Abstract
A cut and seal unit for sheet material, wherein an actuating unit has a single powered input, and two identical output transmissions linked to each other and to the input; the two output transmissions are connected to respective cut and seal tools, which are moved by the actuating unit along respective substantially ellipsoidal trajectories on either side of a path of the sheet material extending through the two trajectories, and cooperate cyclically with each other at a cut and seal station along the path to transversely cut and seal the sheet material.
