Kind Code:
B2
Abstract:
A wet paper web transfer belt (1) has a wet paper web-side layer (31) including a resin and a hydrophilic fibrous body (30) and a machine-side layer (32). A basic fabric (33) disposed in the belt comprises a first woven fabric (34) disposed on a wet paper web (W) side and a second woven fabric (35) disposed on a press roll (10) side. The first woven fabric (34) and the second woven fabric (35) are stacked together. At least a portion of the hydrophilic fibrous body (30) is exposed on a surface (37) of the wet paper web-side layer (31). The basis weight of the first woven fabric (34) is greater than the basis weight of the second woven fabric (35). The structure is effective to improve a first function to cause the wet paper web (W) to stick thereon and to transfer the wet paper web (W), and a second function to allow the wet paper web (W) to be smoothly released from the belt for transferring the wet paper web (W) to a next process. The belt (1) has opposite edges (E) prevented from being curled while the belt (1) is traveling.
