Abstract
Zur Herstellung von Zahnbürsten wird in einem ersten Herstellungsschritt ein Trägerplättchen mit einem weichelastischen Element oder mehreren solchen Elementen sowie mit Löchern für Faserbündel in einem Zweikomponenten-Spritzgießwerkzeug geformt. In einem zweiten Herstellungsschritt wird das Trägerplättchen mit den weichelastischen Elementen und mit den Löchern 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 mit den weichelastischen Elementen und mit den befestigten Faserbündeln in ein Spritzgießwerkzeug eingebracht, in dem der Bürstenkörper oder ein Teil davon an dem Trägerplättchen angespritzt oder das Trägerplättchen bereichsweise mit dem Bürstenkörper umspritzt wird.To produce toothbrushes, a carrier plate with a soft elastic element or several such elements and with holes for fiber bundles is formed in a two-component injection molding tool in a first production step. In a second production step, the carrier plate with the soft elastic elements and with the holes for the fiber bundles is introduced into a bristle tool, in which fiber bundles are inserted into the holes and attached to the carrier plate. In a third manufacturing step, the carrier plate with the soft elastic elements and with the attached fiber bundles is introduced into an injection molding tool, in which the brush body or a part thereof is molded onto the carrier plate or the carrier plate is partially overmolded with the brush body.
Description
Die Erfindung betrifft ein Verfahren zur Herstellung von Bürsten, insbesondere Zahnbürsten.The invention relates to a method for producing brushes, in particular toothbrushes.
Traditionell erfolgt die Befestigung von Borstenbündeln oder Faserbündeln an Bürstenkörpern mittels Schlingen oder metallischen Ankerplättchen. Bei Verfahren, die ohne Schlingen oder Ankerplättchen auskommen, werden Faserbündel an Trägerplättchen befestigt, indem ihre Befestigungsenden in Löcher des Trägerplättchens eingeführt und auf dessen Rückseite verschmolzen werden. Mit diesem „ankerlosen” Verfahren können Faserbündel in nahezu beliebiger Querschnittsform verarbeitet werden. Es besteht vielfach der Wunsch, außer den üblichen Borsten und Faserbündeln auch Reinigungselemente in das Borstenfeld zu integrieren (z. B. Reinigungselemente aus weichelastischem Material, Stifte, Stäbchen, Plättchen usw.). Zu diesem Zweck werden die Trägerplättchen mit zusätzlichen Löchern oder Aussparungen versehen, in die das weichelastische Material mit einer Spritzgießtechnik eingebracht wird. Je höher die Ansprüche an die Gestaltung und Funktionalität der Bürsten sind, desto komplexer und aufwendiger wird ihre Herstellung.Traditionally, the attachment of bristle bundles or fiber bundles to brush bodies by means of slings or metallic anchor plates. In processes that do not require loops or anchor plates, fiber bundles are attached to carrier platelets by inserting their attachment ends into holes in the carrier plate and fusing them to the back thereof. With this "anchorless" method fiber bundles can be processed in almost any cross-sectional shape. There is often the desire, in addition to the usual bristles and fiber bundles and cleaning elements in the bristle field to integrate (eg cleaning elements made of soft elastic material, pins, rods, plates, etc.). For this purpose, the carrier plates are provided with additional holes or recesses, in which the soft elastic material is introduced by an injection molding technique. The higher the demands on the design and functionality of the brushes, the more complex and expensive their production becomes.
Mit dem erfindungsgemäßen Verfahren, das in den beigefügten Patentansprüchen angegeben ist, werden die Vorteile der spritztechnischen Herstellung mit denen der ankerlosen bzw. schlingenlosen Befestigungstechnik vereint, um auch komplexe Bürstenausführungen rationell herstellen zu können.With the method according to the invention, which is specified in the appended patent claims, the advantages of the injection molding production are combined with those of the anchorless or loopless fastening technique, in order to be able to produce even complex brush designs efficiently.
