Title:
2方向に曲げられるガラスパネルの曲げ及び強化または熱強化のための方法および装置
Document Type and Number:
Japanese Patent JP4413194
Kind Code:
B2
Abstract:
The invention relates to a method and apparatus for bending and tempering or heat-strengthening a bidirecdonally curved glass panel. A heated glass panel is curved in a main bending direction parallel to the advancing direction and in a sagging direction transversely to the advancing direction. Curving in the sagging direction is performed by bending conveyor rolls, the bending of which is effected by turning lever elements bearing-mounted for free rotation on the ends of the conveyor rolls. Between the outer ends of the lever elements is a push rod, whose length is quickly variable by means of an actuator.
