Es besteht in der KunststoffIndustrie in den verschiedensten Bereichen das Bedürfnis, Kunststoffteile wie Platten, Bänder, Rohre, Stangen, Flanschen oder andere Formlinge zu verschweißen.It exists in the most diverse forms in the plastics industry Areas the need to use plastic parts such as plates, tapes, To weld pipes, rods, flanges or other molded parts.
Soweit es sich um das Verschweißen gleichartigen Kunststoffmaterials handelt, ist das Problem dadurch gelöst, daß auf bekannte Weise, wie zum Beispiel durch Spiegelschweißung, Heizelement schweißung, Draht schwei^u-'g, Re i bungs schweißung die zu verschweißenden Flächen bis zur Plastizität erwärmt und anschließend aufeinander gepresst werden. Diese bekannten Schweißmethoden führen jedoch nur dann zum Erfolg, wenn die zu verschweißenden Teile sich miteinander im plastischen Zustand verbinden.As far as the welding of similar plastic material is concerned, the problem is solved in that on known way, such as by mirror welding, heating element welding, wire welding, friction welding the surfaces to be welded are heated to plasticity and then pressed together. These well-known However, welding methods are only successful if the parts to be welded are in a plastic state associate.
Eine Schweißung, die hierbei in > edeutende1» Umfang angewendet wird, ist die Schweißung mit Heizelementen. Sie hat jedoch den Nachteil, daß immer nur der Kunststoff in einer schmalen Zone um die Heizdrähte herum plastifiziert wird. Dadurch entsteht im Kunststoff ein starker Temperaturgradient, so daß die Kunststoffmasse, die direkt dem Heizelement benachbart ist, schon dünnflüssig wird, während die weiter entfernt gelegenen Stellen noch relativ zäh plastisch sind. Durch diesen steilen Gradienten tauchen in der Schweißzone Spannungen auf. Darüber hinaus dauert wegen der geringen Oberfläche der Drähte die Schweißung relativ lang.A weld that is used to an> significant 1 »extent is welding with heating elements. However, it has the disadvantage that only the plastic is plasticized in a narrow zone around the heating wires. This creates a strong temperature gradient in the plastic, so that the plastic mass, which is directly adjacent to the heating element, is already thin, while the points further away are still relatively viscous. As a result of this steep gradient, stresses appear in the welding zone. In addition, because of the small surface area of the wires, the weld takes a relatively long time.

Eine Schweißeinlage, die diese Nachteile vermeldet, und dies ist der Gegenstand der vorliegenden Erfindung, wird im folgenden beschrieben.A sweat pad that reports these disadvantages, and this is the subject of the present invention, will hereinafter described.
Es handelt sich hierbei um eine Schweißeinlage zum Verschweißen von Kunststoffteilen, dadurch gekennzeichnet, daß zwischen den die Schweißnaht bildenden Kunststoffteilen sich eine den elektrischen Strom und die Wärme gut leitende Metallfolie befindet, die sich über die ganze Länge und Breite der gewünschten Schweißnaht erstreckt und auf beiden Seiten gegen den Kunststoff hin durch eine Folie abgedeckt ist, die sich im plastischen Zustand sowohl mit dem Metall als auch mit dem zu verschweißenden Kunststoff verbindet.It is a welding insert for welding plastic parts, characterized in that between the the plastic parts forming the weld seam are connected to the electrical Metal foil, which is a good conductor of electricity and heat, is located over the entire length and width of the desired weld seam extends and is covered on both sides against the plastic by a film, which is in the plastic state connects both with the metal and with the plastic to be welded.
Eine solche Schweißeinlage hat den Vorteil, daß sich Materialien, die an sich miteinander nicht verschweißbar sind, wie zum Beispiel Polyvinylchlorid und Polyäthylen durch die Vermittlung der Folie miteinander verbinden. Dies erfolgt dadurch, daß die am Metallband klebende Folie im zu verschweißenden Kunststoff durch die Erwärmung verankert wird.Such a welding insert has the advantage that there are materials that cannot be welded to one another, such as, for example Connect polyvinyl chloride and polyethylene through the intermediary of the foil. This is done in that the on the metal band adhesive film is anchored in the plastic to be welded by the heating.
Eine derartige Schweißeinlage hat durch die Ausdehnung der Metallfolie den weiteren Vorteil der gleichmäßigen Erwärmung der Schweißstelle auf einer beliebig großen Fläche,und durch die hohe Aufnahme an elektrischer Energie und der guten Weiterleitung der Wärme den Vorteil der raschen und gleichmäßigen Verschweißbarkeit.Such a welding insert has due to the expansion of the metal foil the further advantage of the uniform heating of the welding point over any large area, and the high absorption in terms of electrical energy and the good transfer of heat, the advantage of quick and even weldability.
Zeichnung 1 erläutert die Erfindung, ohne sie in irgendeiner Weise einzuschränken. Es bedeuten in dieser Zeichnung Nr. 1 und Nr. 2 die zu verschweißenden Kunststoffteile, Nr. 3 die eingelegte Metallfolie und Nr. k die eingelegten Polyäthylenfolien.Drawing 1 explains the invention without restricting it in any way. In this drawing, no. 1 and no. 2 mean the plastic parts to be welded, no. 3 the inserted metal foil and no. K the inserted polyethylene foils.
