Description

Klinge für Schneidwerkzeuge, insbesondere für Rasierklingen 1--, Ist hekinnt, daß künstlicher Korund und Spinell eine außerordentliche Härte aufweisen. Diese Werkstoffe Nverden daher bereits züi Schleifscheiben -,-erarbeitet und auch als Poliermittel verwcnAet. 1,-Irfiti,(Ititigsg-ei-näß wird eine ganz andersartige, Verwertung dieser Eigenschaften vor-#I'('Schla,-en, nämlich die VerwenAung von künstlichein Korund bzw. Spinell als Werkstoff für Klingen von Schneidwerkzeugen, insbesondere für Rasierklingen. Nach (lern Verneuilschen Verfahren gefingt es bekanntlich, künstlichen Korund und Spinell in Form von Kristallbirnen schon in beträchtlichen Gr(*')ßeri technisch herzustellen. Atts diesen Atisgangsstoffen werden erfindungsgemäß die den Klitigenkörper bildenden Plattcii herausg(schnitten, die in ihren Außenkanten sodann mit angeschlill'eneu Schneiden versehen werden können. E-s hat sich herausgestellt, daß infolge der den Härten der N#atursteine entsprechenden großen Härte der künstlichen. Korunde bzw. Spinelle derartige Klingen im Vergleich m#it den üblichen aus Stahl gefertigten KI:ingen eine viel geringere Ab- nutzung aufweisen, so daß ein Stumpfwer#den weitgehend. vermieden und ein Nachschleifen bzw. Ab- ziehen der Klingen nicht notwend,ig wird.. Hi`erdurch wird dic Gel)ratichsfähilgke#it der Korundbz,%v. Spinellklingen weitgehend gegenüber Stahlklingen verlängert, was insbesondere für Rasierklingen von besonderer Wichtigkeit isst.Blade for cutting tools, especially for razor blades 1-, It is hekinnt that artificial corundum and spinel have an extraordinary hardness. These materials are therefore already being worked out for grinding wheels and also used as polishing agents. 1, -Irfiti, (Ititigsg-ei-näß a completely different kind of utilization of these properties is proposed, namely the use of artificial corundum or spinel as a material for blades of cutting tools, especially for razor blades . After (Verneuilschen method Atts learning gefingt it is well known, industrially produce artificial corundum and spinel in the form of crystal pears already in considerable Gr (* ') ßeri. these Atisgangsstoffen according to the invention the the Klitigenkörper forming Plattcii eds (cut, which then in their outer edges with It has been found that, as a result of the great hardness of the artificial corundum or spinels, corresponding to the hardness of the natural stones, such blades are much lower in comparison with the usual steel made blades have wear and tear, so that a Stumpfwer # the largely avoided. and regrinding or waste not pull the blade notwend, ig is .. This makes the gel) ratichsbarkeit # it the corundum,% v. Spinel blades are largely elongated compared to steel blades, which is particularly important for razor blades.

Für die Herstellung von Rasierkliingen verwenidet man Plättchen von künstlichem Korund oder Spinell der entsprechenden Dicke, die an einer oder an zwei Seiten mit angeschliffenen Schneiden versehen werden und außerdem die für das Festhalten: im Rasierapparat erforderlichen Bohrungen. aufweisen können. Diese Bohrungen könam wegfallen, wenn die Klingen in Rasierapparaten mit Klernmvorrichtungen benutzt werdensollm Die Korundklingen können in Rasierapparaten mit flach liegender Klinge ohne Abänderung des Apparat-es verwendet werden. M gerwissen Artenvon Apparaten,' bei denendie Klinge schräg liegt, den sogenannten Schrägschnittapparaten, um einen sogenannten ziehenden Schnitt zu erzielen, kann es zweckmäßig rein, eine ati§ zwei Einzelteilen bestehende Korund- oder Spinellklinge zu benutzen.For the production of razor blades one uses platelets from artificial corundum or spinel of the appropriate thickness attached to one or two Sides are provided with beveled cutting edges and also those for holding: in the Shaver holes required. can have. These Holes can be omitted if the blades in razors with clamping devices The corundum blades can be used in razors with flat lying Blade without modification of the apparatus-it can be used. Little-known types of apparatus, ' in which the blade is inclined, the so-called bevel cutting devices, by one To achieve what is known as a pulling cut, it can be useful to have one ati§ two Using existing corundum or spinel blades.
