Abstract

EN EL CURVADO DENTRO DE UN PLANO DE CURVATURA DE UN TUBO MULTIPLE (6) QUE TIENE UNA PLURALIDAD DE COMPARTIMIENTOS (7, 8) QUE SE EXTIENDEN TOCANDOSE EN LA DIRECCION LONGITUDINAL DEL TUBO, UNA POSICION DE DOBLADO SE MUEVE PROGRESIVAMENTE A LO LARGO DEL TUBO, Y DURANTE EL DOBLADO UN MANDRIL (12, 13) ESTA SITUADO EN EL INTERIOR DE CADA UNO DE LOS CITADOS COMPARTIMIENTOS EN LA POSCION DE DOBLADO. PARA MEJORAR EL CONTROL DE LA FORMA DEL TUBO, DURANTE AL MENOS PARTE DEL DOBLADO, LA POSICION DE AL MENOS UNO DE LOS MANDRILES (12, 13) CON RELACION AL TUBO EN LA POSICION DE DOBLADO VARIA CON DEPENDENCIA DE AL MENOS UN PARAMETRO DEL DOBLADO. AL MENOS UNO DE LOS CITADOS MANDRILES (12, 13) PUEDE SER LIBRE DE MOVERSE, BAJO LA RESTRICCION DE UNA FUERZA ELASTICA, EN LA DIRECCION LONGITUDINAL DEL TUBO
