CLAIMS
1) Vertical packaging machine with two opposite forming tubes, characterized by the fact that it is made up of two different vertical packaging groups 1 and 2 , which are set on the opposite sides 3 and 4 of a central structure 5 that is equiped with a horizontal bilateral station 6 that carries out the trasversal sealings of both resulting packets 15 and 16.
2) Vertical packaging machine with two opposite forming tubes, as in claim 1) characterized by the fact that the bilateral station 6 is provided with sealing pincers 7 and 8 which are set one on the side 3 and the other one on the side 4 and are each other connected by the connection rods 9 and 10.
3) Vertical packaging machine with two opposite forming tubes, as in the previous claims characterized by the fact that the motion of each connection rod 9 and 10 influences both the processes of trasversal sealing that are carried out on the side 3 and on the side 4.
4) Vertical packaging machine with two opposite forming tubes, as in the previous claims characterized by the fact that the motions of the connection rods 9 and 10 come from kinematic motions 11 made by only one central shaft 12.
5) Vertical packaging machine with two opposite forming tubes, as in claim 1 characterized by the fact that both vertical packaging groups 1 and 2 can be fed with flexible material 13 coming from only one roll 14.
