ABSTRACT OF THE DISCLOSURE An apparatus for spreading open flattened bags has a first air-pervious endless belt having a working flight provided with a working face and an opposite, reverse face; and a second air-pervious endless belt having a working flight provided with a working face and an opposite, reverse face. The working flights of the first and second belts are divergent at an acute angle in the bag conveying direction. There is further provided a suction device generating a vacuum for urging a gas to flow across the working flights in a direction from the working face to the reverse face of each working flight, whereby each bag introduced between the working flights adheres, with opposite bag panels, to the working faces of the working flights and is forwarded thereby in the conveying direction, while being gradually spread open. - 17 -
