ABSTRACT:
This invention relates to a method of and apparatus for forming a colored shade band on an elongated area of a flexible sheet of interlayer material comprising applying a dye composition by electrostatic spraying against an elongated area of a surface of a flexible sheet of non-conductive interlayer material such as polyurethane or plasticized polyvinyl butyral. A flexible sheet to be coated is mounted on a support carriage at a loading and unloading chamber in a substantially horizontal support plane, is transferred to a coating chamber, is tilted into an oblique plane at said coating chamber where it is aligned with a platen mask, electrostatic spray means disposed to one side of said platen mask supplies an electrostatic spray of a dye composition through said platen mask to the elongated area of said flexible sheet. The coated sheet pivots back to a substantially horizontal support plane and is returned to the loading and unloading station, where the coated flexible sheet is removed and another sheet mounted for treatment. The flexible sheet so coated is useful as an interlayer in shaded, bent laminated safety glass windshields.
