发明名称 Device for forming partitioned film packages
摘要 A process for producing partitioned packages by which a first film is formed into an elongated inner tube and a second film is formed into an elongated outer tube surrounding the inner tube. Reactive components are filled into the inner and outer tubes as the tubes are formed to maintain the reactive components separate from each other. Only the outer tube is actively engaged to advance the tube longitudinally. Frictional forces from the advancing outer tube are applied to the component within the outer tube and, in turn, are applied to the inner tube thereby advancing the inner tube at a rate substantially the same as the outer tube.
