Abstract

LA REJILLA CONSTA DE DOS JUEGOS SUJETOS CON TIRANTES DE PLACAS. CADA JUEGO ESTA CONSTITUIDO POR PLACAS (22,24) PARALELAS EN SI Y FIJADAS EN SUS EXTREMOS A UN CEÑIDOR CON FORMA DE CINTA QUE PRESENTA UNAS ALETAS SOBRE UNA ARISTA LONGITUDINAL, ESTANDO DESPROVISTO CADA DIEDRO DE LA CEÑIDOR DE ABERTURA. AL MENOS DOS DE LOS DIEDROS ESTAN TRUNCADOS EN RELACION A LAS PROLONGACIONES DE LAS CARAS PLANAS DEL CEÑIDOR Y UNIDOS A LAS ARISTAS DE DICHAS CARAS POR MEDIO DE BOLSAS (17) EN PENDIENTE HACIA EL INTERIOR DEL CEÑIDOR.
