Abstract: A device for cleaning the nozzle openings of a floater oven having duct-like nozzles with rows of nozzle openings along their length. A main frame which may be disposed adjacent to the oven nozzles is provided as a support structure. A main carriage adapted to travel back and forth along the length of the main frame is slidably mounted on the frame. A set of brushes adapted to be driven in rotation are mounted on the main carriage so they may be positioned in contact with the nozzle openings to be cleaned. In operation, the main frame is located adjacent to an oven nozzle. The main carriage is transported along the main frame as the brushes are rotated. The brushes automatically clean the nozzle openings along the nozzle.
