Abstract
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.
