Abstract
An edge-press molding element is part of a glass-bending tooling that includes a contoured-ring, gasket form factor. The edge-press molding element operates by self-weight bending a glass pane under a thermal load. The glass pane bends under molding conditions where a temperature differential of as low as 30° C. up to 100° C. is achieved between an edge of the glass pane and the center.
Claims13
A glass-bending tooling for bending glass in a direction, comprising:
- a contoured tooling rail;
- an edge-press molding element, wherein the edge-press molding element circumferentially follows a form factor, wherein the form factor comprises a thickness measured in the direction and a width being measured perpendicular to the direction, wherein the width is greater than the thickness, wherein the width of the edge-press molding element is greater than a width of the contoured tooling rail measured perpendicular to the direction;
- and
- a cushion layer on a contact surface of the edge-press molding element, wherein the edge-press molding element is configured to press the contoured tooling rail via its own self weight, wherein edge-press molding element comprises a body of material that extends inward from a periphery thereof by the width.
