Description

Vom Gegenstand des Hauptpatentes unterscheidet sich der Gegenstand der vorliegenden Erfindung dadurch, daß die Klemmzange als Klemmgabel α ausgebildet wird, an deren 5 offenem Ende zwei unter Federdruck stehende Rollen b angeordnet sind. Die Klemmgabel ist verschiebbar auf der Führungsstange c. Um bei dem exzentrischen Angriff der Kraft zur Verschiebung der Klemmzange das Ecken der Führung d auf der Führungsstange c zu vermeiden, sind die Rollen e angebracht. Statt der federnd gelagerten Rollen b können diese auch fest angeordnet sein, dann müssen aber die beiden Schenkel der Gabel α selbstfedernd oder scharnierartig ausgebildet und durch eine Feder so zusammengespannt werden, daß die Rollen beim Überfahren der Lötstelle einen kräftigen Druck auf die zu lötenden beiden Bandenden ausüben.The subject matter of the present invention differs from the subject matter of the main patent in that the clamping tong is designed as a clamping fork α, at the 5 open end of which two rollers b under spring pressure are arranged. The clamping fork is slidable on the guide rod c. In order to avoid the corners of the guide d on the guide rod c during the eccentric application of the force to move the clamping pliers, the rollers e are attached. Instead of the resiliently mounted rollers b , these can also be fixed, but then the two legs of the fork α must be self-resilient or hinge-like and clamped together by a spring so that the rollers exert a strong pressure on the two ends of the tape to be soldered when they pass over the soldering point exercise.

Diese Rollenklemmgabel hat gegenüber der Klemmzange den Vorzug, daß Unreinigkeiten, die sich auf beiden Seiten der Lötstelle durch Verbindung des Zunders mit dem Flußmittel bilden, durch die Rollen fortgeschoben werden, während sie in der Zange in die noch weichen Oberflächen der Lötstelle hineingedrückt werden und hier eine Schwächung des Querschnittes herbeiführen. DurchThis roller clamping fork has the advantage over the clamping pliers that impurities, which are formed on both sides of the solder joint by combining the scale with the flux, pushed away by the rollers while they are pressed into the still soft surfaces of the solder joint in the pliers and a weakening here of the cross-section. By

*) Früheres Zusatzpatent 398341 das Zusammenpressen der zu lötenden Bandenden mit der Klemmzange tritt auch ein so plötzliches, starkes Abkühlen der Lötstelle ein, daß diese glashart wird und durch nochmaliges Einschalten des Stromes ausgeglüht werden muß. Bei der Rollenklemmgabel tritt diese Abkühlung nicht ein, denn es genügt ein einmaliges Vor- und Zurückfahren der Rollen über die Lötstelle, um alle Teile der beiden zu lötenden Enden fest aufeinanderzupressen. *) Former additional patent 398341 the pressing together of the tape ends to be soldered with the clamping pliers there is also such a sudden, strong cooling of the solder joint one that this is as hard as glass and annealed by switching on the current again must become. This cooling does not occur with the roller clamping fork, because it is sufficient a single back and forth movement of the rollers over the solder joint to cover all parts of the firmly press both ends to be soldered together.

Die Verwendung der Rollenklemmgabel bedeutet deshalb eine wesentliche Verbesserung der Vorrichtung zum Löten dünner Stahlbänder.The use of the roller clamping fork therefore means a significant improvement the device for soldering thin steel strips.
