Removing fragments of fractured glass sheets during tempering

In a method of tempering glass sheets wherein a hot glass sheet is supported between upper and lower nozzle housings which apply cold tempering medium toward the opposite major surfaces of said glass sheet at a rate sufficient to establish at least a partial temper in the glass sheet, whereby sometimes said sheet is fractured to form fragments during said cooling step and said lower nozzle housing is pivoted to remove at least some of said fragments by sliding, the improvement comprising pivoting said lower nozzle housing beyond an orientation that requires said fragments to be removed by sliding to an orientation wherein fragments that do not slide off the lower nozzle housing during said pivoting to said orientation are free to drop by gravity without sliding from said lower nozzle housing when said lower nozzle housing pivots beyond said orientation.
