A packaging machine comprising: a machine bed having a frame and a plurality of processing stations, one of said processing stations being a bottom breaking station; a rotor having a plurality of radial mandrels each for carrying a container fitted therearound, said mandrels being equal in number to said plurality of processing stations and being intermittently drivingly rotatable in a path so as to stop at each of said processing stations; a container bottom breaker provided at said bottom breaking station for performing an operation of folding the bottom portion of a container flat, said bottom breaker including a pressure operated cylinder mounted on said packaging machine and acting longitudinally of said mandrels upon said bottom portion whereby said folding operation subjects said container to a force acting longitudinally thereon; and container holding means provided at said bottom breaking station comprising at least one other pressure operated cylinder mounted on said packaging machine so as to apply pressure transversely of said mandrels and including a pressing member facing the path of movement of said mandrels so as to be pressed against said container at a side of a mandrel stopped at said bottom breaking station, said container holding means cylinder being controlled by application of pressure thereto to press said pressing member against said container when said mandrel is at rest at said bottom breaking station before said bottom breaker cylinder operates to perform a folding operation on said container to prevent longitudinal movement of said container on said mandrel due to said longitudinally acting force.
