The present study investigates the pressure characteristics of a two-dimensional air-cushion pad in order to determine the effect of the fringe of the pad on the cushion pressure. Two-dimensional experimental models are used : in model (1), the width of the fringe is varied, and in model (2) its width is very large. The present experimental results show the following : (1) The effect of the fringe on the cushion pressure is fairly large ; the cushion pressure dicreases remarkably with the increase of the width of the fringe for l/h≤ 5 but the cushion pressure becomes almost constant for l/h≤5, where l and h are the width of the fringe and the clearance of gap, respectively. (2) The decrease of the cushion pressure is caused by the circulatory flow which is formed in the gap between the surface of the goods and the fringe of the pad, and the pressure at the edge of the fringe is almost atmospheric pressure.
