Cam 1 reciprocates in fixed guide D along axis B-B. Cam surface a is a plane inclined at a certain angle to axis B-B. Follower 2 oscillates about fixed axis A-A and carries roller 3 which rotates freely about axis C-C of follower 2 and rolls along cam surface a. Axes A-A and C-C intersect and are perpendicular to each other. Axis B-B of cam motion is parallel to axis A-A of follower oscillation. Roller 3 is held in contact with cam surface a by a spring (not shown).
