Summary:PURPOSE:To eliminate the deviation of an object to be packaged in a packaging bag and after that make perform a seal check accurately by providing a flattening means which has a plurality of rotors with protuberance on the upward tilted base, at an intermediate location between a receiving member for the packaging bags and a packaging machine. CONSTITUTION:A packaging bag 3 which is manufactured by a packaging machine 1 is loaded sideways on a flattening means 15 in such a manner that the lower end part in which an object 2 to be packaged is comparatively more packed is located at the carry-in part of the flattening means 15, by advancing a longitudinal guide plate 37 in parallel to a position shown by broken line by a crank 46 and connection rod 47, etc., by the operation of a motor 41. Under this condition, a plurality of rotors with protuberance 18 rotate by a motor 24, and a belt 17 rotates together with the rotors with protuberance 18. By this operation, the packaging bag 3 is moved diagonally upward, and during this process, the deviation of the object to be packaged 2 in the bag 3 is corrected. Then, on a receiving member 6, a pressing member 11 is lowered to press the packaging bag 3 from the top, and the packaging bag 3 of which the descending distance being detected by a distance detecting member 12 at this time is a set value or more is judged to be a defectively sealed bag.
