摘要： PURPOSE:To prevent the deformation (twist in the direction restoring the original shape) of bent glass at the time of producing the bent and tempered sheet glass by bending the sheet glass hung and held by hanger members after heating the sheet glass. CONSTITUTION:A truck mounted with the hanger members and a deformation preventive device 30 between the mounting plates of the hanger members are provided to prevent the backward travel of stretched turning arms 4, 4a.

摘要： PURPOSE:To stably and efficiently cool a hot thin plate glass especially of complicated shape with air and to temper the glass by making a cooling air to blow on plate glass to be tempered from nozzles connected to a compressor accompany air having developed impulse wave and regulating difference in pressure between the nozzles and nozzles coupled with a blower. CONSTITUTION:Cooling air from a cooling nozzles 5 arranged in a pair of air chambers 7 is blown on the surface of plate glass 1 heated to la strain point to temper the plate glass with air. In this case, the plate glass 1 is cooled with air by using both nozzles NC 11 which abruptly reduces pressure PC of cooling air by a compressor 9 from 2-8kg/cm to pressure of 1,000-4,000mm Aq and blows developed impulse wave and nozzles NB coupled with a blower 8. In the operation, correlation between pressure PB of the nozzles NB 12 and pressure PC of the nozzles NC 11 is required to satisfy 0

摘要： PURPOSE:To obtain reinforced glass plates of high flatness and smoothness without marks of hangers in high productivity by nipping a glass plate so that specifically processed plates are placed at least on one side between the glass plate and the hanger and effecting heat treatment. CONSTITUTION:A refractory material which has heat shock resistance, preferably thermal conductivity equal to or higher than glass, smaller thermal expansivity than glass and incompatibility to glass such as BN, SiC, ZrO2, platinum or another metal coated with ceramic is formed into a circular or triangular plate measuring 600-50mm size and 6-0.5mm thickness, bored a plurality of through-holes 6 of 0.5-3mm diameter and polished to a mirror-like surface of less than 10mu roughness. Then, a glass plate 2 is held with the end parts 4 of the hanger 1 so that the plate 5 is placed at least on one side between the glass plate 2 and the end parts 4 and tightened with holding bolts 3. The glass plate 2 is reinforced by heating over the strain point and cooling down rapidly.
