<p>The invention relates to a process for accurately filling bags or containers with a flexible filling sleeve with a dust forming product. The process uses a filling spout (4) having an outer wall (7), said spout comprising a material supply pipe (5) and a dust extraction pipe (11), and comprising the steps of: fitting the filling opening (2) of said sleeve over said outer wall (7) of said spout (4), thereby defining an air gap (16) between said sleeve (3) and said outer wall (7), filling the container (1) through the supply pipe (5) with said powdery material, whilst simultaneously removing air from the bag through said dust extraction pipe (11) so as to create a Bernoulli effect in said air gap (16) pushing a portion of said sleeve (3) towards said outer wall (7).</p> |
