Abstract
A coating apparatus includes non-orthogonal coater geometry to improve coatings on a glass ribbon, and to improve yields of such coatings. The apparatus includes a first arrangement to move the ribbon along a first imaginary straight line through a coating zone provided in a glass forming chamber. The coater has a coating nozzle and an exhaust slot, each have a longitudinal axis. The coating nozzle directs coating vapors toward the coating zone, and the exhaust slot removes vapors from the coating zone. A second arrangement mounts the coater in spaced relation to the path with the coating nozzle and the exhaust slot facing the coating zone. A second imaginary straight line is normal to the longitudinal axis of the coating nozzle, and the first imaginary line and the second imaginary line subtend an angle in the range of greater than zero degrees to 90 degrees.
