Cylinder cam 1 rotates about fixed axis A-A and has profiled cam groove a-a. Followers 2 and 3 reciprocate in fixed guides C-C and B-B, and carry tapered rollers 4 which roll and slide along groove a-a. Owing to the symmetrical location of followers 2 and 3, whose axes of motion are parallel to axis A-A, the followers have the same type of motion, but displaced by a phase angle of 180°.
