Abstract
UN METODO PARA PRODUCIR UN CUCHILLO DE VIDRIO EN EL QUE UNA PLACA DE VIDRIO PLANA (51) SE DIVIDE ROMPIENDO A LO LARGO DE UNA LINEA DE DIVISION (23) RAYADA EN LA PLACA MENCIONADA. LA PLACA SE COLOCA EN DOS BARRAS DE SOPORTE INFERIORES (9, 10), POSICIONADOS POR EL USO DE MEDIOS (7, 8) QUE COOPERAN CON LAS SUPERFICIES DE BORDE LATERALES DE LA PLACA DE VIDRIO, Y ESTA FIJADA POR MEDIO DE DOS BARRAS DE SOPORTE SUPERIORES (17, 18) HECHAS PARA ENGANCHAR LA CARA SUPERIOR DE LA PLACA MENCIONADA. CADA PAR DE BARRAS DE SOPORTE TIENE UNA LINEA DE SIMETRIA PERPENDICULAR A LA LINEA DE SIMETRIA DEL OTRO PAR, COINCIDIENDO UNA LINEA DE SIMETRIA CON EL PLANO DE DIVISION. ANTES DE ROMPER LA PLACA DE VIDRIO MOVIENDO LAS BARRAS DE SOPORTE UNA HACIA LA OTRA, LOS MEDIOS DE POSICIONAMIENTO (7, 8) ESTAN, AL MENOS PARCIALMENTE, DESENGANCHADOS DE LA PLACA DE VIDRIO, DE MANERA QUE SOLO LAS FUERZAS DERIVADAS DE LAS BARRAS DE SOPORTE ACTUEN SOBRE LA PLACA DE VIDRIO DURANTE EL ROMPIMIENTO DE LA MISMA.
