Rotary packaging machine and method for filling open-mouth bags with multiple filling units disposed over the circumference and rotating along, each of which having a filling spout with a bottom filling opening, wherein the open-mouth bags can be appended by way of a motion oriented upwardly relative to the filling spout. An air scoop section is connected to a head end of the shell and forms two air inlets on opposite sides of the handgrip. The two connecting members 31 and 32 are arranged to sandwich upper case 11 and lower case 21 from the outside. A field emitter device can be manufactured with such a film. The inner concentric circle is centered about the center point and represents a horizon plane that is perpendicular to a zenith-nadir line that passes through the zenith, the ego center, and the nadir. In one form the method and system of the present invention relate to anchoring fiber end points adjacent or against the field plate of a telescope.
