Abstract
A dewatering member for a paper or board machine has a composite body () and a hard surface layer (). The composite body () is manufactured in a pultrusion process. An adhesion layer () is formed on desired outer surfaces of the composite body () such that reinforcements passed to the adhesion layer () have been passed to the pultrusion process through a separate resin bath, to which an adhesion improving agent has been added such that the hard surface layer () can be applied directly onto it, and reinforcements forming the inner portion of the composite body () have been passed to the pultrusion process through a second resin bath. The composite body () is coated with a hard coating layer () produced by thermal spraying, and the coating () is ground.
