ABSTRACT:
Harmonic vibrations in a signature machine due to the inertial influence of a reciprocating mass comprising grippers and associated parts are reduced by using a planetary gear drive and a weight secured thereto; momentum of the gripper mass is countered by another rotating weight. The planetary gear drive may be either epicyclic or hypocyclic, depending principally upon the length of the reciprocal stroke.
