ABSTRACT:
An apparatus for treating a fiber suspension, comprises a drum rotatably journalled to a stand and having an envelope surface to support a fiber web formed from the fiber suspension. A curved wall plate which is concave in the direction to the envelope surface of the drum is spaced from the envelope surface (and generally parallel thereto) to define a material space therebetween for said fiber web. The space includes an axial inlet gap and an axial outlet gap. The wall is continuous and encloses a major portion of the envelope surface of the drum and is arranged to move freely in the circumferential direction of the drum to compensate for radial alterations during adjustment of the distance of the wall from the envelope surface at one or more positions between the inlet gap and outlet gap. Adjustment devices cooperate with the wall for adjusting the distance of the wall from the envelope surface of the drum. A support is joined to the stand for carrying the adjustment devices, each of the adjustment devices acting on and influencing a section, and only a section, of the wall and comprising a connection element positioned at the outer surface of the wall within the wall section.
