Abstract:
A glass sheet quench unit for quenching formed glass sheets, comprising:a plenum housing defining a quench plenum to which pressurized gas is supplied; anda plurality of nozzle feed rows extending from the plenum housing in a spaced relationship from each other, each nozzle feed row having a pair of generally planar sides, the planar sides of the nozzle feed rows having inner extremities mounted by the plenum housing and also having distal extremities with curved shapes along a longitudinal axis, each nozzle feed row having an elongated nozzle cap that is curved in a direction along the longitudinal axis and is secured to the curved distal extremities of its planar sides, and the nozzle cap of each nozzle feed row having a curved cross section along its length perpendicular to the longitudinal axis and having nozzle openings for providing quench gas jets that define a uniformly repeating gas jet impingement pattern providing uniformly repeating quench cells distributed over a formed glass sheet to be quenched to provide uniform quenching.
