ABSTRACT:
A pillow type packaging apparatus has a suction belt for conveying flexible continuous sheet material. A guide unit guides the continuous sheet material being conveyed, and forms the continuous sheet material into a quadrangular tube in which a pair of its longitudinal edges are confronted with each other. A center sealer thermally seals up the longitudinal edges. An inserter inserts an article into the tube through the guide unit. The tube is formed into a packaging bag by cutting and sealing. In the guide unit, an inner guide frame is inside an outer guide frame. The outer guide frame includes first to fourth corner portions, which are disposed in a quadrangular shape, have inside edges in contact with the continuous sheet material, and shape the continuous sheet material into the tube. The first to fourth corner portions are movable in directions of width and height of the continuous sheet material. The tube is changeable in a size. The inner guide frame includes fifth to eighth corner portions, which respectively correspond the first to fourth corner portions, are disposed in a quadrangular shape, contact the continuous sheet material, and maintain the continuous sheet material shaped in the tube inside the first to fourth corner portions. The fifth to eighth corner portions are movable in the directions of the width and height with respective distances therefrom to the first to fourth corner portions kept unchanged.
