ABSTRACT:
A process and apparatus for forming a glass pane having an upper filter band, and possibly both an upper and lower filter band. The glass pane may comprise a lamina of a laminated safety glass for use as a windshield of a vehicle.
In the process filter strips are applied to a glass sheet as the glass sheet is moved through a chamber. The filter strips are applied as a family of filter strips which extend continuously along the glass sheet in the direction of its movement. The filter strips of the family are spaced apart laterally. Each filter strip may extend along a straight path, or the filter strips may be of repeating arcuate outline or of sineshaped outline, for example. The filter strips between a pair of marginal filter strips are of a width that may be greater than the width of the marginal strips, and the filter strips may vary in width along their continuous length. The process envisions subdividing the glass sheet into a multiplicity of blanks, each of which includes a part of one or two adjacent filter strips, and cutting a glass pane from the blank.
