Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruchs 1.The invention relates to a method according to the preamble of claim 1.
Bei einem nach der US-PS 24 35 441 bekannten Verfahren dieser Art ist die Walze mit dem positiven Pol und die Metallschicht mit dem negativen Pol der Gleichspannungsquelle verbunden. Mittel zur Stabilisierung der Gasentladung sind nicht vorgesehen. Die Gleichspannung kann bei diesem Verfahren größenordnungsmäßig bei 500 Volt liegen.In a method of this type known from US Pat. No. 2,435,441, the roller is with the positive pole and the metal layer with the negative pole of the DC voltage source tied together. Means for stabilizing the gas discharge are not provided. The DC voltage can be on the order of 500 volts with this method.
Nach der DE-PS 9 80 098 ist es bei einem ähnlichen Verfahren bekannt, die Gasentladung mit Hilfe einer Wechselspannung höherer Frequenz (400 bis 4000 Hz) zu erzeugen.According to DE-PS 9 80 098 it is known in a similar method, the gas discharge with the help of a Generate alternating voltage of higher frequency (400 to 4000 Hz).
Nach der DE-PS 5 88 369 ist ein Verfahren bekannt, bei dem Bereiche von auf Isolierkörpern aufgebrachten Metallschichten ebenfalls mittels eines durch eine Wechselspannung erzeugten elektrischen LichtbogensAccording to DE-PS 5 88 369 a method is known in which areas of applied to insulating bodies Metal layers also by means of an electric arc generated by an alternating voltage
entfernt werden.removed.
Aufgabe der Erfindung ist es, ein Verfahren nach dem Oberbegriff des Anspruchs 1 zu verbessern, daß es besonders zuverlässig istThe object of the invention is to provide a method according to the To improve the preamble of claim 1 that it is particularly reliable
Die Lösung dieser Aufgabe ist im Kennzeichen des Anspruchs 1 angegeben.The solution to this problem is given in the characterizing part of claim 1.
Der Lichtbogen bewirkt wegen seiner Stabilisierung eine exakt begrenzte Entfernung des wenigstens einen Randbereichs der auf dem Isoiierstoffolienband aefindlichen MetallschichtBecause of its stabilization, the arc causes an exactly limited distance of the at least one Edge area of the metal layer on the insulating film strip
Die Walze kann sich insbesondere entsprechend der US-PS 24 35 441 an einer Schneidemaschine befinden, in der das Band durch Zerteilung entsteht, oder an einer Wickelmaschine, die das Band mit anderen Bändern ühnlicher Art zu Kondensatoren wickelt Die Befreiung des Randbereichs von der Metallschicht kann an einer oder beiden Kanten des Bandes vorgenommen werden, je nachdem, ob nur eine Kante des Bandes oder beide Kanten des Bandes über die Metallwalze laufen.The roller can in particular be located on a cutting machine according to US-PS 24 35 441, in which the tape is created by cutting, or on a winding machine that connects the tape with other tapes Similar to capacitors wraps The Liberation the edge area of the metal layer can be made on one or both edges of the tape, depending on whether only one edge of the belt or both edges of the belt run over the metal roller.
Bevorzugte Ausführungsformen des Verfahrens sind in des Untcrsns^rüchen sncre<Tebcn.Preferred embodiments of the method are in the EBCN Untcrsns ^ rüchen sn cr e <T.
Die Zeichnung zeigt schematisch eine Vorrichtung zur Durchführung des Verfahrens.The drawing shows schematically an apparatus for carrying out the method.
Ober eine um eine Achse 2 drehbare Walze 4 ist ein auf seiner einen Seite zunächst vollflächig mit einer Metallschicht 6 versehenes und auf seiner anderen Seite unbedecktes Isolierslaffolienband 8 derart gezogen, daß es mit seiner unbedeckten Seite über die Walze 4 läuft Die Walze 4 erstreckt sich über beide Randbereiche des Isolierstoffolienbandes 8. Die Walze 4 liegt an einer gegenüber der Metallschicht 6 negativen Gleichspannung von 300 bis 2000 V. Diese Gleichspannung erzeugt zum Entfernen der Metallschicht 6 in den beiden Randbereichen Lichtbogen 10, 12 zwischen den Randbereichen und der Walze 4 über die jeweils zugehörigen Kanten des Isolierstoffolienbandes 8. Zur Stabilisierung der Lichtbogen 10,12 sind nadeiförmige Elektroden 14,16 vorgesehen, die an einer negativen. Gleichspannung von 3—15 kV gegenüber der Metallschicht liegen. Die Spitzen der nadeiförmigen Elektroden 14,16 weisen einen Abstand von 5—25 mm von den Lichtbögen 10,12 auf. Die angegebenen Maßzahlen sind bei den üblichen Stärken der Metallschicht 6, wie sie zur Herstellung von Wickelkondensatoren geeignet sind, ziemlich unabhängig von der Laufgeschwindigkeit des Isolierstoffolienbandes 8 im Bereich von 0,1 bis 5 m/sec.Above a roller 4 rotatable about an axis 2, one side is initially covered over with a metal layer 6 provided and uncovered on its other side Isolierslaffolienband 8 drawn in such a way that it runs with its uncovered side over the roller 4 The roller 4 extends over both edge areas of the Isolierstoffolienbandes 8. The roller 4 is connected to a negative DC voltage compared to the metal layer 6 from 300 to 2000 V. This DC voltage is generated to remove the metal layer 6 in the two edge areas Arc 10, 12 between the edge areas and the roller 4 over the respective associated edges of the insulating film strip 8. To stabilize the arcs 10, 12 are needle-shaped electrodes 14, 16 provided that on a negative. DC voltage of 3-15 kV against the metal layer. The tips The needle-shaped electrodes 14, 16 are at a distance of 5-25 mm from the arcs 10, 12. The specified dimensions are for the usual thicknesses of the metal layer 6, as they are for the production of Winding capacitors are suitable, pretty much independent of the running speed of the insulating foil tape 8 in the range from 0.1 to 5 m / sec.
Das Verfahren wurde mit besonderem Erfolg erprobt an einer 6 μπι starken, mit einer Aluminiumschicht versehenen Kunststoffolie bei Anlegen einer Spannung von 800 Volt Dabei wurden Randbereiche von 0,5 mm Breite sauber entferntThe method was tested with particular success on a 6 μm thick, provided with an aluminum layer Plastic film when a voltage of 800 volts was applied. Edge areas 0.5 mm wide were created cleanly removed
