ABSTRACT:
Apparatus for attaching adhesive-coated bands to damaged portions of photographic films or the like has a suction drum which attracts the leader of an adhesive tape and cooperates with a heated wire to sever the leader and to thus form a succession of adhesive-coated bands which are attached to damaged portions of films. The attachment of bands can take place by moving the damaged portion of a film against the drum and/or by moving the drum against the damaged portion of the film. If the film is to be coated at both sides, it is caused to pass between two drums which can be located directly opposite each other or are spaced apart, as considered in the direction of lengthwise movement of the film.
