  • Patent number: 4385670
    Abstract: A method for measuring out and filling of pourable goods into packaging containers and an apparatus which functions according to this method are proposed. In order to attain high filling output especially in the case of voluminous goods, or goods having a low specific weight, a feeding apparatus for the packaging containers is assigned one after another a plurality of weighing devices each having one dispensing device. The weight values of the first partial quantities measured out and filled into the packaging containers are added up in a computer (S I-S II, .SIGMA.I+II-.SIGMA.I+II+III), which directs the last dispensing device to furnish the remaining deficient quantity.
