Abstract
A calipering assembly (40) is provided for use along a collating conveyor (14) having collated assemblages (20) thereon. The calipering assembly comprises a movable member (60) in the form of a wheel having an outer circumferential surface which engages a collated assemblage when the member is moved toward a collated assemblage. The outer circumferential surface of the member includes a light reflective surface portion (83) against which light (37) is directed and then reflected (38). A light sensor (39) senses the reflected light from the light reflective surface portion of the outer circumferential surface of the member. A processor (44) cooperates with the light sensor to provide a signal (42) which varies as a function of the thickness of the collated assemblage.
