ABSTRACT:
A cam mechanism includes a cam of basic circular formation and having a lobe formation extending radially outwardly along part of its periphery; and a cam follower mounted for reciprocating movement along an axis perpendicular to the axis of rotation of the cam; the cam acting against an end face of the cam follower so that engagement of the lobe formation therewith will cause movement of the cam follower, the inclination of the face of the cam follower which is engaged by the lobe formation being adjustable to vary the duration of movement of the cam follower by the cam.
