Abstract: An apparatus for quenching a heated glass sheet includes a roll conveyor system for conveying the glass sheet in a direction of conveyance C generally along a plane of conveyance. The apparatus further has upper and lower sets of flow control members respectively located above and below the plane of conveyance. Each set includes multiple flow control members that each have multiple outlets for supplying quenching fluid for impingement with the glass sheet in inclined directions both upstream and downstream with respect to the direction of conveyance C. Moreover, each outlet provides a fluid flow path to the conveyed glass sheet. For each flow control member viewed in a direction generally transverse to the direction of conveyance C, the flow paths define a maximum angle of less than 75 degrees.
