Abstract
Abstract A method of applying a clear glass primer material and then a black glass primer material onto the marginal edge of a windshield and/or rear window of a vehicle, and for applying a black metal primer onto the mating body flanges of the vehicle, in which an airless, cross cut-type flat pattern nozzle is employed to discharge such primer materials at pressures substantially below the normal pressures at which airless spray nozzles are operated to produce an atomized stream. A triangular-shaped liquid film emission of the primer materials is produced by such an airless spray nozzle, operated at low pressures, which forms a well defined pattern on both the windshield and the associated body flanges without splashing or overspray onto the surrounding surfaces.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
142 words
The method of applying liquid primer material onto the body flange of a vehicle in preparation for attachment to a section of glass, comprising: supplying the liquid primer material to an airless nozzle means; controlling the supply pressure of the liquid primer material to the nozzle means such that a liquid film emission is discharged from the nozzle means which is substantially free of atomized particles of liquid primer material; positioning the body flange of the vehicle in the path of the liquid film emission discharged from the nozzle means; producing relative movement between the nozzle means and the body flange of the vehicle to obtain a uniform, splash-free coating of the liquid primer material on a predetermined area of the body flange while substantially avoiding the application of the liquid primer material outside of the predetermined area of the body flange.
Claim 2
Independent Claim
142 words
The method of applying liquid primer material onto the body flange of a vehicle in preparation for attachment to a section of glass, comprising: supplying the liquid primer material to an airless nozzle means; controlling the supply pressure of the liquid primer material to the nozzle means such that a liquid film emission is discharged from the nozzle means which is substantially free of atomized particles of liquid primer material; positioning the body flange of the vehicle in the path of the liquid film emission discharged from the nozzle means; producing relative movement between the nozzle means and the body flange of the vehicle to obtain a uniform, splash-free coating of the liquid primer material on a predetermined area of the body flange while substantially avoiding the application of the liquid primer material outside of the predetermined area of the body flange.
Claim 3
Dependent Claim
33 words
The method of claim 1 in which said step of supplying the liquid primer material comprises supplying a liquid primer material having a viscosity in the range of about 20 to 40 cps.
Claim 4
Dependent Claim
37 words
The method of claim 2 in which said step of controlling the supply pressure comprises supplying the liquid primer material at a pressure in the range of the equivalent of about 1.41 to 2.11 Kg/cm 2 .
Claim 5
Dependent Claim
39 words
The method of claim 2 in which said step of positioning the body flange comprises positioning the body flange at a distance from said nozzle means in the range of the equivalent of about 10 mm to 20 mm.
