Abstract
For automatically suspending large sacks successively from a filling device, each flattened sack is folded at least once onto itself. Every sack is in turn brought up to stops on a table and scanned for alignment by photocells. The mouth of the sack is pulled open by suckers, transferred to gripper mechanisms which are carried by swing arms and provided with hinged grippers co-operating with wedges inserted in the open mouth, and the sack is then swung from the table to the filling device where it is pushed onto a funnel.
