Abstract
Apparatus for splicing successive exposed photographic films end-to-end by means of uniting bands one side of which is coated with hotmelt has a ribbon which is severed at regular intervals at the splicing station to yield a succession of uniting bands. Each band is caused to overlie the ends of films at the splicing station and is thereupon pressed against the films by two heated rams which move toward each other as soon as a fresh band is separated from the ribbon. The ribbon is retracted from the splicing station immediately upon severing to avoid the flow of hotmelt thereon as a result of heating action of the rams.
