Abstract
A glass sheet quench unit (,) and method for quenching formed glass sheets by quench gas jets (,) that define a uniformly repeating gas jet impingement pattern (,) that is an equilateral triangular pattern providing uniformly repeating quench cells (,) distributed over the formed glass sheet to be quenched as equilateral hexagonal quench cells. The resultant product is a formed and quenched glass sheet (G) that has oppositely facing surfaces between which glass stresses are uniformly distributed. A method for making the quench unit (,) is performed by initially forming nozzle openings (,) in an elongated nozzle strip (,′), thereafter forming the nozzle strip with a curved cross section, thereafter forming the nozzle strip with a curved shape along its elongated length to provide a curved nozzle cap, subsequently securing the curved nozzle cap to planar sides (,) of an associated nozzle feed row (,), and securing the sides (,) of the nozzle feed row to a plenum housing (,).
