The device seals the open ends of monodose containers (2), which have already been filled with liquid or viscous solutions. The two versions of the invention permit the sealing of the containers without the need to trim the ends (8) once they have been sealed by heat welding. Both versions have grippers (10,20), with jaws (15,16,25,26) respectively which have the approximate shape of a comb. In the first version, the jaws (15,16) have square prongs (15A,16A) which are counter opposed when the gripper (10) is closed. A comb-shaped head (17) inserted in the prongs (15A,16A) of the jaws (15,16) prevents the formation of irregular edges at the ends (8) which would otherwise require trimming. In the second version, the jaws (25,26) are positioned when the gripper (20) is closed so as to prevent the formation of irregular edges at the ends (8). A flat-faced head (27) closes the prongs of the gripper (20) to prevent the formation of irregular upper edges. <IMAGE> |
