There is described a machine for packaging products in tubular wrappings of thermoplastic material obtained from continuous film unwound from a reel, equipped with a double transverse heat-sealing and intermediate cutting assembly (13) that, with a horizontal translation movement, accompanies the pack that the assembly (13) is closing the trailing end of to be unloaded while it is simultaneously closing the leading end of the tubular wrapper of the future pack that the heat-sealing and cutting assembly (13), also due to the presence thereon of pressers and counter-pressers (63, 163, 63', 163'), extracts from a tube-forming and longitudinal heat-sealing mandrel (1) and that, by the same assembly (13), is separated from the pack upstream with a transverse cut. At the end of its active movement, the transverse heat-sealing and cutting assembly (13) opens and with a horizontal movement in the opposite direction to and at a higher speed than the preceding one returns to the cycle start position, upstream of a new pack already filled and ready to be heat sealed at the trailing end and accompanied to be unloaded, repeating the cycle described. The transverse heat- sealing and cutting assembly (13) is aided by a conveyor (41) that supports and advances the packs being formed and those finished and separated, and that is equipped with a gap (40) with variable geometry, which opens during the active horizontal movement of the same assembly (13) and closes during the reverse horizontal movement of the same assembly (13).
