ABSTRACT:
A method and apparatus is described for obtaining a quantitative indication of paper web abrasiveness as the web subject of the test is in transit through the production machine. Test specimens of thin, sheet metal shim stock are held in light bearing pressure contact against the dry, finished or nearly finished web for a measured increment of web length. The measured quantity of specimen material lost to the measured quantity of passing web will yield a quotient indicative of the relative abrasiveness of the subject web.
