Abstract

When filling a valve bag (1) with dust-producing or hazardous material through a filling valve (5) arranged in a corner of the bag, use is made of a ventilating valve (7) for evacuation of air, arranged in the opposite corner of the bag and having a transversely folded filtering sheet (9), whose transverse fold faces outwards such that during evacuation of air the ventilating valve (7) opens in U-shape from the inside. After the filling operation, the filling valve (5) is directly sealed, whereupon final evacuation of air, for instance by mangling, occurs through the ventilating valve. <IMAGE>
