Abstract

Bei einem Stanzwerkzeug zum Schneiden von kunststoffbasierten Folienelementen (12), mit einer Stanzstempeleinheit (13), die mehrere Messerträger (21) aufweist, an denen jeweils wenigstens ein einen sich zu einer Schneidkante (32) verjüngenden Schneidkeil (31) aufweisendes Stanzmesser (25a, 25b) befestigt ist, und mit einer der Stanzstempeleinheit (13) zugeordneten, dieser gegenüberliegenden Matrize (14) zur Aufnahme des zu bearbeitenden Folienelements (12), wobei die Stanzstempeleinheit (13) gegenüber der Matrize (14) bei einem in einer Hubrichtung (15) erfolgenden Stanzhub zwischen einer Ausgangsposition (16) und einer Bearbeitungsposition (17) relativ beweglich gelagert ist, wobei die Schneidkeile (31) der Stanzmesser (25a, 25b) in der Bearbeitungsposition (17) in das zu bearbeitende Folienelement (12) eintauchen und in Abhängigkeit von deren Eintauchtiefe entlang einer Kantenlänge der Schneidkante (32) eine Schnittlinie (43) oder eine Brechlinie (44) im Foliensystem (12) erzeugen, sind die Schneidkanten (32) der Stanzmesser (25a, 25b) so konturiert sind, dass sie jeweils einen Kantenabschnitt (37; 37a, 37b) aufweisen, der bezüglich einer zur Hubrichtung (15) rechtwinkligen Referenzlinie (38) geneigt ist.In a punching tool for cutting plastic-based film elements (12), with a punch unit (13) which has several knife carriers (21), on each of which at least one punching knife (25a, 25b) is attached, and with a die (14) which is assigned to the punch unit (13) and is located opposite it for receiving the film element (12) to be processed, the punch unit (13) being positioned opposite the die (14) in a stroke direction (15 ) taking place punching stroke between a starting position (16) and a processing position (17) is mounted relatively movably, wherein the cutting wedges (31) of the punching knives (25a, 25b) in the processing position (17) dip into the film element (12) to be processed and into Depending on the depth of immersion along an edge length of the cutting edge (32), generate a cutting line (43) or a breaking line (44) in the film system (12), see FIG ind the cutting edges (32) of the punching knives (25a, 25b) are contoured so that they each have an edge section (37; 37a, 37b) which is inclined with respect to a reference line (38) at right angles to the stroke direction (15).
