MANUFACTURE AND DEVICE FOR BAG WITH JAW DEVICE

摘要

PURPOSE:To improve productivity by performing favorably and continuously adhesion of jaw devices by a method wherein a base material film and a tape with the jaw devices superposed upon each other are run continuously, welded with ultrasonic energy and a bag is manufactured after manufacture of a film with the jaw device. CONSTITUTION:A base material film 1 is sent through a guide roller 9 from a base material film supply roll 2. The same and a tape 3 with jaw device from a tape with the jaw device supply roll 4 are superposed upon each other on the way by pressurizing them by passing through between a pair of guide rollers 10, 11 and that of the next guide rollers 12, 13 which are facing on each other. They are run continuously and passed through between an ultrasonic horn 5 and anvil 8 confronted with the horn 5. A film 19 with the jaw device is obtained by performing welding between the base material film 1 and the tape 3 with the jaw device with ultrasonic energy oscillated through an ultrasonic oscillator 6 at a position where the ultrasonic horn 5 is provided. The film 19 with the jaw device is bent at the center and a male jaw device 14 and female jaw device 15 are engaged with each other. Then a bag with jaw device is manufactured by sealing the side meeting at right angles with a sending direction according to a conventional way.
