Abstract
A device for tempering of a glazing by contact has two cooled compression plates and a device for cooling the peripheral surface of the glazing by air jets. The device intended to cool peripheral surfaces of the glazing consists of parallelepipedic blowing ramps placed between cooling and compression plates and in which are provided slots for the cooling air jets directed toward the peripheral surface of the glazing, and exhaust openings placed between the slots. The slots have a diameter at least equal to 1 mm and at most equal to the thickness of the glazings, and the exhaust openings having a cross section which is at least three times that of slots. The dimensions of the cooling and compression plates, as well as arrangement and/or width (B) of the ramps are such that a distance (A) between the orifices of outlet slots and peripheral surface of glazing which is opposite to it is at least two times and at most six times the diameter of the slots.
