Papermachine headbox cleaning system

摘要

Interior surfaces of a papermachine headbox slice plenum are mechanically cleaned by a method using scouring tools secured to a sled structure which is manually reciprocated within the slice plenum by tow ropes. Sled runners bear against the headbox tube sheet while the tool scouring bristles or surfaces compressively load against the convergent slice walls. Cleaning solution discharge nozzles supplied by a flexible conduit apply cleaning solution to the slice wall surfaces as the scouring occurs.
