An article-supplying assembly for a vertical pillow type packaging machine has a first substantially cylindrical member extending vertically downward, a guiding member connected to the first substantially cylindrical member for guiding an elongated sheet of bag-making material from a front side to move downward along the first substantially cylindrical member, a second substantially cylindrical member inserted into the interior of the first substantially cylindrical member, and a funnel member for receiving articles falling from above. This funnel member is connected to the second substantially cylindrical member along a junction line, extending upward from the second substantially cylindrical member and allowing the received articles to fall through the first substantially cylindrical member downward. The junction line is at a highest point on the front side and at a lowest point on the backside. The ratio of the height difference between the highest and lowest points of the junction line with respect to the diameter of the cylindrical member is equal to or greater than 1.4.
