  Verfahren zum Unsichtbarmachen der sogenannten Regenstreifen auf Films. 



   Die Erfindung betrifft ein Verfahren und ein Mittel, um die sogenannten Regenstreifen auf Films ganz oder im wesentlichen für die Dauer der   Vorführung   unsichtbar zu machen. 



   Die bisher zu diesem Zweck vorgeschlagenen Mittel, wie insbesondere fette Öle, lassen zwar eine zufriedenstellende technische Wirkung erzielen, es zeigen sich jedoch bei ihrem Gebrauch gewisse Missstände, insbesondere dadurch, dass die dauernd mit den genannten Fettstoffen in Berührung bleibenden Films allmählich verstauben und verschmieren. dass sie infolgedessen wiederholt gereinigt werden müssen und dass der Abrollmechamismus

 fettigen Ölbestandteile starke Flecken hinterliessen, wodurch die   Beschaffenheit   der Filmbilder nicht unwesentlich beeinträchtigt wurde. 



   Gemäss der Erfindung wird die Aufgabe, die Regenstreifen für die Dauer der Vor-

   Durch die Wahl einer leicht verdunstenden Flüssigkeit wird bezweckt, zu verhüten, dass auf dem   vorgeführten Film   nach der Projektion beim   Wiederaufspulen   auf der

  Process for making the so-called rain streaks on film invisible.



   The invention relates to a method and a means for making the so-called rain streaks on film completely or essentially invisible for the duration of the presentation.



   The agents proposed so far for this purpose, such as fatty oils in particular, allow a satisfactory technical effect to be achieved, but there are certain deficiencies in their use, in particular because the film that is permanently in contact with the fatty substances mentioned gradually becomes dusty and smeared. that as a result they have to be cleaned repeatedly and that the unwinding mechanism

 greasy oil components left strong stains, which significantly impaired the quality of the film images.



   According to the invention, the task is to keep the rain strips for the duration of the

   By choosing a liquid that evaporates easily, the aim is to prevent the film being shown from being rewound on the after projection

    PATENT CLAIMS:
1. A method for making the so-called Kegen strips on film invisible, characterized in that the film evaporates with an Ipicht during the presentation.
