    • Apparatus for cleaning the surface of a rotating roller (1). First and second cleaning blades (8, 9) each have an edge extending axially across the surface of the roller and adjacent thereto, the edges being parallel and directed against the direction of rotation of the roller. The edge of the second blade (9) is disposed behind the edge of the first blade (8) relative to the direction of rotation. Means are provided for causing relative movement of the blades to reverse the disposition of the edges and cause the edge of the blade (9) to scrape that surface of the blade (8) which faces towards the roller. During such movement the blade (9) is moved so that its edge contacts the roller to keep a constant cleaning action. The edge of blade (8) scrapes the surface of blade (9) as the blades return to their original disposition.
    • 用于清洁旋转辊(1)表面的装置。 第一和第二清洁叶片(8,9)各自具有沿辊子的表面轴向延伸并且与其相邻的边缘,边缘平行并且抵靠辊的旋转方向。 第二叶片(9)的边缘相对于旋转方向设置在第一叶片(8)的边缘的后面。 提供了用于引起叶片的相对运动以反转边缘的布置的装置,并且使得叶片(9)的边缘刮擦面向滚子的叶片(8)的表面。 在这种移动期间,叶片(9)被移动,使得其边缘接触滚子以保持恒定的清洁动作。 刀片(8)的边缘刮刀(9)的表面,因为刀片恢复原来的位置。
