  1. PATENTANSPRUCH:
    Verfahren zum Erwärmen von zur Verbindung zweier Teile dienenden Schichten, insbesondere von Leim, durch elektrischen Strom, der einen oder mehrere in der Verbradungsfuge angeordnete Widerstandsleiter durchfließt, dadurch gekennzeichnet, daß als Widerstandsmaterial solche Stoffe, vorzugsweise niedrigschmelzende Metallegierungen, in solcher An- Ordnung dienen, daß bei Erreichen der für den Verbindungsvorgang erforderlichen Temperatur der Widerstandsleiter sich durch Schmelzen, Oxydieren od. dgl. auflöst und damit den elektrischen Stromkreis unterbricht.
