ABSTRACT:
A wrap suspended in air by creating a cushion of air above and below the wrap is inserted into an envelope, formed by a clear plastic cover and the body of a clamshell, by propelling the wrap and the cushion of air into the envelope. The clear plastic cover is initially moved away from the body of the clamshell to enlarge the envelope opening so the wrap can be inserted. Video cassettes or other articles may be located within the clamshell by a conveyor system substantially contemporaneously with the insertion of the wrap.
