Process and machine for packing pasty, liquid or semiliquid products comprising: nonstop feeding two sheets ( 1, 2 ) sandwiching ducts ( 3 ) ending in nozzles ( 4 ) feeding pasty, liquid or semiliquid products to be packed (M); nonstop longitudinally sealing the said sheets ( 1, 2 ) through longitudinal continuous beads ( 5 ) adjacent to the said continuous sleeves ( 6 ); forming through the said longitudinal sealing narrowings arranged at intervals longitudinally regular in the said sleeves ( 6 ) making possible the passage of the said ducts ( 3 ) and defining in the sleeves ( 6 ) long, wide lengths ( 8 ) and short narrow lengths ( 9 ); nonstop injecting with nozzles ( 4 ) material (M) within the said sleeves ( 6 ) which are inflated forming units ( 28 ) of material (M) with prior pressure closing of a narrow length ( 9 ) each sleeve advanced to each nozzle ( 4 ) while the sheets ( 1, 2 ) are moving forwards, and pressure closing and transversally sealing at regular intervals the said sleeves ( 6 ) filled with material (M).
