Abstract
L'ailette, formée de façon connue, est courbée par rapport au plan perpendiculaire à l'axe de laminage du tube après détente préliminaire du tube et dressage de l'ailette. En cas de formage d'ailettes sur tube bimétallique, le tube extérieur est de plus serré contre le tube intérieur. L'outil servant à former les ailettes à un ensemble de rouleaux à courber l'ailette déjà formée, composé de rouleaux d'appui 5 et de dressage 7 entre lesquels, dans le cas de l'outil pour les tubes bimétalliques, il y a au moins un rouleau de brunissage 6.
