Description
Die bisher gebräuchlichen Rasierklingen weisen meist scharfe Ecken auf, auf welche die meisten Hautverletzungen zuriickzuführen sind. Um Verletzungen zu vermeiden, hat man versucht, die Seitenteile oder Ecken mehr oder minder abzurunden. In der Praxis hat sich aber gezeigt, daß es zum Vermeiden von Hautverletzungen durch die Ecken nicht genügt, wenn die Rasierklingen beim Ausstanzen gerundete Ecken erhalten und danach das Scharfschleifen der Klingen erfolgt und wenn die Ecken in den Scharfschliff einbezogen werden. Bei der erfindungsgemäßen Rasierklinge wird die Schneide an den Ecken zur Vermeidung von Verletzungen nach :dem Ausstanzen und nach dem Scharfschleifen in einem weiteren Arbeitsgang stumpf, d. h. nicht mehr schneidend geschliffen. Dabei spielt es keine Rolle, ob die: nachträgliche Abstumpfung in Form einer Rundung oder in einem geraden Anschliff erfolgt.The razor blades used up to now mostly have sharp corners to which most skin injuries are attributable. About injuries To avoid this, attempts have been made to round off the side parts or corners more or less. In practice, however, it has been shown that it helps to avoid skin injuries the corners are not sufficient if the razor blades have rounded corners when punching out and then the blades are sharpened and when the corners are sharpened be included. In the razor blade according to the invention, the cutting edge is on the Corners to avoid injuries after: punching and after sharpening blunt in a further operation, d. H. no longer ground with cutting. Included It does not matter whether the: subsequent blunting in the form of a rounding or takes place in a straight grind.

Die Ecken und 3 sind entsprechend der erfindungsgemäßen Ra@s@ierklin:ge nach dem Ausstanzen und dem Scharfschliff in einem weiteren Arbeitsgang durch einen weiteren Anschliff nachträglich stumpf, d. h. nicht mehr schnendend geschliffen.Fig. I shows a razor blade with serrated sides, in which the corners I are sharpened in the usual way. The corners and 3 are corresponding to the Ra @ s @ ierklin: ge according to the invention after punching and sharpening in a further work step by a further bevel, subsequently blunt, d.

Die Ecken 6 und 7 sind entsprechend der erfindungsgemäßen Rasierklinge nach .dem Ausstanzen und dem Scharfschliff in einem weiteren Arbeitsgang durch einen weiterenAnschliff nachträglich stumpf, cl. b. nicht schneidend gemacht.Fig. 1I shows a razor blade with the sides following are rounded on the outside.
