ABSTRACT:
An apparatus for packaging articles in deaerated condition. A belt-like film is tubulated to enclose a plurality of articles transported in a longitudinally aligned fashion. The articles and the film are transported together in integral relation while the air in the tubular film is evacuated by a pipe nozzle inserted in the film tube. The pipe nozzle is connected to a vacuum source via a connecting pipe. Usually, the interior of the tubular film is kept in a suitable negative pressure condition by suction through a tube bypassing a normally closed valve disposed on the connecting pipe. The valve is impulsively opened immediately before seal bars press the film from opposite sides so that the air in the film is instantly discharged.
