Abstract
A suction box coordinated with a dandy roll and serving the dehydration of paper webs features on its ends respective deckle slides wherein each deckle slide is of a design such that it elastically yields to the peripheral face of the dandy roll. Each deckle slide is wear-resistant and adaptable to varying dandy roll diameters and dipping depths. Thus, each deckle slide comprises a lamella package which extends with its longitudinal axis in the direction of web travel. The lamella package includes a plurality of parallel, rigid lamellae shiftable relative to one another and lying in respective planes extending generally perpendicular to the direction of web travel.
