Abstract: A packaging apparatus for placing a fixed quantity of powdery and/or granular material in bags has one bag-supplying device and two filling and weighing devices mounted in a line on the same base, and two distribution/conveyance devices, which distribute empty bags and convey them to the filling devices between said bag-supplying device and said filling devices. There is also a sealing device which seals the top edge of each bag filled with a weighed quantity of material. All the devices are arranged generally in a straight line and can continuously supply and open empty bags, fill them with material, and seal said bags without any pause.
