るものである。 That is, in the present invention, a synthetic resin bag is placed on a conveyor and conveyed in one pitch motion so that the sealed upper end is at the hanging header attachment position, and then a synthetic resin header sheet is placed on the conveyor. The end of the conveyor is viewed from a direction perpendicular to the flow of the conveyor.
At the same time, it is sent out to the front so that it overlaps approximately the center of the upper end of the bag, and is thermally welded to the bag,
After cutting the header sheet and providing a hanging header having a desired width at the upper end of the bag body, this header is moved to the punching position using the one-pitch movement to form the header into the desired shape. The present invention provides an automatic method for attaching a hanging fixture characterized by punching.
