Abstract
A press felt for use in the press section of a papermaking machine includes a base fabric and at least one layer of an assembly of fibers, preferably forming a carded web or batt, the assembly of fibers containing a plurality of fibers having a deep grooved configuration. The deep-grooved fibers of the press felt provide improved dewatering properties to the press felt as compared to conventional round monofilaments of the same denier currently employed as the batt in press felts used in the press sections of papermaking machines. A method for at least partially dewatering a sheet of paper fibers within the press section of a papermaking machine includes positioning the sheet of paper fibers on the press felt described herein, transporting the sheet of paper fibers through the press section, and pressing the sheet to at least partially remove the water therefrom.

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.
