Shaping Of Tube Ends By Bending Or Straightening

Abstract
Tubo rigidizado de enrollamiento helicoidal, caracterizado por el hecho de que la banda constituyente del helicoide estructural presenta, además del apestañado de borde para conformar el engatillado de empalme, un pliegue cerrado pinzado en el centro de la banda y según eje longitudinal y cuyo pinzado es proporcional al ancho de la misma para conformar un doble momento resistente a la flexión que, unido al producido por la nervadura propia del engatillado, proporciona una resistencia suficiente a pesar de aumentar el ancho de la banda matriz.
