Claim:
1. A system associated with a sensing roll and a mating roll for collecting roll data comprising: the sensing roll and mating roll located relative to one another to create a nip therebetween, wherein a web of material travels through the nip from an upstream direction to a downstream direction and a continuous band, arranged to travel around in a loop pattern, contacts at least a region of the web of material at the nip or upstream from the nip; a plurality of sensors located at axially spaced-apart locations of the sensing roll, wherein each sensor enters a region of the nip during each rotation of the sensing roll to generate a respective sensor signal; structure for generating a periodically occurring starting reference associated with each rotation of the continuous band around the loop pattern; and a processor to receive the periodically occurring starting reference and the respective sensor signal generated by each sensor and, after receiving the respective sensor signal, the processor operates to:
