Abstract

Zur Herstellung von Zahnbürsten wird in einem ersten Herstellungsschritt ein Trägerplättchen (110) mit einem weichelastischen Element (112) oder mehreren solchen Elementen sowie mit Löchern (114) für Faserbündel in einem Zweikomponenten-Spritzgießwerkzeug geformt. In einem zweiten Herstellungsschritt wird das Trägerplättchen (110) mit den weichelastischen Elementen (112) und mit den Löchern (114) für die Faserbündel in ein Beborstungswerkzeug eingebracht, in dem Faserbündel in die Löcher eingeführt und an dem Trägerplättchen befestigt werden. In einem dritten Herstellungsschritt wird das Trägerplättchen (110) mit den weichelastischen Elementen (112) und mit den befestigten Faserbündeln in ein Spritzgießwerkzeug eingebracht, in dem der Bürstenkörper oder ein Teil davon an dem Trägerplättchen (110) angespritzt oder das Trägerplättchen (110) bereichsweise mit dem Bürstenkörper umspritzt wird.

To manufacture toothbrushes, in a first manufacturing step, a carrier plate (110) is formed with a soft-elastic element (112) or several such elements and with holes (114) for fiber bundles in a two-component injection-molding tool. In a second manufacturing step, the carrier plate (110) with the soft elastic elements (112) and the holes (114) for the fiber bundles is introduced into a bristle tool in which fiber bundles are inserted into the holes and fixed to the carrier plate. In a third production step, the carrier plate (110) is introduced with the soft elastic elements (112) and with the attached fiber bundles in an injection mold in which the brush body or a part thereof molded on the carrier plate (110) or the carrier plate (110) in areas with the brush body is overmolded.
