A method for feeding bags to a packaging machine, comprising the steps of: forming connected bags, in which bags are connected in a belt shape, in a horizontal bag-making machine while belt-shaped film is fed, successively, in its longitudinal direction; cutting and separating individual bags from said connected bags in said horizontal bag-making machine; allowing the bags fed out from said horizontal bag-making machine to be received on a conveyor and conveyed and then effecting positioning of the bags at a prescribed position on said conveyor; upwardly pulling out positioned bags, and changing attitudes of the bags to a vertical attitude in which bag mouths are oriented upward; moving the bags in a horizontal direction, toward a prescribed position, while the vertical attitude thereof is maintained; rotating the bags to orient one bag surface toward a next feed direction; changing the attitude of the bags from vertical to horizontal so that the bag mouths are oriented in a feed direction, and placing the bags on a feed conveyor; and conveying and feeding the bags on said feed conveyor toward a belt conveyor of a conveyor magazine-type bag feeder of the packaging machine.
