A supply device for supplying flattened boxes (1) to a packaging machine, equipped for the re-supply of the boxes (1), comprising apparatus for feeding a line (4) of boxes along a magazine (2) including a front carriage (13) and a rear carriage (14) feed chains (6, 8), flat vertical slides (19, 27) for connecting the carriages (13, 14) to the feed chains (8), a double action pneumatic jack (42) for sliding the carriages (13, 14) towards or away from one another, a plate (31) mounted on the carriage (13) moveable transversely between a position facing the line (4) and a retracted position, a plate (41) on the carriage (14) facing and normally spaced from the plate (31) to form a space containing additional boxes (1). To supply the additional line (46) of boxes, the plate (41) is first moved to compact the additional line (46) and thereafter plate (31) is retracted to provide a single line of boxes. The plate (31) is then moved adjacent the plate (41) and returned to apply pressure to the rear of the line comprising the original (4) and additional (46) boxes.
