  • Patent number: 7063111
    Abstract: A method of filling a bag with pourable, especially powdery material, by means of a dispensing device with a vertical filling pipe which can be introduced into the bag and which comprises flanging-on means at its upper end and a closing device at its lower end, wherein prior to or during the filling operation, air is extracted from the material above the closing device via the inside of the filling pipe.

  • Patent number: 6810921
    Abstract: A method of filling containers, especially bags, with bulk material by a feeding funnel and a filler pipe. The filler pipe adjoins the lower end of the feeding funnel. An axially displaceable and rotatable conveying unit is arranged co-axially within the filler pipe. An axially displaceable and rotatable closing element is firmly connected to the lower end of the conveying unit. The bulk material, while being conveyed by the conveying unit in the filler pipe, is simultaneously mechanically agitated in the filling funnel, or simultaneously mechanically conveyed in the filling funnel towards the filler pipe.

  • Patent number: 6786367
    Abstract: The present invention provides a filling sleeve which allows containers with a rectangular or square cross-section, especially bags with deep side folds, to be filled advantageously in that they are given a stable shape. The objective is achieved by means of a filling sleeve which is characterized in that, in the exit cross-section, a central region is provided with inserts and four separate exit apertures are kept open in the corners of the square or rectangular cross-section. In this way, the filling material flowing through the substantially completely open and normally undivided entrance cross-section of the filling sleeve is divided into four individual streams which are associated with the corners of the exit cross-section. Thus, while being filled, the bags are initially stabilized from the corners, as a result of which a certain tension remains in the walls between the corners, so that the walls cannot bulge out when the level of the filling material rises.

  • Patent number: 6237815
    Abstract: A dispensing device for pourable, especially powdery material, has a charging chute, a vertical filling pipe adjoining the lower end of the charging chute, and a closing cone arranged at the lower end of the filling pipe. The closing cone is displaceable in the longitudinal direction of the filling pipe by a shaft. The closing cone, in its open position, provides an annular gap at the lower end of the filling pipe. In its closed position, the closing cone rests against an annular face or annular edge at the lower end of the filling pipe. The closing cone, on an upwardly pointing conical face, includes blades with a desired slope. The closing cone is rotatingly drivable to convey material through the annular gap by the blades.
