APARELHO PARA FORMACAO DE CURVATURAS ANGULARES RELATIVAMENTE AGUDAS EM FOLHAS DE VIDRO

摘要

An apparatus for forming relatively sharp angled bends in a flat sheet of glass including a sectionalized gravity mold structure having electrical conducting means terminating in improved contact assemblies engageable with electrically conducting frit lines or paths formed on a glass sheet. The contact assemblies are mounted on the mold structure for movement along with the glass sheet relative to the mold during bending and offer continuous positive clamping contact with the electro-frit circuitry at all times.
