Abstract
The present application relates to a method for assembling a stator stage of a turbomachine, the stage having an inner ring, an outer ring, and vanes extending radially between the inner ring and the outer ring. The method includes at least the following essential step: applying at least one inflatable bladder against at least one opening between a vane and one of the inner ring and the outer ring on that face of the ring which is opposite the face for application of a sealing material, so as to form one or more retention surfaces for the sealing material. The present application also relates to an assembly device designed for implementing the method.
