Device and method for packaging flowable materials

Method for filling flowable materials into flexible, empty open-mouth bags comprising an apparatus with a stationary part and a movable part wherein the movable part is provided with multiple filling stations traveling along and a retaining device is fastened to the movable part at each of the filling stations, and wherein multiple handling stations are provided that are distributed at the stationary part, wherein at least one handling station acting as a takeover station successively takes over empty open-mouth bags and at least one handling station at least partially fills the bags, and wherein at least one handling station is provided with a weighing unit, characterized in that a bag receiving unit is fastened to each of the retaining devices to receive a bag, wherein the bag receiving unit receives and guides the bag at the takeover station,

• and that the movable part successively takes the bag receiving units to the handling stations, and that the retaining device provided at the handling station equipped with the weighing unit temporarily decouples the bag receiving unit being handled from force transmission with respect to the retaining device so that a separate weighing of the bag receiving unit with the bag can be carried out.
