  Filmwechselpackung. 



   Die Erfindung besteht in einer Verbesserung an Filmwechselpackungen. Es ist ein bekannter Übelstand dieser Packungen, dass beim Wechseln, d h. beim Entfernen des jeweilig vordersten der auf   lichtundurchlässigen   Trägern befestigten   Filmblätter   nach   geschehener   Belichtung oder beim Bewegen von Schiebern oder Deckblättern, die vorzeitige Belichtung verhindern sollen, oft die lichtempfindliche Schicht, wenigstens an ihrer Oberfläche, verletzt wird. Es soll deshalb nach vorliegender Erfindung das Filmblatt so auf seinem Träger angebracht werden, dass es diesem die lichtempfindliche Schicht zukehrt.

   Dip Lage des Negativbildes auf dem Filmblatt weicht dann allerdings von der bisherigen ab, so dass beim Kopieren die durchsichtige Unterlage, die mit der lichtempfindlichen Schicht zusammen das Filmblatt bildet, als eine Zwischenschicht das Negativbild von dem zu er- 
 EMI1.1 
 Unterlage nicht wesentlich dicker ist als die jetzt gebräuchlichen. 



   Für Zeitaufnahmen lässt sich aus der umgekehrten Lage   der Filmblätter noch ein   weiterer Vorteil dadurch gewinnen, dass man die durchsichtige Unterlage der lichtempfind- 
 EMI1.2 
 schlechterung dos Bildes   herbeiführen   sollen. mit grosser Sorgfalt hergestellt sein und sind dann entsprechend teuer. 



   PATENT-ANSPRÜCHE   :   
1.   Filmwechselpackung,   dadurch gekennzeichnet, dass jedes Filmblatt seinem Träger die lichtempfindliche Schicht zuwendet, damit diese Schicht beim Wechseln nicht   beschädigt   werden kann. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Film change pack.



   The invention consists in an improvement in interchangeable film packages. It is a known drawback of these packs that when changing, i. E. when removing the foremost of the film sheets attached to opaque carriers after exposure has taken place or when moving slides or cover sheets that are intended to prevent premature exposure, the light-sensitive layer is often damaged, at least on its surface. According to the present invention, the film sheet should therefore be attached to its support in such a way that the light-sensitive layer faces it.

   Dip position of the negative image on the film sheet then differs from the previous one, so that when copying the transparent base that forms the film sheet together with the light-sensitive layer, as an intermediate layer, the negative image of the
 EMI1.1
 The base is not much thicker than what is now in use.



   Another advantage can be gained from the reversed position of the film sheets for time recordings in that the transparent base of the light-sensitive
 EMI1.2
 to cause deterioration of the picture. be manufactured with great care and are then correspondingly expensive.



   PATENT CLAIMS:
1. Film change pack, characterized in that each sheet of film turns the light-sensitive layer towards its carrier so that this layer cannot be damaged when changing.
