Abstract (en)
[origin: WO8605219A1] A flat structure permeable to liquid, especially to a press felt for use in a papermaking machine, the structure being made up for a body (1) made of a castable polymer, the body having holes (2) formed during the casting process and possibly cavities (6), the diameter of the holes increasing substantially progressively from one surface to the other in such a way that the web-side surface is microporous and the other surface has pores substantially more open. The invention also relates to a method for the manufacture of such a structure.
