Abstract
A vacuum packing apparatus for vacuum packing objects into flexible bags. The apparatus has first and second gears rotatable around a pair of spaced apart vertical axes and an endless chain which is engaged with the gears. The first gear has a plurality of chambers spaced at intervals from one another, and the chain carries a plurality of lids for hermetically sealing the chambers. Each lid includes a pair of clippers for hanging the bags in suspension with the bag openings oriented upwardly. A bag feed unit feeds bags to the clippers and a hopper unit feeds objects into the bags while the bags are supported in suspension by the clippers. Each bag, while being supported in suspension by a pair of clippers on a lid, is positioned into a chamber by the positioning of the lid over the chamber. After a vacuum is formed in the chamber, and hence in each bag, the bags are sealed to provide a vacuum packed bag.
