The re-dampness for paper making and the cardboard the press cloth which is not done (10) the case of the compressed aspect in the press nip, the water passing, barrier layer (27) it is pushed out, but in the expansion aspect, the web (24) it seems that prevents the fact that it flows backward, barrier layer (27) it includes. Barrier layer (27), for example, apex opening of the structure compared to square, rectangle, tetrahedral, circular or long have small bottom opening elliptical conical connotation ones (30) seems the way, it is consisted of continual material possession ones. These funnels (30) each forms the check valve effectively, at the same time, makes the vacuum zone which prevents the re-absorption of the water by the paper seat. Under pressure, barrier layer (27) as for structure the water the cone (30) in and makes that it flows to outside small bottom opening possible. In the expansion aspect, as for small bottom opening of the structure restricting the counterflow of the water, it creates vacuum zone on other side. Vacuum zone the press cloth (10) increases the holding power of the water in, at the same time, the paper seat (24) prevents the re-dampness. With another execution example of this invention, barrier layer (27) it exists as the separated cloth which is supplied through the press section. With this execution example, as for separated cloth it is just the conical connotation thing seat that itself, seat that itself forms the belt of this invention which has possessed the quality which the re-dampness is not done.
