Abstract
A roll cleaning brush (21) for application to a rotating roll (12) includes an elongate brush element holder (24), a plurality of brush elements (25) each including a brush element base (26) and brush bristles (27) projecting from the base (26). Brush elements (25) are held by the brush element holder (24) in an array extending along the holder so that the bristles (27) form a substantially continuous brush tip for application to a roll to be cleaned but so that the brush elements are independently movable transversely of the holder to allow the tip to vary in shape to conform to the roll surface to be cleaned. Brush element holder (24) is formed with a longitudinally extending open mouthed channel (28), and brush element bases (26) are captive within the channel such that the bristles project from the mouth of the channel but are movable toward and away from the open mouth of the channel. An elongate resiliently compressible pneumatic tube (31) extends along the root of the channel ( 28) between the brush element bases (26) and the holder (24) to bias the brush element bases (26) toward the mouth of the channel (28).
