Die Erfindung bezieht sich auf eine Maschine zum Bearbeiten von Häuten und Leder, bei welcher über dem zylindrischen heb- und senkbaren Werkstückauflagetisch und neben der Werkzeugwalze eine das Werkstück auf den Auflagetisch pressende Führungswalze angeordnet ist.The invention relates to a machine for processing hides and leather, in which above the cylindrical liftable and lowerable workpiece support table and next to the tool roller is a guide roller that presses the workpiece onto the support table is arranged.
Derartige Maschinen sind zwar schon bekannt, doch dient bei ihnen die neben derSuch machines are already known, but they are used next to the
ίο Werkzeugwalze liegende Walze, die sich zwangläufig mit dem Arbeitstisch dreht, nur zum Glattstreichen des Arbeitsstücks.ίο tool roller lying roller, which inevitably rotates with the work table, only to smooth the work piece.
Gemäß der Erfindung soll die neben der Arbeitswalze liegende Führungswalze als Treibwalze für den Auflagetisch dienen und unabhängig von der zylindrischen Werkstückauflage je nach dem Einschalten des Wendegetriebes das Werkstück der Werkzeugwalze zuführen oder von ihr fortziehen. Hierdurch wird erreicht, daß das Werkstück nicht gedreht oder gewendet zu werden braucht, um auf seiner ganzen Fläche bearbeitet zu werden, und daß eine besondere Einspannvorrichtung in Wegfall kommt. Die Arbeitsweise der in der Zeichnung dargestellten Maschine ist folgende:According to the invention, the guide roll lying next to the work roll is intended as a drive roll serve for the support table and independent of the cylindrical workpiece support depending on the switching on of the reversing gear, feed the workpiece to the tool roller or move away from her. This ensures that the workpiece does not rotate or needs to be turned so that it can be processed over its entire surface, and that a special jig is no longer required. How the machine shown in the drawing works is the following:
Das Werkstück ι wird auf die zylindrische heb- und senkbare Werkstückauflage 2 gelegt und mit einem Fußtritt 5 erst an die Führungswalze 4, dann an die Arbeitswalze 3 gepreßt. Durch die Führungswalze, die mit einem Wendegetriebe 6 versehen ist, wird das Werkstück 1 unter die Arbeitswalze 3 entweder nach vorn geschoben oder nach hinten zurückgezogen, so daß das Werkstück 1 in beiden Richtungen von der Werkzeugwalze 3 bearbeitet wird.The workpiece is placed on the cylindrical workpiece support 2 that can be raised and lowered and with a kick 5 first pressed against the guide roll 4, then against the work roll 3. Through the guide roll, which is provided with a reversing gear 6, the workpiece 1 is either under the work roll 3 pushed forward or withdrawn so that the workpiece is 1 in is processed by the tool roller 3 in both directions.
