  • Patent number: 4156334
    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movable member has suction heads turned toward the first movable member and is adapted to grip the rear face of a bag withdrawn by the first from the magazine so that separation of the two members effects an opening of the bag.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.

  • Patent number: 4033096
    Abstract: An apparatus for opening bags of the synthetic-resin foil type in which the bags are successively drawn from a horizontal magazine by a movable suction member displaceable horizontally, are brought into the proximity of a further suction member raised between the bag and the magazine and are then drawn open between the suction members. The bag is then laterally engaged by a pair of guide-pincer members and guided thereby onto the clamping pincers of a carriage to be shifted to a filling station along the transport path of this carriage.
