Abstract: When replacing film rolls, a film holding mechanism fixedly holds a film of a pre-replacement film roll. At the same time, a film suction mechanism holds a film by suction. A film storing mechanism pulls the end of the film up to the film suction mechanism. Furthermore, the end of the film that is held by the film suction mechanism by suction and the head of the film of the post-replacement film roll are joined using an adhesive tape. Also, once it is detected based on the output from the load cell that the film has been entirely unrolled, the control device stops the operations of an items supply portion and motor. Accordingly, the items that have been supplied to a bag-manufacturing and packaging portion from the items supply portion at the time the items supply portion is stopped are packaged using film stored in a film storing mechanism. Then, the control device stops the operation of the bag-manufacturing and packaging portion.
