Summary:PURPOSE:To permit an invariably uniform supply of air and eliminate the need for the inspection process of the air amount, by filling a predetermined amount of products in a bag, sealing the same while retaining the bag to be inflated with the air so as to conform to a die and cutting off the sealed part from the bag for the successive bagging operation. CONSTITUTION:A bag 1 is set in a die 100 having a predetermined shape, products 2 and air 3 are filled in the bag from a feed nozzle 15 and the bag 1 is inflated conforming to the inner shape of the die 100. An opening at the top of the bag is sealed by a heat sealing devices 40 and 45 while supplying the air 3 and a central sealed part 4 is cut off from the bag by a cutter 50. The sealing devices 40 and 45, the cutter 50 and the die 100 are moved back and the products 1 are transferred on a conveyor. The succeeding bag 1' is set in the die 100 and the same processing is repeated. This method permits the bag 1 to be sealed in a predetermined inflating condition with no leakage of the air 3 and inflated in conformance with the shape of the die 100, eliminat ing the need for a fine adjustment of the air pressure and flow and facilitating the control and operation of bagging.
