Improved Fabric Cover for Dampener Rolls Abstract An improved fabric for covering dampener rolls comprising a ground yarn, a water shrinkable inlay yarn and a hydrophilic pile yarn. The fabric is fashioned into a cylindrical tube and is securely fastened to a roll by thoroughly wetting the tubular fabric and roll in water until the water shrinkable inlay yarn shrinks causing the fabric to tighten down on the roll. When the inlay yarn of the dampener cover shrinks it does so in a widthwise or circumferential manner, thereby exerting a force upon the surface of the dampener roll similar to the force exerted by a series of rubber bands, thus securing the dampener cover to the dampener roll. This unique fabric construction also allows for a reduction in lengths of fabric needed to cover a roll, because the fabric shrinks circumferentially and not lengthwise. Thus, a cover may be measured more precisely to the length needed to cover a specific roll.
