A New Class of Forming Fabric Structures Can Widen Application Guideline Targets

A New Class of Forming Fabric Structures Can Widen Application Guideline Targets

Traditional forming fabric structures involve a series of design compromises in which fabric life, fabric stability, sheet formation, fiber retention, and fabric drive-load are traded off, one for another, to achieve a specific end result. This article describes a new approach by Cristini Design Engineers, in which all these properties can be maximized without coincidental negative trade-offs.

Re-thinking Modern Press Fabric Design to Take Advantage of Nip Dewatering

Re-thinking Modern Press Fabric Design to Take Advantage of Nip Dewatering

During the introduction of Batt on Mesh (BOM) felts in the early 70's, it was shown that the inclusion of an incompressible component into the base enabled handling of higher water loads and providing longer life because of their inherent resistance to compaction and filling. The older Batt on Base (BOB) structures were known at the time to provide better water removal performance because of their better in-nip pressure uniformity, but the advantages of longer life, resistance to crushing at higher press loads, and better cleanability outweighed this consideration, particularly in an age of cheap energy.
