Dazu ist nach dem Hauptpatent die Anordnung so getroffen, daß die Kunststoffauflagen als Hetz, Gewebe, Gitter o. dgl. ausgeführt und durch die Durchbrechungen des Metallträgers hindurch miteinander verschweißt sind.» Zum Hauptpatent gehört nach bevorzugter Ausführungsform, daß die auf die Kunststoffauflagen feinporige Abdeckauflagen aufgeschweißt, sind, die ebenfalls aus Kunststoff bestehen. Diese funktionieren als feinfasriger Scheider« -Bei der Herstellung von Metall/Kmiststoff-Verbundelektroden nach dem Hauptpatent arbeitet man mit mechanischem Druck und Ultraschallschweißenergie, um die Kunststoffauflagen durch die Durchbrechungen des Metallträgers miteinander zu vereinigen^ - während do,s Ausschweißen der feinporigen Abdeckauflagen im allgemeinen durch Anwendung von Druck und Wärme erfolgt. Das alles hat sich bewährte Inzwischen wurde festgestellt, daßThe main patent 135 426 relates to a metal / Kiuiststoff composite electrode for batteries u, the like., With perforations having metal carrier and cover on both sides by a plastic pad , Vielhe plastic pad for receiving active masses set up and are provided with these «The H up patent is the task so on form such a metal / plastic composite electrode so that no damage occurs by volume change of the active materials in the charge-discharge game, while nonetheless a simple production is to be ensured. For this purpose, according to the main patent, the arrangement is such that the plastic supports as Hetz, fabric, grid o. The like. Executed and welded through the openings of the metal support are welded together. »To the main patent according to a preferred embodiment, that on the plastic supports finely porous Abdeckauflagen are welded, which are also made of plastic. These function as a fine-fiber separator. "In the production of metal / metal composite electrodes of the main patent, mechanical pressure and ultrasonic welding energy are used to join the plastic pads through the apertures of the metal carrier." - while welding the fine-pored cover pads generally done by applying pressure and heat. All this has proven itself Meanwhile, it was found that
