Method of and apparatus for cooling and tempering a glass plate |
摘要 |
A glass plate is cooled and strengthened by placing the glass plate on a cooling ring in a substantially horizontal state and jetting out cooling air at upper and lower sides of the glass plate by upper and lower cooling air jetting-out devices arranged at the upper and lower sides of glass plate. The pressure of cooling air jetting out from the lower side of the glass plate is higher than that from the upper side to thereby raise the glass plate against a contact ring located below the upper jetting out device.
