Abstract
Improvements in the mechanical devices for the drive of shears, characterized by the fact that the kinematic work cycle is obtained by the combination of a coupling clutch, an endless screw, coupled by means of said clutch to the motor shaft of the machine; a toothed crown, engaging with the endless screw, integral with the eccentric shaft that moves the movable blade; and a retaining cam, integral with the eccentric shaft, actuating said clutch and the brake of the machine in the sense of making one operative or inoperative to the other and vice versa.
