An apparatus (1) for closing and transverse separation of a continuous tubular element (T) for manufacturing packing sacks (200) which is composed by a vice (2) with two jaws (3) and counteracting jaws (4) spaced at a distance and intersecting in vertical plane the slipping tubular element, (T), a cutting group (5) placed between jaws (3) and connected to them by movement elements (6) suitable for separating contiguous extremities (201) of packing sacks (200) once the two surfaces(T1, T2) of each extremities (201) have been steadily joined by jaws (3) and counteracting jaws (4). The apparatus is provided with a sealing group (7) arranged between the cutting group (5) and each couple of jaws (3) and counteracting jaws(4) suitable for folding and joining the terminal part (202) of extremities (201) stretching out from jaws (3) and counteracting jaws (4) once they have been separated. |
