ABSTRACT:
In a shoe press belt of a papermaking machine, the part of the paper web-facing layer in which water-holding grooves are formed is composed of a surface sublayer, having a relatively low hardness, and an underlying layer having a relatively high hardness. The higher hardness of the underlying layer prevents cracks from forming where the cross-sectional shape of the grooves tends to change as the belt is compressed. The lower hardness of the surface sublayer prevents the formation of cracks as a result of forces acting on the belt in the direction opposite to the machine direction at the nip location in a papermaking machine.
