This specification discloses a machine for making ice cubes in an inverted tray having a closure platen and having an improved cam for forcing the platen open at the beginning of the harvest cycle. In its preferred form a double eccentric cam is used. Generally there is clearance or slack that must be taken up at the beginning of cam rotation before maximum force is required. The cam is so oriented relative to the follower that maximum force is developed by the cam at a point of rotation after the slack has been taken up between the parts and also at a time when the platen is to be broken loose from the ice. The force is applied to the platen continuously through the entire time the platen is being broken away from the ice.
