Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung bezieht sich auf eine Schleifvorrichtung für Lederbearbeitungsmaschinen, bei denen die Messerklingen schraubengangförmig auf einer Walze angeordnet sind und an der jeweiligen Schneide der Messerklingen ein Schleifkörper entlang geführt wird.The invention relates to a grinding device for leather processing machines, in which the knife blades are arranged helically on a roller and a grinding tool is guided along the respective cutting edge of the knife blades.

Nach der Erfindung werden die schraubengangförmig angeordneten Messerklingen unmittelbar nach dem Abschleifen noch vonAccording to the invention, the helically arranged knife blades are immediately after sanding still from

ίο einem hinter dem Schleifkörper angeordneten Stahl bearbeitet, der unter einem solchen Winkel zu der angeschliffenen Messerklinge steht, daß er an der Schneidkante des Messers einen schneidenden Grat erzeugt, ähnlich wie die Ziehklingen der Tischler einen solchen aufweisen.ίο one arranged behind the grinding wheel Machined steel that is at such an angle to the sharpened knife blade says that it creates a cutting burr on the cutting edge of the knife, similar to the carpenters' scrapers have one.

Auf der Zeichnung ist die Gratbildung gemäß der Erfindung dargestellt. Neben dem Schmirgelstein oder Schleifblock d, der in dem Halter f, f durch die Schraube h und das Handrad g nachstellbar ist, ist eine gehärtete Stahlgußscheibe i angebracht. Diese wird, nachdem die in der Messerwalze α sitzenden Messerklingen a1 durch den Schmirgelstein d geschliffen sind, gegen die Schneiden gedrückt, wodurch der scharfschneidende Grat α2 (Faden oder Linie) entsteht.The drawing shows the formation of burrs according to the invention. In addition to the emery stone or grinding block d, which can be readjusted in the holder f, f by means of the screw h and the handwheel g, a hardened cast steel disk i is attached. After the knife blades a 1 seated in the knife roller α have been ground by the emery stone d , this is pressed against the cutting edges, creating the sharp-cutting ridge α 2 (thread or line).
