Abstract
A screening device for fibrous stock suspensions of the paper industry includes at least two separate screening baskets which are connected axially behind one another in the interior of a reinforcing device in the form of a back-up cylinder. A variable-diameter intermediate ring is arranged between the screening baskets. The reinforcing device has a cover part and a bottom part. By way of axial tensile force loading of the arrangement, the intermediate ring is loaded so as to bear radially in the circumferential direction in a gap-free manner against the associated axial ends or screening basket flanges of the screening baskets. The screening baskets are then clamped and fixed in a centrally positioned manner by the intermediate ring in cooperation with the end-side flange of the reinforcing device, the cover part, the bottom part and the intermediate ring.
