Method and system associated with a sensing roll and a mating roll for collecting roll data

Abstract

Collecting roll data for a sensing roll and mating roll forming a nip includes generating a respective sensor signal from each of a plurality of sensors located at axially spaced-apart locations of the sensing roll, wherein each respective sensor signal is generated when each sensor enters a region of a nip between the sensing roll and the mating roll during each rotation of the sensing roll and receiving the generated signal. Upon receiving the signal, a processor a) determines a particular which of the sensors which generated the signal, b) based upon a rotational position of the mating roll relative to a reference position, determines which one of a plurality of tracking segments associated with the mating roll occurs substantially concurrently with the sensor entering the region of the nip, and c) stores the respective sensor signal to associate the signal with the determined one tracking segment.
