Abstract
A sensor signal is generated from a plurality of sensors located on a sensing roll, wherein each signal is generated when each sensor enters a first nip between the sensing roll and a rotating component during each rotation of the sensing roll. A rotating applicator rod forms forming a second nip with the sensing roll such that each sensor enters the second nip during each rotation of the sensing roll. A periodically occurring starting reference is generated associated with each rotation of the applicator rod and the signal generated by each sensor is received so that a particular one of the sensors which generated the signal is determined and one of a plurality of tracking segments is identified. The signal is stored to associate the sensor signal with the identified one tracking segment.

A system associated with a sensing roll for collecting roll data comprising:
- a plurality of sensors located at axially spaced-apart locations of the sensing roll, wherein each sensor enters a region of a first nip between the sensing roll and a rotating component during each rotation of the sensing roll;
- an application station, comprising a rotatable applicator rod forming a second nip with one of the sensing roll and the rotating component;
- each sensor generates a respective sensor signal upon entering a region of the first nip;
- structure for generating a periodically occurring starting reference associated with each rotation of the applicator rod;
- and
- a processor to receive the periodically occurring starting reference and the respective sensor signal generated by each sensor as it moves through the first nip and, after receiving the respective sensor signal, the processor operates to:
- determine a particular one of the plurality of sensors which generated the respective sensor signal,
- based upon a value occurring between when the respective sensor signal was generated and a most recent starting reference, identify one of a plurality of tracking segments, wherein each of the plurality of tracking segments is, respectively, associated with a different value, and
- store the respective sensor signal to associate the respective sensor signal with the identified one tracking segment.
A method associated with a sensing roll for collecting roll data comprising:
- generating a respective sensor signal from each of a plurality of sensors located at axially spaced-apart locations of the sensing roll, wherein each sensor enters a region of a first nip between the sensing roll and a rotating component during each rotation of the sensing roll;
- providing an application station, having a rotating applicator rod with an axis of rotation substantially parallel to that of the sensing roll and forming a second nip with one of the sensing roll and the rotating component;
- each sensor generates a respective sensor signal upon entering a region of the first nip;
- generating a periodically occurring starting reference associated with each rotation of the applicator rod;
- and
- receiving the periodically occurring starting reference and the respective sensor signal generated by each sensor and, after receiving the respective sensor signal:
- determining a particular one of the plurality of sensors which generated the respective sensor signal,
- based upon a value occurring between when the respective sensor signal was generated and a most recent starting reference, identifying one of a plurality of tracking segments, wherein each of the plurality of tracking segments is, respectively, associated with a different value, and
- storing the respective sensor signal to associate the respective sensor signal with the identified one tracking segment.
