<p>A high pressure shower system for cleaning perforations in a suction roll of a paper-making machine is disclosed. An elongated header pipe (60) is mounted to the outside of the suction box (20) and is fitted with a plurality of spaced high pressure nozzles (62) directed at and in close proximity to the inside surface (38) of the suction roll. The header pipe is driven in a longitudinal reciprocating manner providing complete spray coverage of the suction roll perforations. The water supply conduit (66) to the header (60) passes through the inside of the suction box (20) which has a sealed slot opening (68) to accommodate the reciprocal movement of the header.</p> |
