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).
