Pulley 2 rotates about fixed axis A. Six identical pulleys 3 rotate about axes B of disk 1 which rotates about fixed axis D. Endless flexible link 4 runs over pulley 2, two guide rollers 5, rotating about fixed axes, and six pulleys 3. The resultant motion of pulleys 3 is the sum of their independent rotation due to the rotation of pulley 2 and of disk 1.
