Abstract

L'invention concerne un procédé et un appareil de revêtement de tuyaux d'acier. L'appareil est caractérisé en ce qu'il comprend une extrudeuse maintenue sur un châssis fixe, et une filière 4 supportée par ce châssis fixe de façon à pouvoir être entraînée alternativement par un mécanisme approprié 6 sur une course donnée dans la direction d'avance du tuyau d'acier A. Ainsi, quand la filière 4 est entraînée alternativement par ledit mécanisme, la vitesse relative du tuyau A par rapport à la filière peut être modifiée par intermittence, de même que, par consequent, la quantité de résine extrudée par l'intermédiaire d'un orifice cylindrique de sortie de la filière autour de la surface du tuyau. Application à la fabrication de tuyaux en forme de bambou.
