Press Felt Selection Guide: Press Position, Base Fabric, Batt, GSM and Permeability
A complete press felt selection workflow covering press position requirements, base fabric construction, batt fiber design, GSM, permeability, void structure, nip configuration, seam selection, conditioning, and controlled trial planning — all tied to your paper machine operating baseline.
Read ArticlePoor Nip Dewatering: What to Check Before Changing a Press Felt
A practical investigation sequence for poor nip dewatering that separates press-felt observations from machine, roll, shower and operating-condition checks.
Read ArticleHow to Assess a Press Felt Before Replacement: A Practical Mill Review
A press felt should be assessed in the context of its own press position, paper grade and running conditions. A single appearance check or one instrument reading rarely explains whether a felt needs attention, a planned change, or a broader press-section review.
Read ArticlePress Felt Permeability Review: Field Data Checklist Before a Replacement RFQ
When a mill requests a replacement press felt because of a permeability concern, the most useful starting point is not a single target number. A reading can support a technical discussion only when the mill also records how, where and when it was taken, together with the press position and current operating observations.
Read ArticleKraft Paper Press Felt: An Anonymised Project Profile
Press-felt selection influences water handling, sheet surface, runnability and the moisture carried into the dryer section. This anonymised project profile sets out the data and engineering checks PAPTEX uses before recommending a press fabric for a kraft or packaging-paper machine.
