Abstract

In a one-surface coated papermaking belt composed of a base layer and a thick resin layer, or a covered, one-surface coated papermaking belt composed of thin and thick resin layers on opposite sides of a base layer, curling of the edges of the belt due to the shrinkage of the thick resin layer is reduced by forming the opposite side edge parts of the thick resin layer thinner than the middle part. The reduction in curling results in improved oil removal especially in a shoe-press belt. It also stabilizes turning of the belt and facilitates belt installation.
