20020116950, Aug 29, 2002

Filed:

Sep 18, 2001

Appl. No.:

09/955795

Inventors:

Thomas Dunifon - Whitehouse OH, US
Jennifer Wolfe - Curtice OH, US

International Classification:

C03B023/03

US Classification:

065/106000, 065/273000

Abstract:

An improved female mold is used in conjunction with a heated male mold for press bending glass products, such as vehicle windshields. The female mold is made of a material having thermal expansion properties equivalent to those of the corresponding male mold, preferably ceramic and most preferably the same ceramic material as the male mold. Additionally, the female mold is preferably heated so that the glass sheet to be press bent is contacted by heated surfaces on both sides.

Inventors:

Thomas Dunifon - Whitehouse OH, US
Jennifer Wolfe - Curtice OH, US

International Classification:

C03B023/03

US Classification:

065/106000, 065/273000, 264/225000

Abstract:

An improved male mold for press bending sheets of glass includes, as heating elements, heating wires which are disposed in the male mold in a manner which conforms to the outer surface of the male mold. These heating wires provide a more uniform temperature profile over the pressing surface of the male mold, thus more uniformly heating sheets of glass. Additionally, a method is provided of making a male mold for press bending sheets of glass with such conformal heating elements.

International Classification:

C03B 23023

US Classification:

65104

Abstract:

A process and apparatus for conveying formed, heated glass sheets from a glass forming station, through a glass tempering station, to a lehr, utilizes a shuttle ring conforming in outline and elevation to the marginal edges of the glass sheet. The shuttle ring receives the glass sheet from the lower shaping mold, by the relative downward vertical movement of the lower shaping mold away from the upper shaping mold. The glass sheet thus deposited on and supported by the shuttle ring is transported through the tempering station to the lehr.
