A cam actuator in a creme sandwich filling machine having a rotating annular drum containing four rows of pistons for extracting filling material from a hopper and depositing a layer of the material on a base cake. A series of identical cams are mounted on a shaft coaxial with the drum, and the pistons are moved radially with respect to the drum by cam followers engaging the cams. The cams are formed so that translation thereof along the axis of the drum brings the cam followers into contact with a different cam contour to adjust the stroke of the pistons. |
