation sont plongées dans la couche, puis cette dernière est durcie.
