ABSTRACT:
An apparatus for the opening of flat bags, particularly of synthetic resin, originally in a stack, comprises a first movable device turned toward the stack which is oriented horizontally with the bags lying vertically and carrying suction heads adapted to draw a bag of the stack away from a magazine containing same. A second movable member has suction heads turned toward the first movable member and is adapted to grip the rear face of a bag withdrawn by the first from the magazine so that separation of the two members effects an opening of the bag. A third device is shiftable vertically to urge the open bags between the pincers of a transfer chain which carries the open bag to a filling station.
