Abstract: Collecting data includes generating a sensor signal from each of a plurality of sensors located on a sensing roll, wherein each signal is generated when each sensor enters a region of a nip between the sensing roll and mating roll during each rotation of the sensing roll; wherein a web of material travels through the nip and a continuous band, which also travels through the nip, contacts a region of the web of material upstream from or in the nip. A periodically occurring time reference is generated associated with each rotation of the continuous band and the signal generated by each sensor is received so that the one of the plurality of sensors which generated this signal is determined and one of a plurality of tracking segments associated with the continuous band is identified. The signal is stored to associate the respective sensor signal with the identified one tracking segment.

Abstract: A tissue paper crimper of greater rigidity is provided by mounting crimper disks to linear bearings which in turn are mounted to a carriage which can be positioned in the cross machine direction on a frame. The crimper disks are pressed against anvil roll pneumatic actuators. The use of linear bearings allows the crimper to run at higher operating speeds.

Buildup of fibers on the crimping wheels from the tissue webs being crimped can cause the wheels to become unbalanced, resulting in undesirable vibration. The rigid mounting and the prevention of fiber buildup will allow the crimper of this invention to operate at higher machine speeds.
