A cut and seal unit (1) for sheet material (4), wherein an actuating unit (8) has a single powered input (9), and two identical output transmissions (10, 11) linked to each other and to the input (9); the two output transmissions (10, 11) are connected to respective cut and seal tools (7', 7), which are moved by the actuating unit (8) along respective substantially ellipsoidal trajectories (T', T) on either side of a path (P) of the sheet material (4) extending through the two trajectories (T', T), and cooperate cyclically with each other at a cut and seal station (5) along the path (P) to transversely cut and seal the sheet material (4). <IMAGE> |
