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).

Dependent claims

A roll cleaning brush for application to a rotating roll comprising:

an elongate brush element holder formed with a longitudinally extending open-mouthed channel;
a plurality of brush elements, each brush element including a brush element base and tufts of brush bristles projecting from the base in a series of parallel rows extending longitudinally of the brush and spaced apart across the brush with the tufts of successive rows staggered with respect to one another longitudinally of the brush, the brush elements held captive within the channel of by the brush element holder in an array extending along the brush element holder so that the tufts of bristles project from a mouth of the channel but are movable toward and away from the open mouth of the channel and the tufts of bristles 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 brush element holder to allow the brush tip to vary in shape substantially continuously throughout its length to conform during operation to the roll surface to be cleaned;
and
biasing means, acting continuously between the holder and the brush elements, to bias the brush elements toward positions in which the brush tip is substantially straight, said biasing means including an elongate resilient compressible element extending along a root of the channel between the brush element bases and the holder to bias the brush element bases toward the mouth of the channel.
