Description
Verfahren und Einrichtung zum Festhalten der Schablone beim Zuschneiden Beim Zuschneiden von Folien, z. B. Lederfolien, in Stücke verschiedener Umrisse werden Schablonen verwendet, deren Form jener der gewünschten Folien- Teilstücke entspricht.
Der Arbeitsvorgang ist bisher folgender: Der Arbeiter presst mit einer Hand die Schablone auf die Folie und führt mit der andern das Messer der Schablonenkante entlang, bis das Folienstück in Form der Schablone ausgeschnitten ist.
Dieses Verfahren hat zwei Nachteile: Das Festhalten der Schablone ist sehr ermüdend. b) Der Raum oberhalb des Werkstückes ist nicht frei; die Stellung des aufgestützten Armes, der die Schablone niederdrückt, muss beim Umfahren derselben mit dem Messer geändert werden (Zeit verlust, Ungenauigkeit zufolge Gefahr des Ver- rutschens der Schablone).
Demgegenüber schlägt das erfindungsgemässe Ver fahren vor, die Schablone durch elektromagnetische Kraft festzuhalten. Zur Ausführung dieses Verfahrens werden unter dem Werktisch eine oder mehrere Drahtspulen mit Weicheisenkern angeordnet. Lässt man durch die Spule einen Strom fliessen, so ent steht ein magnetisches Feld, das durch die Werktisch platte hindurch wirkt und die auf die zuzuschneidende Folie aufgelegte eiserne Schablone festhält.
Method and device for holding the template when cutting When cutting foils, for. B. leather foils, stencils are used in pieces of different outlines, the shape of which corresponds to that of the desired foil sections.
So far, the process has been as follows: the worker presses the template onto the foil with one hand and guides the knife along the edge of the template with the other until the piece of foil is cut out in the form of the template.
This method has two disadvantages: Holding the stencil is very tedious. b) The space above the workpiece is not free; the position of the supported arm, which presses down the stencil, must be changed when the knife travels around it (loss of time, inaccuracy due to the risk of the stencil slipping).
In contrast, the inventive method suggests driving to hold the template by electromagnetic force. To carry out this process, one or more wire spools with a soft iron core are placed under the workbench. If you let a current flow through the coil, a magnetic field is created that acts through the worktop and holds the iron template placed on the foil to be cut.
