Description

Die vorliegende Erfindung besteht darin, daß der* Schlüsselschaft und der Ring nach Art eines Splintes hergestellt sind. Ein freies Schaftende wird rechtwinklig abgebogen, worauf dann der Schlüsselbart in Form eines flachen MetaUstückes an beide Endteile zugleich angeschweißt wird und ein Nachpressen von Einsatz und Rillen in derselben Schweißhitze stattfindet. Die Bearbeitung des Bartes findet nicht wie bei den bekannten Verfahren vor, sondern nach dem Schweißen statt ohne vorherige Bearbeitung.The present invention is that the * key shaft and the ring after Kind of a split pin are made. A free end of the shaft is bent at right angles, whereupon the key bit in the form of a flat metal piece on both end parts at the same time is welded and a re-pressing of insert and grooves in the same Welding heat takes place. The processing of the beard does not take place as with the known Process before but after welding instead of without prior processing.

Es entsteht bei dem vorliegenden Verfahren absolut kein Abfall, und die Herstellung sticht daher durch Billigkeit und Festigkeit wesentlich von den anderen Verfahren ab. There is absolutely no waste in the present process, and the manufacturing process stands out therefore significantly different from the other methods in terms of cheapness and strength.
