    (54) Apparatus for continuously supplying film


    (57) An apparatus for continuously supplying a film-type material has a holding mechanism (24) for holding a new film-type material (16) which is to be connected to a preceding film-type material (5) running at a predetermined speed, a synchronizing mechanism (25) for accelerating the holding mechanism (24) to the predetermined speed at which the preceding film-type material (5) is running thereby synchronizing the movement of the new film-type material (16) with the running of the preceding film-type material (5); and a connecting mechanism (26) for connecting the leading end of the new film-type material (16) to the preceding film-type material (5) running at the predetermined speed, whereby the new film-type material (16) is connected to the preceding film-type material (5) without requiring stopping the operation of the apparatus.
