    • 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.
    • 一个与一个滚花滚筒配合并用于纸幅脱水的抽吸盒,其端部分别包括一个玻璃滑板,其中每个滑板的设计使得它能够弹性地屈服于滚花滚筒的外周面。 每个滑梯都是耐磨的,适用于不同的轮盘直径和浸渍深度。 因此,每个卡片滑动件包括薄片包装,其沿其纵向轴线沿着卷筒纸行进的方向延伸。 薄片包装包括多个平行的刚性薄片,它们可相对于彼此移位并且位于大致垂直于卷筒纸行进方向延伸的相应平面中。
