A bag-packaging machine has a conveying device (3) for transporting whole loaves (1) in the direction of a bundle of bags (4), a suction unit (12) which in each case opens the top bag (4a) of the bundle of bags (4), two spreaders which reach into the opened bag (4a) and hold the latter in the opened position, a pusher (18) which moves the whole loaf (1) into the ready-held bag (4a) and a bag-sealing device (15). The pusher (18) is constructed as a suction unit and has at its end a suction head (19/20) which conveys the whole loaf (1) into the opened bag (4a) and sucks a vacuum, drawing the neck of the bag (4b) tightly to itself after removal of the spreaders (13), thus holding the whole loaf (1) automatically and pushing it in this position as far as the sealing device (15). In accordance with a process for operating with this machine, the air is sucked out of the bag (4a) to such an extent that the bag (4a) presses tightly round the whole loaf (1) and the latter is held firmly against a change of position in the bag (4a).
