Abstract

M quina de fabricación de tubo corrugado espiralmente enrollado. Una m quina de fabricación de tubo corrugado espiralmente enrollado tiene rodillos (4, 5), interior y exterior, de unión de banda, con regiones de resalte diametralmente opuestas para definir un espacio de deformación rectangular. Una m quina para fabricación de tubo corrugado, mediante enrollamiento helicoidal de banda longitudinalmente corrugada, comprende: (a) un rodillo (5) exterior de unión de banda, con un perfil de corrugado que se acopla al perfil de corrugado de la banda (6); y (b) un rodillo (4) interior de unión de banda, con un perfil de corrugado mayor que el perfil de corrugado de la banda, teniendo los picos del corrugado el mismo radio de curvatura que los picos de corrugado de la banda, y teniendo los valles del corrugado un radio de curvatura ligeramente mayor que los valles del corrugado de la banda. En la región de los corrugados que se va a unir a la banda y a deformar, los dos rodillos tienen regiones salientes diametralmente opuestas que forman un espacio intermedio de deformación rectangular.
