DISPOSITIVO PARA O REVESTIMENTO DE OBJETOS COMO GARRAFAS DE VIDRO COM UM MATERIAL SINTETICO

摘要

Glass bottles (2) are coated with a synthetic material using a nozzle head (3) with a plurality of spaced nozzles (11-13) adapted to eject the synthetic material with successive droplets. Relative movement is effected between the surface of the bottle and the nozzle head and the nozzles are so arranged with respect to the direction of the relative movement that the traces of the synthetic material emerging from adjacent nozzles overlap on the container. The relative movement is coordinated with the ejection rate of the droplets so that the surface areas of the bottle coated with successive droplets from the same nozzle overlap.
