ABSTRACT:
Cleaning apparatus for a roll placed in contact with a metal strap moving longitudinally in an installation comprising a set of rotary-mounted superposed rolls between two stands of a fixed supporting cage and comprising at least one wiping tool (4) parallel to the axes of the rolls, a device (3) supporting the wiping tool mounted slidingly on straight guide rollers (24, 24') provided on a cradle (2) pivotably mounted on both stands (11) of the cage (1) around a pivot axis (20) parallel to the axes of the rolls. The cradle (2) comprises two spaced parallel flanges (21) linked rigidly by a crossbeam (22) and rotatably mounted, respectively, on two bearings fixed, respectively, on both stands (11) of the cage (10) and placed so that the cradle (2) can pivot between a working position in which the sliding plane of the supporting device (3) is oriented to the roll (1) to be cleaned and a maintenance position in which the sliding plane is removed from the roll ( 1) and the supporting device (3) is placed along both stands (11) of the cage (10), slightly extending in from the roll (1) and is placed along both stands (11) outside the cage, the supporting device extending in cantilever, in forward position, beyond the guide rollers (24, 24') to its front section (36) carrying the wiping tool (4) is located close to the roll (1) and the front section (36) is brought back of the cradle (2) in the rearward position of the frame (3) to allow the cradle (2) to pivot to the maintenance position along the stands (11) of the cage.
