HIGH PRESSURE RECIPROCATING SUCTION ROLL SHOWER

摘要

A high pressure shower system for cleaning perforations in a suction roll of a paper-making machine is disclosed. An elongated header pipe is mounted to the outside of the suction box and is fitted with a plurality of spaced high pressure nozzles directed at and in close proximity to the inside surface 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 to the header passes through the inside of the suction box which has a sealed slot opening to accommodate the reciprocal movement of the header.
