Claim Text:
1. A method of monitoring and optionally controlling the application of a coating containing a Performance Enhancing Material (PEM) on a surface of a creping cylinder comprising: (a) applying a coating to the surface of the creping cylinder; (b) determining if a thickness of the coating is sufficiently non-uniform so as to exceed a threshold known to cause blade chatter by measuring the thickness of the coating on the surface of the creping cylinder by a differential method, wherein said differential method utilizes a plurality of apparatuses that do not physically contact the coating, wherein the plurality of apparatuses includes at least one apparatus selected from the group consisting of an IR-temperature sensor, a spectrometer, an inferometer, an ultrasonic sensor, a moisture measuring device, and a modulus measuring device; (c) adjusting the application of said coating in one or more defined zones of said creping cylinder in response to the thickness of said coating so as to provide a uniform thick coating on the surface of the creping cylinder; and (d) applying an additional device(s) to monitor and optionally control other aspects of the coating on the creping cylinder aside from the thickness of the coating.
