Abstract
An apparatus for evacuating and sealing rectangular packages includes a turntable, a plurality of vacuum hoods arranged circumferentially on the turntable and having an open position in which a package to be evacuated and sealed is received and a sealed, closed position. There is provided a package-engaging surface on each hood on its inside and an abutting mechanism arranged on the turntable below each vacuum hood. Each abutting mechanism also has a package-engaging surface. The abutting mechanism is arranged for radially outward movement for displacing, with its package-engaging surface, a package towards the package-engaging surface of the vacuum hood. In the closed position of the vacuum hood the package thereunder is engaged at opposite sides by the two surfaces.
