PCT No. PCT/FI95/00585 Sec. 371 Date Jul. 1, 1997 Sec. 102(e) Date Jul. 1, 1997 PCT Filed Oct. 24, 1995 PCT Pub. No. WO96/13465 PCT Pub. Date May 9, 1996A method and apparatus for adjusting a quench head for glass tempering is provided. The quench head comprises at two nozzle blocks, each one of the nozzle blocks comprising at least one nozzle for directing the flow of a substance in gaseous phase to impinge onto the surface of the glass at certain areas. The nozzle blocks are supported on a frame to form at least one row of nozzle blocks. The frame comprises means for adjusting the tempering conditions effected to the surface of the glass to follow the shape of the surface of the glass. The directions of the flows of the substance in gaseous phase is adjusted such that the distance between the areas where a substance impinges the surface of a glass, between at least one pair of adjacent nozzle blocks and at least one row is kept substantially constant, regardless of the shape of the glass.
