Claims (3)

1. Stanzstempel- und Stanzplattenkombination, zur Verwendung in einer Standardpresse, um Zuschnitte von Streifenmaterial zu schneiden mit einer Stanzplatte (52), mit einer Öffnung, mit einem damit zusammenarbeitenden Stanzstempel (50), der einen diesem zugeordneten Gegenhalter (72) aufweist, wobei der Stempel so bemessen ist, daß er mit einem Arbeitsspiel in die öffnung paßt, wobei der Gegenhalter in der Plattenöffnung verschiebbar ist, um als eine Druckuntedage zu wirken, um das Streifenmaterial über der zu stanzenden Fläche zwischen ihm und dem Stempel festzuklemmen und um geschnittene Zuschnitte auszuwerfen, mit einem Abstreifer (86), der den Stempel zum Entfernen von überschüssigem Streifenmaterial um den Stanzstempel herum nach einer Stanzoperation umgibt, und mit Abstandshaltemittel (106, 108), die zwischen der Stanzplatte (52) und dem Abstreifer (86) angeordnet sind, um das Abstreifen zu erleichtern, dadurch gekennzeichnet, daß die Öffnung der Platte einen abgerundeten Rand aufweist (an sich beim Feinstanzen bekannt) mit einem Radius zwischen ungefähr 0,127 und 0,635 mm, daß das Arbeitsspiel nicht mehr beträgt als ungefähr 1% der Dicke des Streifenmateriales und zwar in Abhängigkeit von seiner Art und Dicke, und daß die Abstandshaltemittel von einer derartigen Stärke sind, daß während einer Stanzoperation die Stanzplatte (52) und der Abstreifer (86) genügend weit voneinander auf Abstand gehalten sind, um sicherzustellen, daß der umgebende bereich des Streifenmateriales dazwischen nicht eingeklemmt wird.
2. Kombination nach Anspruch 1, gekennzeichnet durch einen Lochstempel (66) und ein Lochgesenk (64), wobei sich der Lochstempel (66) durch den Gegenhalter (74) erstreckt und das Lockgesenk (64) von einer den Stanzstempel (50) durchsetzenden Bohrung (64) gebildet wird.
3. Kombination nach Anspruch 2, dadurch gekennzeichnet, daß der Lochstempel (66) einen abgerundeten Führungsrand besitzt.
