Abstract: Turbomachine member ring supports extending over sectors of a circle can be constructed from at least one thick flat metal sheet that is curved and welded to form a cylindrical shroud and then formed by pressing into a conical shroud, the outer face of which is machined in order to shape the profile of a mounting rail therein, and the shroud is sectioned in order to divide it into the sectors. The supports have better cohesion and the manufacture thereof is simple and reliable compared with traditional manufacture using bossing of thin metal sheets for joining together the main portions of the supports. The application also relates to a use with stator rings of a turbomachine member that are provided with an abradable lining.
