Abstract

Un anillo de configuracion flexible para configurar láminas de cristal ablandadas con calor eleva una lámina de cristal ablandada con calor y la presiona contra la superficie de configuracion de un molde superior. A medida que el anillo de configuracion presiona la porcion del borde marginal de la lámina contra el molde superior, su superficie de configuracion se deforma para conformarse generalmente a una porcion correspondiente del molde superior. Un anillo de prensa entra en contacto posteriormente con el anillo de configuracion y lo presiona contra el molde superior para configurar adicionalmente la porcion del borde marginal de la lámina de cristal y asegura que el borde marginal se adapte completamente a la forma del molde superior.
