Abstract: Apparatus for supplying valved sacks or bags to filling nozzles is disclosed, including a first conveyor for transporting a sack to a waiting position spaced from the filling nozzle a distance at least equal to the width of the sack, and a second conveyor for transporting the sack in a suspended valve-open condition to the filling nozzle. A releasable gripping device associated with the second conveyor engages the sack adjacent the bottom of the valve means, thereby to open the same, which gripping device includes a pair of spaced opposed sheet metal plates.

Abstract: An arrangement for closing valves of valve bags filled by a filling machine comprises at least one conveyor arranged to transport valve bags in flatly lying position and a unit for closing the valves of the valve bags and associated with the conveyor. At least one abutment is located above the conveyor and is turnable outwardly beyond a movement region of the valve bags. Two first parallel spaced plates and two second parallel spaced plates are arranged above the conveyor and are movable transversely to a transporting direction of the latter to provide, respectively, for orienting the filled valve bags and for preparing the filled valve bags for closing of their valves.
