Film feeding apparatus

A film feeding apparatus comprising a body which has a first film roll for feeding a first film with positioning registered marks and an auxiliary film roll for feeding a second film with positioning registered marks, and means for feeding the first film to a working machine through a conveying path, wherein said apparatus comprises a first sensor on the conveying path for detecting the end of the first film and a second sensor on the conveying path for detecting the positioning registered marks on the first film that are located adjacent to the terminal end of the first film, a film holder for holding the beginning end of the second film, said film holder comprising a pair of side plates which has therebetween a pressing plate with an intermediate V-shaped recess, said pressing plate being provided, in the V-shaped recess, with an elongated hole having a length corresponding to the width of the first and second films, said pressing plate having an elastic engaging means for holding the second film, a film pressing member comprising a rubber plate actuated by a pneumatic cylinder for pressing the first film against the second film, said film pressing member further including a leaf spring which elastically connects the rubber plate to the pneumatic cylinder and which is made of two bent leaves interconnected in the form of an ellipse, so that the leaf spring can be elastically deformed when the rubber plate comes into press contact with the film holder by the operation of the pneumatic cylinder, said film holder and said film pressing member being located on opposite sides of the conveying path so that the film pressing member comes away from and close to the film holder, the first positioning registered marks of the second film being spaced from the beginning end thereof at a predetermined distance, said beginning end of the second film being provided with an adhesive tape which is partially adhered thereto, a cutter located in the vicinity of the film holder for cutting the first film in order to separate the first film from the first film roll, said pneumatic cylinder capable of actuating said film holder and/or said film pressing member to cause them to come close to each other in order to connect the first film to the second film by means of the adhesive tape at the beginning end of the second film and actuating the cutter to cut the first film by thrusting the cutter into the first film and entering the V-shaped recess of the film holder, wherein the first sensor detects the end of the first film and then the second sensor detects the first positioning registered marks, and timer means for controlling the time at which the cutter begins operating subsequent to the detection of the first positioning registered marks by the second sensor.
