Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
203 words
A system for monitoring the moisture content of a web substantially across the entire width thereof, comprising: roll means disposed substantially across the width of a web for detecting the moisture content thereof as the web continuously moves in contact with a predetermined portion of said roll means; means for moving said web continuously in contact with a predetermined portion of said roll means; means for electrically isolating both ends of said roll means, said electrically isolating means comprising: first and second bearing means, one operatively mounted to each end of said roll means, for providing for rotation of said roll means about an axis, and with respect to a housing of each of said bearing means; first and second support rods, one extending radially outwardly from each of said first and second bearing means; first and second support sleeves for mounting each of said first and second support rods; and a sleeve of electrical isolation material operatively disposed between each of said first and second support rods and its respective support sleeves; and means for detecting the amount of liquid retained by the web at said roll means, said detecting means being electrically coupled to said roll means at one end thereof.
