ABSTRACT:
All the carousels of the machine are provided with grippers for holding the flasks. A carousel with grippers (6) for holding the flask by the neck is followed by a carousel with grippers (7) for holding the flask by the body and so on. Between the jaws of each gripper there is provided in the middle region a vertical opposition element (35) fixed onto a horizontal slide (36) supported by the gripper body (33) and connected to a mechanism which modify the position of the said opposition element according to the diameter of the flasks. The opposition element is directed towards the flask with a concave-profile front face. The orbits (29, 30) along which the grippers of two consecutive carousels travel intersect each other in the zone where the flasks pass from one carousel to the other. In this zone the flask is immediately held between the opposition elements of the opposite grippers of the carousels, which open and close alternately. The opposition elements of one of the two consecutive carousels are spring-mounted. Preferably the opposition elements of the grippers of the operating carousels are immobile and the opposition elements of the grippers of the service carousels are spring-mounted. Special variable-profile cams control the transfer of the flasks between the carousels of the machine.
