Abstract: Described is a filling apparatus for filling packaging means with quantitatively controllable amounts of a flow substance, having a pump piston (54) which is movable in a cylinder (50), wherein the feed end and the discharge end of the pump chamber (9) are respectively closed by valves (4, 5) and, to avoid foaming, the discharge end at least partially dips into the upwardly open packaging means (10). Also provided is a drive means (31, 37) with cam member (28).
Abstract: A method is disclosed for fabricating packing containers comprised of a heat-shrinkable material. A web or blank of the material is heated on one side to an extent such that the material acquires a tendency to assume a tubular shape. Overlapping longitudinal ends of the web or blanks are heat and pressure sealed to form a tubular member. The ends of the tubular member are folded inwardly under the effect of heat to form flange-like portions to which end plates may be attached to form the packing container.
Abstract: The packing machine of the invention molds a first material web into a line of connected U-shaped sections; joins a second material web to the first material web and seals them together; fills the resulting cavities with an intended filling material; seals the filled cavities, and finally separates the line into individual filled packages.
