Support ring for a hot glass pane during thermal prestressing

The invention relates to a support ring for a hot glass pane during thermal prestressing, in particular by blast air, with a support body and, arranged on the support body, bearing elements which form a bearing surface for the glass pane. The support body has a shape which is adapted to the outer contour of the glass pane and can be connected to a support frame with fastening elements. According to the invention, the bearing elements are designed as lamellae and connected positively to the support body. The side edges of the lamellae form in this case the bearing surface. Arranged between the lamellae are distance plates which form flow ducts and which can be pushed onto the support body. The bearing surface is inclined inwards and bears against the hot glass pane at an angle of inclination. ...
