| Summary: | There is described a packaging machine (
1
) for producing sealed aseptic packages (
2
) of a pourable food product from a tube (
3
) of packaging material fed along a vertical path (A) and filled continuously with the food product. The machine (
1
) has gripping means (
13, 14
) for gripping the tube (
3
) at equally spaced cross sections (
15
); and sealing means (
23, 24; 34, 35
) for sealing the packaging material of the tube (
3
) along the cross sections (
15
), and in turn having a first and a second sealing device (
23, 24; 34, 35
) forming part of respective distinct, successive units (
10, 20
) of the machine (
1
). The first sealing device (
23, 24
) interacts with the cross sections (
15
) of the tube (
3
) for a time (T
1
) shorter than the time (T) required to achieve complete sealing of the cross sections (
15
), but sufficient to form respective temporary aseptic transverse sealing bands (
25
); and the second sealing device (
34, 35
) interacts with said temporary sealing bands (
25
) to seal them completely. (FIGS.
