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, in which a dispenser is employed to discharge such primer materials in discrete streams or drops. The streams or drops impinge upon the surface of the glass such that any ricocheting or deflection of the material will remain within the area to be coated or is entrapped by a felt wick or pad without splashing or overspray onto the surrounding surfaces. An optical detector is employed to monitor the streams or drops of primer material dispensed.
Claims20
The method of dispensing discrete streams or drops of fluid coating material onto a glass substrate comprising the steps of:
- a) causing a wick means and a dispensing means to be moved relative to the glass;
- b) intermittently dispensing the fluid material from said dispenser means such that said streams or drops are propelled under pressure to impinge upon the substrate at an angle of incident which is less than 45.degree. while substantially avoiding the application of liquid coating material outside a portion of the substrate to be coated;
- and
- c) distributing the dispensed fluid material over the portion of the substrate to be coated by said wick means.
The method of preparing glass for attachment to a vehicle comprising the steps of:
- a) causing a dispensing means to be moved with respect to the glass;
- b) dispensing a liquid primer material to form a stream;
- c) producing a signal corresponding to the presence or absence of the dispensed stream at a point between the dispensing means and the glass;
- and
- d) uniformly distributing the dispensed liquid primer material over an area of the glass.
The method of preparing glass for attachment to a vehicle comprising the steps of:
- a) causing a dispensing means to be moved with respect to the glass;
- b) intermittently dispensing a liquid coating material to form discrete streams or drops;
- c) sensing the presence or absence of the discrete streams or drops dispensed from the dispenser, before the discrete streams or drops contact the glass, and producing a signal corresponding to the sensing;
- d) distributing the dispensed liquid coating material over an area of the glass;
- and
- e) comparing the signal with a reference.
