ABSTRACT:
The invention relates to a press roll arranged to interact with a second roll in the wet end of a paper or paper board machine for forming a nip between the rolls. In the press roll a surface is arranged to be pressed against the second roll and is made of an elastic material for extending the nip. In order to provide a simple and versatile structure, the surface made of an elastic material is formed by a separate shell portion which surrounds a body of the press roll and is positioned over its entire length at a distance from the body. The shell portion is supported to be stationary with respect to the body by means of end flanges provided in the ends of the body, so that the shell portion is able to yield over the entire length thereof radially inwards towards the body locally at the nip point.
