Abstract
A method of manufacturing and a papermaker's or industrial fabric, such as a dryer fabric for the dryer section of a paper machine, includes the application of a polymeric resin material onto preselected locations on the backside of a base substrate using a piezojet array which deposits the polymeric resin material in droplets having an average diameter of 10μ (10 microns) or more to build up discrete, discontinuous deposits of the polymeric resin material having a height of about 0.5 mm at the preselected locations. The preselected locations may be the knuckles formed by the interweaving of the yarns making up the fabric. The purpose of the deposits is to separate the backside of the dryer fabric from a surface, such as that of a dryer cylinder or turning roll, to enable air trapped between the dryer fabric and the surface to escape in lengthwise and crosswise directions parallel to the surface, instead of being forced through the fabric, possibly causing 'drop off'. The polymeric resin material is set by means appropriate to its composition, and, optionally, and, if necessary, may be abraded to provide the deposits with a uniform height above the surface plane of the base substrate.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
