Zusammenfassung:	Apparatus for positioning a number of nondestructive dud detectors above a conveyor includes side support members to which a rotatable threaded positioning bar is mounted. The positioning bar includes a number of serially placed threaded positioning segments. The dud detectors are supported by the positioning bar through individual dud detector supports. Each dud detector support includes a threaded block which engages the threaded positioning bar. The threaded positioning segments have threads with different pitches. Rotation of the positioning bar cause the dud detectors to move axially along the positioning bar, and thus transversely over the conveyor belt, at unequal rates. The thread spacing or pitch for each threaded positioning segment is chosen so that the separation between adjacent dud detectors changes while keeping the dud detectors equally spaced. Since the detectors are always evenly spaced relative to one another, boxes of different sized containers passing beneath the dud detectors on the conveyor belt can be easily and quickly accommodated by simply positioning the first and last dud detectors over their respective containers. The interior dud detectors will automatically be aligned over the interior containers.
