A weld seam opening regulator for use in constructing cylindrical structures, including a frame, first and second wheels for riding on a first edge of a band of metal, a third wheel for riding on a first edge of a cylindrical portion of the structure, and a fourth wheel for riding on an inner surface of the cylindrical portion and maintaining a minimum weld spacing between the band and cylinder. Also, an adjustable bottom roller rides on a second edge of the metal band urges the metal band toward the cylindrical portion of the structure.

La présente invention a pour objet un dispositif permettant de régler l'écartement destiné au cordon de soudure dans la fabrication de structures cylindriques; le dispositif en question comporte un cadre-support, un premier et un deuxième galets en contact avec une première rive d'une bande de feuillard, un troisième galet en contact avec un premier bord de la portion cylindrique de la structure, et un quatrième galet venant en contact avec la surface interne de la portion cylindrique et servant à maintenir un écartement minimum aux fins de soudage du feuillard. De plus, un galet inférieur réglable est mis en contact avec un deuxième rebord du feuillard pour ramener celui-ci vers la portion cylindrique de la structure.
