Abstract
An automatic packaging machine has mandrels with a plurality of fingers for gripping an object. A cam track has contours which defines the location of positions along a conveyor carrying the mandrels. The fingers are closed by a spring and opened by a cam follower encountering a contour of cam track. This way a plurality of objects having a variety of widths may be carried by the fingers without requiring a readjustment of the machine.
