A rotary feeder module for feeding sheet inserts and having a thickness detector for measuring the thickness of moving inserts. The feeder includes a gripper drum disc for transporting the inserts and a detector caliper assembly having a follower roller that rides upon and along the periphery of upon moving inserts transported upon the periphery of the gripper drum disc. The feeder also includes a mechanism for sensing the field of a magnet to provide a measure of relative displacement between the sensor and the magnet and thereby a measure of the radius of the periphery from an axis of rotation. The sensory mechanism provides reference signals corresponding to zero thickness of the inserts in the absence of inserts upon the gripper drum disc. The sensory mechanism also provides thickness signals corresponding to the thickness of the inserts in reference to the reference signals when the inserts are transported upon the gripper drum disc interposed between the follower roller and the periphery.
