Die genannte Aufgabe wird gemäß der Erfindung dadurch gelöst, daß eine kreisrunde Ausbrennscheibe mit der Stärke, die der Breite der auszubrennenden Streifen entspricht, als Ausbrennelektrode zwischen zwei Umlenkrollen federnd gegen die Metallisierung der freitragend geführten metallisierten Isolierstofffolie gedrückt wird.The stated object is achieved according to the invention by that a circular burn-out disk with the thickness corresponding to the width of the strips to be burned out, as the burn-out electrode between two deflection rollers resiliently against the metallization of the self-supporting metallized insulating film is pressed.
Das erfindungsgemäße Verfahren hat den Vorteil eines einfachen Aufbaus; insbesondere müssen keine Bänder gev/echselt werden, was eine Zeitersparnis bedeutet, da das Einfädeln neuer Bänder zeitraubend ist. Außerdem wirkt sich vorteilhaft aus, daß die Qualität des entmetallisierten Streifens nicht von der Oberflächenbeschaffenheit der Umlenkrollen abhängig ist, da die Entmetallisierung zwischen zwei Umlenkrollen erfolgt. Auch Folienfalten, die auf einer Umlenkrolle zu Störungen führen, wirken sich bei diesem Verfahren nicht störend aus, da sie glattgedrückt werden.The method according to the invention has the advantage of a simple structure; in particular, no straps have to be changed / changed, which means a time saving as threading new tapes is time consuming. In addition, it is advantageous that the The quality of the demetallized strip does not depend on the surface finish the pulleys is dependent, since the demetallization takes place between two pulleys. Even Foil folds, which lead to malfunctions on a deflection roller, do not have a disruptive effect in this process, as they be pressed flat.
Das erfindungsgemäße Verfahren wird vorteilhaft durchgeführt, indem eine Vorrichtung zum Einsatz kommt, die gekennzeichnet ist durch eine oder mehrere rotierende AusbrenEscheiben auG einem gegen Aluminium beständigen Sintermaterial. Vorteilhaft werden langsam rotierende Ausbrennscheiben mit einer gemeinsamen, nicht federnd gelagerten Achse für mehrere Ausbrennscheiben in einer Vorrichtung eingesetzt und eine Folienführung verwendet, die die Folien im Bereich der Ausbrennscheiben unter einer konstanten mechanischen Spannung hält und die Folien gegen die Ausbrennscheiben drückt.The method according to the invention is advantageously carried out by using a device which is characterized is made up by one or more rotating burnout disks a sintered material that is resistant to aluminum. Slowly rotating burnout disks with a common, Non-spring-mounted axle for several burn-out disks used in one device and a film guide used, which holds the foils in the area of the burn-out panes under constant mechanical tension and counteracts the foils pushes the burn-out disks.
Eine derartige Vorrichtung ist einfach aufgebaut; die Folien erzeugen auf Grund ihrer Elastizität die nötige Spannung und legen sich in einem gewissen Bereich an die Ausbrennscheiben an. Eine gute Standfestigkeit der Ausbrennscheiben wird erreicht, wenn diese zumindest im Bereich, der mit der Metallisierung in Berührung kommt, aus Bornitrid oder Titandiborid bestehen.Such a device has a simple structure; Due to their elasticity, the foils generate the necessary tension and lie against the burn-out disks in a certain area. A good stability of the burn-out disks is achieved, if this is made of boron nitride or titanium diboride, at least in the area that comes into contact with the metallization exist.

Zur Einstellung der gewünschten Torspannung wird zweckmäßig eine Einrichtung an der erfindungsgemäßen Vorrichtung angebracht, die zur Einstellung der Eindringtiefe der Ausbrennscheiben in die Folienlaufbahn dient.To set the desired door tension, a device is expediently attached to the device according to the invention, which is used to adjust the depth of penetration of the burn-out disks into the film track.
Zur Reinigung der Ausbrennscheiben von sich, anlagerndem Abrieb bzw. Niederschlag von Metall und von Oxyden wird dieser Niederschlag vorteilhaft durch eine rotierende Bürste, z.B. Stahldrahtbürste, entfernt. Dabei wird zweckmäßig die Reinigung kontinuierlich durchgeführt und die Geschwindigkeit der Rotation der Ausbrennscheiben so eingestellt, daß einerseits noch ein guter Kontakt zur Metallisierung erhalten bleibt, andererseits eine vollständige Entfernung des Niederschlages gewährleistet ist.For cleaning the burn-out panes from accumulated abrasion or precipitation of metal and oxides, this precipitation is advantageously achieved by means of a rotating brush, e.g. a steel wire brush, removed. The cleaning is expediently carried out continuously and the speed of rotation of the burn-out disks are set so that, on the one hand, good contact with the metallization is maintained, on the other hand complete removal of the precipitate is guaranteed.
Die Erfindung wird nun an Hand einer Figur näher erläutert.The invention will now be explained in more detail with reference to a figure.
Eine Folie 1 mit einer schraffiert dargestellten Metallisierung 2 läuft über ümlenkrollen 3 und 4 und wird dadurch gegen eine Ausbrennscheibe 5 gedrückt, welche in Pfeilrichtung A langsam rotiert. Über eine Spannungszuführung 6 wird die Ausbrennscheibe 5 mit einem Pol einer Spannungsquelle verbunden, während die Metallisierung 2 über die Rollen 3 und 4 mit Masse sowohl kapazitiv als auch galvanisch verbunden wird.A film 1 with a hatched metallization 2 runs over guide rollers 3 and 4 and is thus against a The burn-out disk 5 is pressed, which rotates slowly in the direction of the arrow A. The burn-out disk is via a voltage supply 6 5 connected to one pole of a voltage source, while the metallization 2 is connected both capacitively and galvanically to ground via the rollers 3 and 4.
Als Ausbrennspannung wird vorteilhafterweise eine hochfrequente Wechselspannung oder eine pulsierende Gleichspannung mit einer Mindestfrequenz um 100 kHz verwendet.A high-frequency alternating voltage or a pulsating direct voltage with a Minimum frequency around 100 kHz used.
Niederschläge von Metall oder Metalloxid auf der Ausbrennscheibe werden durch die Bürste 7 entfernt. Die Bürste 7 rotiert in Richtung B, also entgegen der Laufrichtung der Ausbrennscheibe im Berührungspunkt.Deposits of metal or metal oxide on the burnout disc are removed by the brush 7. The brush 7 rotates in direction B, that is, against the direction of travel of the burn-out disk at the point of contact.
