Patent number: 10378980Abstract: 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.Type: GrantFiled: May 2, 2014Date of Patent: August 13, 2019Assignee: INTERNATIONAL PAPER COMPANYInventor: Kerry D.

Patent number: 10378150Abstract: 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.Type: GrantFiled: June 13, 2017Date of Patent: August 13, 2019Assignee: INTERNATIONAL PAPER COMPANYInventor: Kerry D.
