Abstract

Method and apparatus for bending a glass pane in which undesirable elongations, localized deformations and residual stresses are eliminated by the advantageous use of such practices as preventing relative sliding movement between the glass pane and the bending apparatus and controlling the path followed by movable elements of the bending apparatus that accomplish the bending. The movable elements are mounted for motion about articulated axes, and the articulated axes themselves undergo constant dislocation during the bending.
