<p>An object of the present invention is to provide a wet paper web transfer belt having excellent wet paper web transfer properties wherein such phenomena as "paper robbing" and "floating edges" are simultaneously prevented, and to provide a wet paper web transfer belt wherein the above-mentioned wet paper web transfer properties are realized for the different types of paper (in particular base paper of different basis weight) made in the papermaking step. According to the present invention, this is achieved by a wet paper web transfer belt 1 for transferring a wet paper web W, wherein the wet paper web transfer belt 1 includes a wet paper web contacting surface 221 for carrying the wet paper web. The wet paper web contacting surface is constituted by a resin layer 22. The wet paper web contacting surface 221 includes, in the width direction, sheet edge regions 222 for carrying the edge parts W E of the wet paper web W and a center region 223 for carrying the center vicinity of the wet paper web. The arithmetic average roughness Ra 1 (µm) of the wet paper web contacting surface 221 in the sheet edge regions 222 is smaller than the arithmetic average roughness Ra 2 (µm) of the wet paper web contacting surface in the center region 223, and prescribed roughness related equations are fulfilled.</p> |
