Abstract
A vacuum packaging system includes a series of vacuum chambers that are carried by a movable combination support member and vacuum manifold, which defines an interior connected to a vacuum source. The vacuum chambers are in communication with the interior of the combination support member and vacuum manifold, through vacuum valves carried by the combination support member and vacuum manifold and conduits that extend between the vacuum valves and the vacuum chambers. The combination support member and vacuum manifold is movable between a lowered position and a raised position, to move the vacuum chambers into and out of engagement with platens that support packages located below the vacuum chambers. The vacuum chambers and platens are movable in an upstream to downstream direction, to advance the packages while the packages are being evacuated by the vacuum chambers.
