Abstract
When filling flexible bags with a specified quantity of material, the uppermost one of the bags is opened at the mouth thereof and a spatular element is inserted into the bag while streams of gas are discharged from the surface of the element. Then, a vacuum suction force is applied to the surface of the spatular element to cause the bag to be sucked to that surface so that the bag, together with the element, is moved into a recessed wall of a stand frame. The bag is inflated in the recessed wall by discharging jets of gas from the surface of the spatular element into the bag, and simultaneously the bag is sucked to the inner surface of the recessed wall under a vacuum suction force while being held in opened condition. Subsequently, the specified quantity of material is filled into the bag. In this way, each flexible bag is moved to the stand frame while being accurately sucked to and kept in the spatular element. The bag can also be accurately held in opened condition while being sucked to the inner surface of the recessed wall. Thus, any desired material can be filled into the flexible bag without any filling error.
