A supply device which, in a retainer type continuous-filling packaging system, converts the movement of empty bags supplied intermittently in a plurality of rows into a continuous motion in a single row and supplies these empty bags continuously to retainers that are conveyed at a constant speed. The supply device includes an empty-bag holding member conveying device and an intermittent bag supply device. In the empty-bag holding member conveying device, a plurality of empty-bag holding members (that contain therein empty bags) disposed at equal intervals are moved in one direction along a ring-form track that has a pair of parallel sections, and during this movement, the empty-bag holding members are moved intermittently by a specified distance (a distance equal to an integral multiple of an attachment spacing of the empty-bag holding members) on a bag entry side of the parallel sections and are moved continuously at a constant speed on a bag exit side of the parallel section. The intermittent bag supply device simultaneously supplies empty bags to the plurality of empty-bag holding members (with one bag being supplied to each empty-bag holding member) on the bag entry side. On the bag entry side, empty bags are supplied in a plurality of rows to stopped empty-bag holding members by the intermittent bag supply device; and on the bag exit side, the empty bags are successively extracted from the continuously moving empty-bag holding members and supplied to the retainers that are continuously conveyed.
