Abstract

Método para la producción de tubos por arrollamiento helicoidal con costura engrapada, a partir de un fleje metálico (12) que tiene zonas de borde longitudinales (16), comprendiendo las siguientes etapas: alimentar el fleje (12) a un cabezal de conformación (14); conformación del fleje (12) de forma helicoidal en el cabezal de conformación (14), de manera que las partes del borde (16) del fleje (12) conformado helicoidalmente se llevan a establecer contacto entre sí; engrapado las partes de los bordes en contacto (16) del fleje (12) para formar una costura engrapada (37) de arrollamiento helicoidal sobre un tubo (33) conformado en el cabezal de conformación (14); y alimentando el tubo (33) realizado por arrollamiento helicoidal con costura engrapada hacia afuera del cabezal de conformación (14); en el que unas deformaciones espaciadas (41) quedan dispuestas sobre la costura engrapada (37) a efectos de interconectar las partes de los bordes en contacto (16) del fleje (12) en la costura engrapada (37); caracterizado porque las deformaciones de interconexión están constituidas en forma de partes expansionadas (41) separadas entre sí a lo largo de la costura engrapada (37).Method for the production of tubes by helical winding with stapled seam, from a metal strip (12) that has longitudinal edge areas (16), comprising the following steps: feeding the strap (12) to a forming head (14 ); forming the strip (12) helically in the forming head (14), so that the parts of the edge (16) of the strip (12) helically formed are brought into contact with each other; stapling the parts of the contact edges (16) of the strip (12) to form a stapled seam (37) of helical winding on a tube (33) formed in the forming head (14); and feeding the tube (33) made by helical winding with seam stapled out of the forming head (14); wherein spaced deformations (41) are arranged on the stapled seam (37) in order to interconnect the parts of the contact edges (16) of the strip (12) in the stapled seam (37); characterized in that the interconnection deformations are constituted in the form of expanded parts (41) separated from each other along the stapled seam (37).
