Abstract
A packaging machine includes a shaping device including a conveyor drive mechanism and a bottom tapping mechanism and shaping a packaging bag filled with article so that the bag has a predetermined thickness. The conveyor drive mechanism includes a pair of side conveyors movable forward and backward. The conveyors are capable of pressing the bag filled with the article when moved forward. The conveyors are configured to be run in parallel to the moving direction of the bag substantially in synchronization with movement of the bag. The tapping mechanism includes a receiving plate disposed over the filling step and one or more steps following the filling step. The receiving plate is moved up and down so that the bag bottom is tapped, when the bag filled with the article is stopped between the filling step and one or more steps following the filling step.
