FilmrolleFilm reel

Neuerdings haben sich photographische Aufnahmeapparate (Kameras, wie sie unter dem als Warenzeichen gesetzlich geschützten Namen Leica bekannt sind) eingeführt, welche einen kinematographischen Filmstreifen als Aufnahmematerial benutzen. Diese Filmstreifen werden zum Teil auf Spulen in gewissen Längen, welche die Aufnahmefähigkeit einer Kassette nicht übersteigen dürfen, aufgerollt und mit einem Schutzpapierstreifen gegen die Einwirkung schädlichen Lichtes gesichert (Tageslichtspulen), zum Teil werden sie in Rollen beliebiger Länge bezogen und nach Bedarf in Gebrauchslängen von diesen Rollen abgeschnitten (Dunkellichtrollen).Recently, photographic recording devices (cameras, as they are under the are known as trademarks legally protected names Leica), which a cinematographic film strips as recording material use. These film strips are partly on spools of certain lengths, which must not exceed the capacity of a cassette, rolled up and covered with a strip of protective paper secured against the effects of harmful light (daylight coils), some of them are available in rolls of any length and cut from these rolls in usable lengths as required (dark-light rolls).

Um bei letzteren den Filmstreifen in den Transportmechanismus einzuführen, muß der Anfang des Filmstreifens in einer Form zugeschnitten werden, welche in Abb. 1 dargestellt ist.To put the film strip into the transport mechanism for the latter the beginning of the filmstrip must be cut in a shape shown in FIG.

Bei den in beliebigen Längen zugeschnittenen Rollen (Dunkellichtrolle) ist diese Formgebung mit erheblichen Schwierigkeiten verknüpft, weil der Verarbeiter natürlich nicht über die erforderlichen Hilfsmittel zur Längenmessung und über die geeigneten Schneidewerkzeuge verfügt.With the rolls cut to any length (dark-light roll) this shape is associated with considerable difficulties because the processor naturally does not have the necessary Aids for length measurement and has the appropriate cutting tools.

Die Schwierigkeiten bei Verwendung der 2g Dunkellichtrollen werden behoben, wenn man die Formgebung in entsprechenden Abständen bereits in der Rolle vorsieht, so daß lediglich eine schmale Verbindung A-B getrennt werden muß (Abb. 2).The difficulties when using the 2 g dark-light rollers are eliminated if the shape is already provided in the roller at appropriate intervals, so that only a narrow connection AB has to be separated (Fig. 2).

Claims (1)

Patentanspruch:Claim: Filmrolle, die in Stücke von bestimmter Länge zerschnitten werden soll, deren Enden für die Einführung in den Transportmechanismus eine bestimmte Form haben müssen, dadurch gekennzeichnet, daß der Film in den gewünschten Abständen bis auf eine kurze, etwa die Mitte der Bahn einnehmende Strecke quer durchgeschnitten und ferner so zugeschnitten ist, daß nach dem späteren Durchschneiden dieser Querstrecke [A-B) das eine Ende eine stumpfe Spitze bildet, während an dem änderen Ende eine Schnittlinie, etwa in der Mitte der Bahn beginnend, zunächst geradlinig und schwach mit der einen Seitenkante konvergierend und dann im Bogen bis zu dieser Kante verläuft.Roll of film which is to be cut into pieces of a certain length, the ends of which must have a certain shape for introduction into the transport mechanism, characterized in that the film is cut transversely at the desired intervals up to a short distance approximately in the middle of the web and is also cut so that after later cutting through this transverse section [AB) one end forms a blunt point, while at the other end a cutting line, beginning approximately in the middle of the path, initially straight and weakly converging with one side edge and then runs in a curve up to this edge.
