1. A machine for filling bags with a granular product, the machine comprising a filling station, a welding station, and a cooling station, wherein the machine further comprises:
[a] a supporting device for supporting the bags, which forms a unit arranged below said filling, welding, and cooling stations for supporting, during operation, a base of each of the bags that are located in each of said filling, welding, and cooling stations, said supporting device comprising:
[b] a supporting surface,
[c] a pivot shaft, and
[d] actuating means,
[e] said supporting surface being assembled on said pivot shaft such that said supporting surface has a first supporting segment facing said welding and filling stations on one side of said pivot shaft, and a second supporting segment facing said cooling station on an opposite side of said pivot shaft, and wherein
[f] said supporting surface, said pivot shaft, and said actuating means are functionally associated with one another such that said supporting surface can pivot in an alternating manner around said pivot shaft through said actuating means between
[i] an upper position of said first supporting segment and a lower position of said second supporting segment, and
[ii] a lower position of said first supporting segment and an upper position of said second supporting segment,
for moving a base of a bag which, in operation, is located in said filling station during filling.
