  • Patent number: 5221347
    Abstract: Successive plate-like substrates are transported in a horizontal plane on a first conveyor beneath a first spray coating device on their way toward an inverting device which turns successive substrates through 180.degree. and deposits them on the supporting elements of a second conveyor which advances the once coated substrates beneath a second spray coating device. The twice coated substrates are advanced through a drying zone wherein they are acted upon at both sides by infrared heaters which expel the surplus of moisture. The supporting elements are in mere linear or point contact with the coated undersides of inverted substrates above the second conveyor. Such supporting elements can engage uncoated marginal portions of the substrates or the coated portions of undersides of substrates above the second conveyor. Coating material which bypasses the substrates is intercepted and collected, and the supporting elements are cleaned at regular intervals.
