Abstract

Aparato para modelar curvaturas de ángulo relativamente agudo en hojas de vidriocaracterizado porque comprendiendo un bastidorun molde de curvado del tipo de contorno soportando sobre dicho bastidor y que tiene una superficie de configuración formada en élmedios eléctricamente conductores en el bastidorque incluye conjuntos de contacto eléctrico que pueden ponerse en contacto con líneas eléctricamente conductores formadas en una hoja de vidrio soportada sobre el moldecada uno de los conjuntos de contactos comprende un par de dedos espaciados desviados el uno hacia el otro para establecer un contacto de agarre o sujeción contra superficies opuestas de la hoja de vidrioestando por lo menos un elemento de contacto eléctrico asegurado a uno de los dedos y que entra en contacto con una de las líneas eléctricamente conductoras.
