Cam 1, a round eccentric, rotates about fixed axis A. Followers 2 and 3 reciprocate in fixed guides C and B, whose axes intersect at point A forming a right angle, and have flat faces a and b, perpendicular to the axes of motion of the followers, which slide along the contour of cam 1. When cam 1 is turned, follower 2 is displaced a distance x=e*cos(φ) and follower 3 a distance y=e*sin(φ) where e is the eccentricity and φ is the angle of rotation of cam 1. Followers 3 andJ2 are held in contact with cam 1 by springs 4 and 5.
