Abstract

PURPOSE: To obtain a continuous film sheet to be used for a continuous filling and packaging by means of an automatic filling-packaging device, by a method wherein a faulty portion is cut off while the film is extended, and the two cut portions overlapped together are welded by means of an ultrasonic sealer to be flatened to the same level as that of the film surface.
CONSTITUTION: An extended film 10 has already been checked after printing process is complete, and detected faults such as wrong printings, damages, dust adhesion, etc., are marked. When the marking is detected, feeding of the film is suspended, and the faulty portion is removed by cutting 20. The cutting 20 is performed over the full length in the longitudinal direction of the film. Two films so cut are then overlapped, and the overlapped portion 22 is welded in a line by means of an ultrasonic sealer. A linear welded portion 26 is then ultrasonic-sealed again, and the convex portion 26 is flattened by melting so that the convex is made even to the same level as that of the film surface.
