A shoe press belt is disclosed. The belt has both sides coated with a resin layer. At least one resin layer has side edge portions softer than the middle portion. The hardness of the edge portions may first decrease stepwise laterally outwardly from the middle portion to a section which overlies the shoe edge, and then increase stepwise laterally outwardly to the belt edge. A first stepwise reduction in hardness may begin laterally inward of the wet paper sheet edge and extend laterally outwardly to the wet paper sheet edge, where a second stepwise reduction begins that extends laterally outwardly beyond the shoe edge. Laterally outwardly of the second reduction, a stepwise increase in hardness extends to the belt edge. Alternatively, each edge portion may be of a single hardness, less than the hardness of the middle portion, with each edge portion overlying one of the shoe side edges. |
