Description

Behandlung eines Stahlbandes für die Rasierklingenherstellung vor dem Zerteilen mittels mit Schneiden ausgestatteter Trennwerkzeuge Die Behandlung von Stahlbandstreifen zur Herstellung von Rasierklingen daraus für sogenannte Sicherheitsrasiergeräte gemäß der vorliegenden Erfindung bezweckt die Erleichterung des Zerteilens eines gehärteten, entsprechend der Form von Rasierklingen vor dem Härten gelochten und an den Abtrennstellen vorgekerbten Stahlbandes in die Einzelklingen bei Verwendung von mit Schneiden ausgestatteten Trennwerkzeugen.Treatment of a steel belt for the manufacture of razor blades cutting up using cutting tools equipped with cutting tools. Treatment of steel strip strips for the production of razor blades for so-called safety razors according to the present invention aims to facilitate the dicing of a hardened, perforated according to the shape of razor blades before hardening and pre-notched steel strip at the severing points in the individual blades when in use of cutting tools equipped with cutting edges.

Die den Erfindungsgegenstand bildende Behandlung derartiger und derartig vorbehandelter gehärteter Stahlbandstreifen besteht darin, daß diese Stahlbandstreifen mit einem Überzug aus weichem Metall, insbesondere aus Messing, versehen werden.The subject matter of the invention treatment of such and such pretreated hardened steel tape strip consists in that these steel tape strips be provided with a coating made of soft metal, in particular made of brass.

Durch diese Behandlungsart der gehärteten Stahlbandstreifen der vorliegenden Art wird erreicht, daß die an den Trennstellen entsprechend der Klingenform vorgekerbten Klingen sich besser und fehlbruchsicherer an diesen Einkerbungsstellen mittels mit Schneiden ausgestatteter Teilwerkzeuge abtrennen lassen als bei nicht mit derartigen weicheren Metallüberzügen nach der Härtung überzogenen Klingenbändern, weil die Schneiden der Teilwerkzeuge durch die Überzugsschicht aus weicherem Überzugsmetall hindurch auch die darunterliegende vorgekerbte Stahlbandschicht leichter bzw. glatter durchdringen.By this type of treatment the hardened steel strip strips of the present Art is achieved that the pre-notched at the cutting points according to the shape of the blade Sound better and more fail-safe at these notch points using Cut off the cutting of equipped part tools than in the case of not with such Blade bands coated with softer metal coatings after hardening because the Cutting the part tools through the coating layer of softer coating metal the pre-notched steel strip layer underneath is also lighter or smoother through it penetrate.
