The cam consists of main lobe member 1, rotating about fixed axis A, and two lobe members, 2 and 3, which can be adjusted to various positions with respect to member 1. For the purpose of adjustment, members 2 and 3 have curvilinear s lots a, which can slide a long bolt D, and straight slots b, which can slide along the shaft of member 1. Lobe members 2 and 3 can be rigidly clamped on member 1 by means of a nut on bolt D. Follower 4 reciprocates in fixed guide B and carries a roller that rolls along the working surface of the cam. By clamping members 2 and 3 in various positions, the stroke of follower 4 can be varied within the limits from x_min to x_max. The roller of follower 4 is held in contact with the cam by spring 5.
