ABSTRACT:
A device for feeding a film from a patrone in a camera, in which the film is fed by an endless caterpillar belt having pawls for engaging with film perforations. The caterpillar belt is positioned in a camera so as to match the film perforations between two film guides of the camera and is extended parallel to the film feeding direction. The caterpillar belt is driven by a set of a driving pulley and a driven pulley. The section of the pawls, taken along the film plane, is shaped to have a circular arc contour so as to contact only with the vicinity of the central portion of each film perforation.
