Schweißelektrode zum Aufschweißen von Zierleisten aus Kunststoff mit metallisierter Oberfläche Welding electrode for welding decorative strips made of plastic with a metallized surface

Als Zierleisten für die Innenausstattung mit Kunststoffolien, wie sie namentlich im Fahrzeugbau üblich sind, werden bisher gewöhnlich Aluminiumleisten oder Kunststoffleisten mit Metalleffekt verwendet. Pie Aufbringung der Aluminiumleisten erfolgt mit Hilfe von Klipsen, die durch die Pappe, z. B. die Türverkleidung, durchgesteckt und auf der Pappenrückseite umgebogen werden. Die Aluminiumleisten werden mit umgebogenen Enden geliefert, so daß diese auch an den Endstellen einen für den Betrachter befriedigenden aesthetisehen Eindruck ergeben. Ein Nachteil der üblichen Aluminiumleisten besteht jedoch darin, daß sie sich mit der Kunststoffunterlage, auf der sie befestigt sind, nicht homogen verbinden lassen. Dies führt dazu, daß nach längerem Gebrauch sich die Verbindung zwischen Unterlagen und Leiste lokkert, so daß letztere zum"Klappern" neigt. Bei denAs trim strips for interior fittings with plastic sheeting, as is customary in vehicle construction are, so far, aluminum strips or plastic strips with a metal effect are usually used. Pie The aluminum strips are applied with the help of clips that pass through the cardboard, e.g. B. the door panel, be pushed through and bent on the back of the cardboard. The aluminum strips are bent over with Ends supplied so that these are also at the end points a satisfactory for the viewer aesthetic impression. A disadvantage of the usual However, aluminum strips consists in that they cannot be bonded homogeneously to the plastic base on which they are attached. This means that after prolonged use, the connection between the base and the bar loosens, so that the latter tends to "rattle". Both

Zierleisten mit metallisierter Oberfläche ist dieser Nachteil ausgeschlossen, da sich hier eine homogene Verbindung zwischen Zierleiste und Kunststoffunterlage nach dem Verfahren der Hochfrequenzschweißung erzielen laßt.Decorative strips with a metallized surface do not have this disadvantage, since they are homogeneous Connection between the decorative strip and the plastic base using the high-frequency welding process let achieve.

Schwierigkeiten bereitet hier jedoch eine befriedigende aesthetische Gestaltung der Zierleistenenden. Man hat sich deshalb bisher damit begnügen müssen, entweder die Enden der Zierleiste gerade abzuschneiden und die Zierleiste in dieser form aufzuschweißen, oder aber das Leistenende im Verlaufe des Schweißvorganges breit zu drücken. Bei der ersten Ausführungsform erstreckt sich daher der Metalleffekt nicht über die abgeschnittenen Enden, so daß die darunter liegende Kunststoffschicht erkennbar wird. Bei der zweiten Ausführungsform ist der Metalleffekt zwar auch an den Enden erhalten, doch haben diese hier ein Aussehen, das etwa einem breitgedrückten Pfennigstück entspricht. Beide Ausführungsformen ergeben für das Auge einen unbefriedigenden aesthetischen Eindruck. Es wurde nun gefunden, daß die geschilderten lachteile dadurch vermieden werden können, wenn man die Zierleiste in der Weise mit der Unterlage verschweißt, daß man das Ende bzw. die Enden der aufzuschweißenden Zierleiste auf der der metallisierten Seite abgekehrten Fläche schräg zuschneidet und anschließendDifficulties are presented here, however, with a satisfactory aesthetic design of the trim ends. So far, you have had to be content with either just cutting off the ends of the decorative strip and to weld on the decorative strip in this form, or the strip end in the course of the welding process wide to press. In the first embodiment, therefore, the metallic effect does not extend over the cut ends so that the layer of plastic underneath can be seen. In the In the second embodiment, the metallic effect is also retained at the ends, but these have one here Appearance that roughly corresponds to a penny pressed wide. Both embodiments result for the Eye an unsatisfactory aesthetic impression. It has now been found that the disadvantages described this can be avoided if the decorative strip is welded to the base in such a way that that one the end or the ends of the to be welded Trim the decorative strip on the surface facing away from the metallized side and then cut it at an angle

bei der vollflächigen Yerschweißung das schräg ge- k schnittene Ende bzw. die Enden während des Schweißvorganges biegt und gegen die zu verschweißende fläche drückt. Gegenstand der vorliegenden Neuerung ist eine Schweißelektrode, welche die Ausführung des eben erwähnten Verfahrens ermöglicht. Diese Schweißelektrode ist neuerungsgemäß dadurch gekennzeichnet, daß ihr Ende bzw. ihre Enden eine sich von der Basisfläche zu der Endkante der Schweißelektrode verlaufende bogenförmige Krümmung aufweisen.In the case of full-surface welding, the obliquely k- cut end or the ends bend during the welding process and press against the surface to be welded. The subject of the present innovation is a welding electrode which enables the above-mentioned method to be carried out. According to the invention, this welding electrode is characterized in that its end or ends have an arcuate curvature extending from the base surface to the end edge of the welding electrode.

Die feuerung ist an Hand der Pig. I bis III näher erläutert. The firing is on the pig's hand. I to III explained in more detail.
