To completely automate a film connecting work so that there is no deviation in the width direction between a film on a supply side reel and a film on a waiting side reel when the film on the supply side is used up.

In a packaging film feed device in which reels R1, R2 are provided on a pair of supports frames which are longitudinally movable in a direction orthogonal to a film moving direction relative to an automatic packaging machine, one of the reels is on the supply side and the other reel is on the waiting side, and the film F on the supply side and the film F' on the waiting side are alternately connected when the film on the supply side is used up, the support frames are provided with a pair of film connecting rolls rotatable opposite to each other between the reels, the film on the supply side is passed therebetween, and a tip part of the film on the waiting side is temporarily stopped by attaching a pressure sensitive adhesive double coated tape to a roll press part on its side. By detecting that the film on the supply side is used up, the rolls are rotated, and the films are connected to each other through the tape at the pressing part.
