摘要

Method and apparatus for bending and annealing or grinding thermal panel, the curved bidirectionally.The invention relates to a method and a device for bending and annealing or grinding thermal of a glass panel of two-way curved.A heated glass panel is curved in a direction parallel to the folding main feed direction and in a direction of bulging transversely to the feed direction.The curvature in the direction of bulging is performed by carrying rollers for folding (4) which is made by folding rotating elements of the lever (7) mounted on bearings for rotation livRe the ends of the carrying rollers.Between the ends of the elements of external lever (7) there is a control stem (8) whose length is variable by means of a fast actuator (9).
