PURPOSE: To shorten the operating time when one bag is laid by sucking to hold the opening side peripheral edge of the bag supplied to a bag opening position by each sucking roll, and blowing the air into the bag opened and held by the roll to be inserted into a box. CONSTITUTION: A bag opening mechanism 4 is driven to bring the sucking holes of sucking rolls 45 into close contact with the lower end of a film raw fabric (f) fed to the opening position directly under a separate position at the opening side, and the opening side lower end of the fabric (f) is sucked to be held. Then, the opening side lower end of the fabric (f) sandwiched between the rolls 45 and each bag pressing plate is opened in the longitudinal direction. Simultaneously, the air discharged from injection nozzles 52 is sprayed to the longitudinal upper surface of a packaging bag opened and held by the rolls 45 and the pressing plate to be forcibly inserted into a corrugated fiberboard case B. |
