Description

Lederschärfmaschine mit Ringmesser, Andrücker und Vorschubwalze. Die vorliegende Erfindung bezweckt, das Werkstück selbsttätig durch die Lederschärfrxias'chine hindurch zu führen. Bekanntlich wird die selbsttätige Führung dadurch erreicht, daß durch ein Kräftepaar leine drehende Wirkung auf das Werkstück ausgeübt wird, so daß es vor der Messerschneide gegen den dort angeordneten Anschlag gedrückt wird, wodurch es an diesem entlang geführt wird. Gemäß vorliegender Erfindung wird bei beliebig geformtem .Andrücker das Kräftepaar dadurch gebildet, daß die Vorschubwalze nur nahe am Rande, nahe der abzuschärfenden Kante des Werkstückes angreift und daneben eine oder mehrere bremsend wirkende Andrückfedern angeordnet sind.Leather sharpening machine with ring knife, presser and feed roller. the The purpose of the present invention is to automatically cut the workpiece through the leather sharpening machine to lead through. It is well known that automatic guidance is achieved by that a line rotating effect is exerted on the workpiece by a couple of forces, so that it is pressed against the stop located there in front of the knife edge, whereby it is guided along this. According to the present invention, at arbitrarily shaped .Andrücker the force couple formed by the fact that the feed roller attacks only close to the edge, close to the edge of the workpiece to be sharpened and next to it one or more brake-acting pressure springs are arranged.

Eine Ausführung der Erfindung ist auf der Zeichnung dargestellt, und zwar ist Abb. r eine Ansicht auf das Messer,. Abb. a ein Querschnitt.An embodiment of the invention is shown in the drawing, and although Fig. r is a view of the knife ,. Fig.a a cross section.

Das Messer a soll von dem Werkstück b den Teil c abtrennen. Zu diesem Zwecke wird das Werkstück b durch den entsprechend geformten und eingestellten Andrücker d so weit abgebogen, daß dieser Teil unter die Messerschneide gelangt. Das Werkstück wird durch die Vorschubwalze e vorgeschoben, und zwar greift nur .ein besonders gebildeter, kegelförmiger Ring f dieser Walze an das Werkstück c an. Neben diesem Ring f . sind,: in einer Ringnut k der Vorschubwalze liegend, Federn g angeordnet, die mittels der Schrauben h quer zur Achse der Vorschubwalze an der Auflageplatte i befestigt sind und sich von. unten gegen das Werkstück b legen, Durch die vorschiebende Wirkung des Ringes f und durch die bremsende Wiikung der Federn g wird das Kräftepaar gebildet und der gewünschte Erfolg erzielt.The knife a is to cut off the part c from the workpiece b. To this Purpose is the workpiece b by the appropriately shaped and set presser d bent so far that this part gets under the knife edge. The workpiece is advanced by the feed roller e, and only one in particular engages formed, conical ring f this roller on the workpiece c. Besides this Ring f. are: lying in an annular groove k of the feed roller, springs g arranged, by means of the screws h transversely to the axis of the feed roller on the platen i are attached and different from. lay down against the workpiece b, through the advancing one The effect of the ring f and the braking action of the springs g creates the force couple educated and achieved the desired success.
