Während des Umganges um die Trommel erfolgt die Belichtung entweder durch natürliches Licht oder durch eine künstliche Lichtquelle, wie bei dem dargestellten Beispiel angenommen.
Diese Lichtquelle, etwa eine oder mehrere elektrische Gobenlampen, sind bei h angeordnet.
Das belichtete Papier oder dergl. wird bei i abgenommen, aufgerollt oder abgeschnitten und die Zeichnung fortgenommen. Es könnte aber auch durch eine an der Trommel a anliegende und sich mit dieser drehende Rolle selbttätig aufgewickelt werden.
Die Fig. 3 und 4 zeigen in zwei verschiedenen Ansichten einen ebenfalls mit einem endlosen durchsichtigen Bande arbeitenden Apparat für grössere Leistungen.
Dieser Apparat besitzt zwei Trommeln a und al, um die das endlose durchsichtige Band b herumläuft. Die Trommeln a, a' und das Band b werden bei dem dargestellten Ausführungsbeispiel durch einen Elektromotor i angetrieben. Durch Stufenscheiben k, k' kann die Bewegung auf die für die Belichtung not wendige Geschwindigkeit genau eingestellt werden.

During the handling of the drum, the exposure takes place either by natural light or by an artificial light source, as assumed in the example shown.
These light sources, such as one or more electric gob lamps, are located at h.
The exposed paper or the like is removed, rolled up or cut off at i and the drawing is removed. But it could also be automatically wound up by a roller resting against the drum a and rotating with it.
3 and 4 show, in two different views, an apparatus for greater capacities which also works with an endless transparent band.
This apparatus has two drums a and a1 around which the endless transparent belt b passes. The drums a, a 'and the belt b are driven by an electric motor i in the illustrated embodiment. By means of stepped disks k, k ', the movement can be precisely adjusted to the speed required for exposure.
