Abstract: An installation for manufacturing and filling multiple-cavity bags made from a sheet of plastic material, includes a forming column for forming a multiple-cavity bag, with the column being divided into three zones, a first zone forming a single tubular sleeve by a longitudinal seal of sheet edges thereof, a second zone for forming a bottom and cavities of the bag, and a third zone for filling and closing the bag and moving the closed bag away from the column, and a film feed mechanism for feeding plastic film to the forming column.

Abstract: A process for continuously manufacturing and filling multiple cavity bags, includes the steps of forming a wrapping into a tubular sleeve shape from at least one sheet of plastic material, feeding the forming plastic sleeve along a forming column, sealing the wrapping along a first longitudinal seal to form a sleeve, feeding the sleeve along two cores, sealing bottom and central parts of the sleeve to form a partially sealed bag with two separate cavities therein, filling each of the cavities formed in the partially sealed bag through filling mouths for the cavities, closing the filling mouths to form a closed bag, cutting off the closed bag from the previous bag, and removing the closed bag.
