A method of providing a plurality of filled product bags of sterile fluid includes positioning a bag assembly onto a filling machine. The bag assembly includes a tube, a filter assembly, bladders, and stems. A stem is attached to a bladder, forms a fluid passageway, fluidly connects to the tube, and provides fluid communication into the bladders. The method includes fluidly coupling an inlet of the filter assembly to a connection line in fluid communication with a fluid source, and filling the bag assembly with a fluid. Filling the bag assembly includes passing the fluid through the filter assembly, the fluid passageway, and into the bladder. The method includes sealing the fluid passageway at a location between the tube and the bladders. The method includes cutting the stem to form a partially filled product bag having the sealed passageway. The method includes performing an integrity test on the filter assembly.

A device for packaging elongated items such as firewood pieces is described herein. The device includes: an elevated structure having an upper platform for receiving the elongated items from a separate conveyor; a diverter located on or above the platform for changing the direction of movement of the elongated items; and one or more elevator shafts having open bottoms. The elevator shafts are located adjacent to the platform and configured for receiving the elongated items after contact with the diverter and for holding the elongated items on support structures while a stack of elongated items is formed. The release of the stack of elongated items from the elevator shafts occurs via the open bottoms of the elevator shafts.

A dosing apparatus for a machine for producing unit dose articles including first and second dosing units each having: a nozzle support body carrying a plurality of nozzles, and a movement control unit configured for moving the respective nozzle support body along a closed-loop path, wherein the movement control units of the first and second dosing units are configured for moving the respective nozzle support bodies independently of each other along the closed-loop path.
