Description

Die Erfindung betrifft ein Verfahren zum Befestigen von Borstenbüscheln für Bürsten an Trägern aus thermoplastischem Kunststoff, die in Bürstenkörper eingebaut werden.The invention relates to a method for fastening bristle tufts for brushes on supports made of thermoplastic, the be installed in the brush body.

Zur Herstellung von Bürsten können Bürstenkörper mit einem Lochfeld bereitgestellt werden, das dem gewünschten Borstenfeld entspricht. Die Borstenbündel werden dann in die Löcher des Bürstenkörpers eingesetzt und darin verankert. Die Verankerung der Borstenbüschel im Bürstenkörper mittels Ankerplättchen oder Schlingen erfordert aber sehr leistungsfähige und daher aufwendige Maschinen.To make brushes, brush bodies with a Hole field are provided, the desired bristle field equivalent. The bundles of bristles are then in the holes of the Brush body inserted and anchored in it. Anchoring the Bristle tufts in the brush body using anchor plates or loops but requires very powerful and therefore complex machines.

Nach einem alternativen Bürstenherstellungsverfahren werden die Borstenbüschel an einem Träger befestigt, der dann in einen Bürstenkörper eingebaut wird, beispielsweise beim Spritzgießen eingeformt wird. Der im allgemeinen plättchenförmige Träger wird mit Löchern entsprechend dem gewünschten Lochbild versehen. Die Borstenbüschel werden in die Löcher eingesetzt, wobei auf einer Fläche des Trägers die nutzungsseitigen Enden der Borstenbüschel und auf der gegenüberliegenden Seite die in der Bürste zu verankernden axialen Enden der Borstenbüschel geringfügig herausragen. Diese in dem Bürstenkörper zu verankernden Enden der Borstenbüschel werden dann erhitzt, miteinander verschmolzen und zu einer Verdickung umgeformt. According to an alternative brush manufacturing process, the Tufts of bristles attached to a carrier, which is then in a brush body is built in, for example molded during injection molding becomes. The generally platelet-shaped carrier becomes with holes according to the desired hole pattern. The tufts of bristles are inserted into the holes, being on one surface of the support the usage-side ends of the bristle tufts and on the opposite Side the axial ends of the to be anchored in the brush The bristle tufts protrude slightly. This in the brush body too Anchoring ends of the tufts of bristles are then heated together fused and formed into a thickening.

Um einen ausreichenden axialen Halt der Borstenbüschel in den Trägern zu gewährleisten, ist in der DE 197 38 256 C2 vorgeschlagen worden, die plättchenartigen Träger mit pilzartigen Vorsprüngen zu versehen, die von dem geschmolzenen Material der Borsten untergriffen werden, so daß ein Formschluß zwischen den pilzartigen Vorsprüngen und der plastisch verformten Masse der Borstenbüschel entsteht. Dieses Verfahren erfordert jedoch einen erheblichen Aufwand zur Bereitstellung der plättchenförmigen Träger mit einer Vielzahl von pilzartigen Vorsprüngen.To ensure a sufficient axial hold of the bristle tufts in the To ensure carriers is proposed in DE 197 38 256 C2 been the plate-like carriers with mushroom-like projections provided that the molten material of the bristles underneath be so that a positive connection between the mushroom-like projections and the plastically deformed mass of the bristle tufts is created. This However, the process requires considerable effort in terms of provision the platy carrier with a variety of mushroom-like Projections.

Aus der EP-A-0 405 204 ist ein Verfahren und eine Vorrichtung zum Herstellen von Borstenfeldern bekannt. Die Vorrichtung weist eine Halteplatte auf, die mit Löchern zur Aufnahme von Borstenbüscheln versehen ist. Die Borstenbüschel ragen an ihrem einen Ende im eingeführten Zustand über die Halteplatte hinaus, wobei die einzelnen Borsten eines Borstenbüschels sowie Borsten benachbarter Borstenbüschel mittels eines beheizbaren Stempels miteinander verschmolzen werden. Zusätzlich dazu ist vorgesehen, daß die Halteplatte Noppen aufweist, die zusammen mit den Borsten durch den beheizbaren Stempel mit den Borsten der Borstenbüschel verschmolzen werden kann.From EP-A-0 405 204 is a method and an apparatus for manufacturing known from bristle fields. The device has a holding plate which is provided with holes for receiving tufts of bristles. The tufts of bristles protrude at one end in the inserted state beyond the holding plate, the individual bristles of a tuft of bristles and bristles of neighboring bristles Bristle tufts fused together using a heatable stamp become. In addition to this, it is provided that the holding plate has knobs that together with the bristles through the heatable stamp with the bristles of the Bristle tufts can be fused.

