The following quote was obtained by the news editors from the background information supplied by theinventors: “Various filling devices are known from prior art for filling flexible containers, for example valvebags, with powdered filling material. The latter convey the filling material using pressure or by applying avacuum in a corresponding vacuum chamber. After filling is complete, the container is sealed in the areaof a valve, which in valve bags comprises a short, tubular end piece of the bag, via welding, folding or thelike, so as to completely surround the filling material, and thereby protect it against outside influences.The valve bag is subsequently relayed to continued processing or transport.
