20150316432 | METHOD AND SYSTEM ASSOCIATED WITH A SENSING ROLL AND A MATING ROLL FOR COLLECTING ROLL DATA - 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. | 11-05-2015 |
20150316430 | METHOD AND SYSTEM ASSOCIATED WITH A SENSING ROLL INCLUDING PLURALITIES OF SENSORS AND A MATING ROLL FOR COLLECTING ROLL DATA - Collecting roll data associated with a sensing and mating rolls that form a nip uses first and second pluralities of sensors.

The sensors are located at axially spaced-apart locations of the sensing roll and generate either a first or second respective signal when entering the nip. Upon receiving a generated signal, a determination is made about which sensor generated the received signal and the membership of that sensor in one of the pluralities. Based upon a rotational position of the mating roll, a determination is made of which tracking segment associated with the mating roll enters the region of the nip concurrently with the signal to store the signal using the determined one tracking segment and the determined membership. | 11-05-2015 |
20150316429 | METHOD AND SYSTEM ASSOCIATED WITH A SENSING ROLL AND A MATING ROLL FOR COLLECTING DATA INCLUDING FIRST AND SECOND SENSOR ARRAYS - Collecting roll data associated with a sensing roll and a mating roll forming a nip includes generating sensor signals from a first sensor array on the sensing roll and a second sensor array on the mating roll during rotations of the mating rolls and sensing rolls. A periodically occurring first time reference is associated with each rotation of the mating roll and a periodically occurring second time reference is associated with each rotation of the sensing roll. For a received sensor signal, based on whether the received signal is from the sensors of the mating roll or the sensing roll, a tracking segment on the other roll is detected that enters a region of the nip concurrent with the sensor that generated the received signal. The detection is made from either a most-recent-identified first time reference or second time reference. The received signal can then be stored using the detected tracking segment. | 11-05-2015 |
