Embodiment Construction

[0012] In the arrangement according to the invention, a glass plate 1 (plate glass plate) is led into a quenching zone 3 by a heating zone 2, for example formed by a series of ceramic nozzles from which heated gas (air) emerges, said The quenching zone consists of at least one pair of nozzles 4 arranged on both sides of the transport track 5 of the glass disk 1 to be hardened and from which cooling gas (air) emerges. The nozzles 4 arranged in the quenching zone are adjustable transversely to the transport path 5 (arrow 6 ), so that the distance of the nozzles 4 from one another can be adapted to the thickness of the glass disk 1 to be hardened.

[0013] Between the heating zone 2 formed on the one hand by ceramic nozzles and the quench zone 3 formed by at least one pair of quench nozzles 4 on the other hand, according to the invention at least two mutually opposite nozzles 7 (supporting nozzles) are arranged, The gaseous medium (air) is ejected from these nozzles towards the t...

Abstract

For a device for tempering flat glass, the glass panes (1) are supported by air bearings on both sides between a heating zone (2) and a quenching zone (3). The nozzles (7), from which pressurized air for forming the air bearings escapes, are placed at an angle in such a way that the nozzles point away from the heating zone (2) and toward the quenching zone (3), whereby cooled air is prevented from flowing from the quenching zone (3) toward the heating zone (2).

Description

technical field [0001] The invention relates to a method for hardening sheet glass and a device capable of hardening sheet glass. Background technique [0002] Hardening of the sheet glass is carried out by heating the sheet glass above the hardening temperature (generally about 650° C.) and then quenching to generate stress in the sheet glass that hardens the sheet glass. [0003] Numerous devices are known for hardening sheet glass, in which there is always the problem of separating the heating zone from the quenching or cooling zone. Contents of the invention [0004] The purpose of the invention is to propose a simple and effective solution. [0005] This object is achieved according to the invention by a method having the features of claim 1 . [0006] The object according to the invention is also achieved by a device which has the features of the independent claim for the device. [0007] Preferred and advantageous refinements of the invention are the subject matt...
