ABSTRACT:
A vacuum chamber has a port communicating with the interior of the chamber, and a blower and ducting for selectively establishing a vacuum within the chamber. A partially completed bag of seamed panel construction is placed with the port extending into the bag. When vacuum is applied, the bag is passed through the port, being thereby turned inside out. A pneumatically-controlled door enables access to the chamber for removal of the bag.
