Abstract

LA INVENCION TRATA DE UN APARATO NO-TORCEDURA ("NTA") Y DEL METODO DE FABRICACION DE LA BARRA DE REFUERZO DE ACERO. LA UTILIZACION DE ESTE METODO HACE POSIBLE QUE LAS BARRAS DE REFUERZO DE ACERO SE FABRIQUEN CON MAYOR RAPIDEZ Y PRECISION QUE CON LOS METODOS TRADICIONALES. EL METODO NTA EMPLEA NUMEROSOS PIES (13-18), ESTANDO LOS DOS PRIMEROS PIES (13, 14) ALINEADOS CON LOS ARBOLES DE LOS ROLLOS ABARCANDO LOS ROLLOS OFFSET 45 DE UN PLANO PREDETERMINADO Y 90 TERCER Y CUARTO PIE (15, 16) ESTAN ALINEADOS CON LOS ARBOLES DE LOS ROLLOS PERPENDICULARES O PARALELOS AL PLANO PREDETERMINADO Y DIVIDEN LA BARRA UNICA EN VARIAS BARRAS. LOS PIES RESTANTES (17, 18, 17'', 18'') ESTAN COLOCADOS EN DOS LINEAS DE PIES POR LO MENOS, YA SEA CON LA PRIMERA DE CADA PIE EN LAS LINEAS ALINEADAS CON LOS LADOS DE SUS ROLLOS OFFSET 45 CCION, OPUESTA A LA PRIMERA DIRECCION, AL PLANO PREDETERMINADO, O CON LA PRIMERA Y SEGUNDA DE CADA PIE EN LAS LINEAS PARALELAS ALINEADAS CON LOS LADOS DE SUS ROLLOS OFFSET POR 90 OR 0
