ABSTRACT:
The invention relates to an apparatus for forming, filling and sealing bag-type packages. For certain filling products it is advantageous to "strip" or flatten the bag-type package prior to sealing, i.e. to ensure that the bag is volumetrically displaced. As a result all bag-type packages are tightly filled despite varying specific weight of the filling product. This object of the invention is achieved by return conveyance or feed of the bag hose or tube and passage of the latter through a constrictive location. An advantage of the apparatus resides in the possibility of achieving high production speeds by virtue of small moved masses.
