PURPOSE: To retain a charging speed and capacity by fitting only one of strips to a film, turning upward the other strip and advancing forward a connected fastener strip sideways across the film. CONSTITUTION: A fastener strip assembly body 16 is fitted to the inside face of a film 10 when it is fed forward to molding, charging, and sealing machines. Although the fastener strip may be directly laid on the film 10, it is preferably fed in the side across the upper face of the film 10 at right angles against the edge in the longitudinal direction of the film 10, or at right angles against the longitudinal molding axial line of the film 10. One profile strip is provided with a grove and the other is provided with a profile having a shape stationarily received in the groove. The rib and the profile strip with a groove are engaged with each other or connected to each other before they are fed across the film. In this way, the charging speed and capacity can be favorably retained. |