Durch die Erfindung wird ein Verfahren zum Befestigen von Borstenbüscheln für Bürsten an Trägern aus thermoplastischem Kunststoff geschaffen, durch das mit einfachsten Verfahrensschritten eine sichere Verankerung der Borstenenden in den Trägern gewährleistet wird. Gemäß der Erfindung wird vorgeschlagen, daß ein erhitzter Stempel mit Vorsprüngen zwischen den Löchern in die Masse der Träger eindringt und diese erweicht sowie seitlich bis in die Zwischenräume zwischen den Borsten der Borstenbüschel verdrängt. Bei diesem Vorgang wird zunächst das Material der Träger erweicht und verformt, so daß es die Enden der Borstenbüschel eng umschließt und durch Eindringen in die Zwischenräume zwischen den Borsten einen engen Formschluß herstellt. Bei der bevorzugten Ausführungsform des Verfahrens wird dann der Stempel mit seiner zwischen den Vorsprüngen gelegenen Fläche an den axialen Enden der Borstenbüschel angedrückt, wobei die verdrängte Masse der Borsten über die verformte Masse des Trägers greift. Auf diese Weise entsteht ein inniger Verbund zwischen den Trägern und den Borstenbüscheln. Die Vorsprünge umgreifen dabei die axialen Enden der Borstenbüschel und geben der verschmolzenen Kunststoffmasse eine genau vorgegebene Form. Während dieses Vorgangs werden die Borstenbüschel vorzugsweise axial gehalten oder abgestützt, so daß sie in den Löchern des Trägers nicht axial verschoben werden. The invention provides a method for attaching tufts of bristles for brushes on supports made of thermoplastic created a safe with the simplest procedural steps Anchoring the bristle ends in the carriers is guaranteed. According to the invention proposes that a heated stamp with Protrusions between the holes penetrate into the mass of the carrier and this softens and laterally into the spaces between the bristles of the bristle tufts repressed. In this process, the material of the Carrier softens and deforms so that it ends the bristle tufts tightly encloses and by penetrating the gaps between the Bristles creates a tight fit. In the preferred embodiment The procedure will then use the stamp with its in between the protrusions located at the axial ends of the bristle tufts pressed, the displaced mass of the bristles over the deformed mass of the carrier engages. This creates a intimate bond between the straps and the bristle tufts. The Projections encompass the axial ends of the bristle tufts and give the fused plastic mass a precisely specified shape. During this process, the tufts of bristles preferably become axial held or supported so that they are not in the holes of the wearer be moved axially.

Gegenstand der Erfindung ist auch eine Vorrichtung zur Durchführung des Verfahrens bestehend aus einem entsprechend einem gewünschten Lochbild mit Löchern versehenen Träger und in den löchern eingesetzten Borstenbüscheln und einem beheizbaren Stempel mit einer Angriffsfläche, die eine Vielzahl von Vorsprüngen aufweist, die entsprechend dem Lochbild des Trägers angeordnet sind, wobei beim Eindringen der Vorsprünge zwischen den Löchern in die Masse des Trägers die Masse erweicht sowie seitlich bis in die Zwischenräume zwischen den Borsten der Borstenbüschel verdrängt wird. The invention also relates to a device for carrying out the Method consisting of a hole pattern corresponding to a desired hole pattern provided carrier and in the tufts of bristles inserted and a heatable Stamp with an attack surface that has a plurality of projections, the are arranged according to the hole pattern of the carrier, with penetration the protrusions between the holes in the mass of the carrier the mass softens and laterally into the spaces between the bristles of the Bristle tufts are displaced.
