Method of and apparatus for bending and tempering glass sheets

TLDR
In this paper, an array of conveyor rollers in a glass sheet bending and tempering section is adapted to be curved around an axis of curvature transverse to the traveling direction in a manner that, beginning from a horizontal plane, the plane of a roller line curves with a continuously diminishing radius of curvatures until the final radius is reached.
Abstract
The invention relates to a method of bending a glass sheet to be tempered as well as to a glass sheets bending and tempering apparatus. An array of conveyor rollers in a glass sheets bending and tempering section is adapted to be curved around an axis of curvature transverse to the traveling direction in a manner that, beginning from a horizontal plane, the plane of a roller line curves with a continuously diminishing radius of curvature until the final radius of curvature is reached. During the curving process, the tangent of the mid-portion of a curved conveyor section is maintained substantially in a horizontal plane. Thus, each point in a glass sheet curves substantially at the same rate over the entire glass sheet area and, hence, local rapid deformations do not occur. During the curving process, a glass sheet is maintained in motion by means of the rollers of a curved roller conveyor.

Method and apparatus for shaping sheet material

TL;DR: In this paper, a method and apparatus for bending sheets in the plastic state, such as sheets of glass at their softening temperature, in two directions is described, consisting of a first bed of arcuate rods which can be positioned to impart a transverse curvature to the sheet, and a second bed of arcsule rods which are positioned to produce a longitudinal curvature on the sheet.
