PROBLEM TO BE SOLVED: To provide a packaging machine capable of shaping a large-sized packing bag filled with an article to be filled to a constant thickness with no variance without causing any decrease in production efficiency.SOLUTION: A packing bag filled with an article to be filled is tapped with a receiving plate 71 of a bottom striking mechanism to be shaped while pressed by both inner and outer side conveyors 57, 62 of a conveyor driving mechanism over a filling process 16, a shaping process 17, and an opening process 18 for a deaeration nozzle. The time needed to shape the packing bag can be made long without any influence on operation times of a process precedent to the filling process 16 and a following process. Consequently, the large-sized packing bag filled with the article to be filled can be shaped to the constant thickness without any variance. |
