Abstract
A device is disclosed for cleaning the discharge gap of a jet nozzle of a web coating line or the like. The cleaning device comprises a body member slidably mounted on or adjacent the jet nozzle in such a way as to be shiftable longitudinally of the jet nozzle between the ends thereof. A clean-out blade is mounted on the body member and has a free end extending into the jet nozzle discharge gap. Manually actuable or mechanical means are provided to shift the body member between the ends of the jet nozzle to cause the free end of the clean-out blade to clean the jet nozzle discharge gap.
