Abstract
The invention concerns a method which consists in: pre-positioning, in a housing ( ) of a flange ( ), a bucket ( ) supported by part ( ) of its outer surface ( ) against an edge ( ) of the housing ( ) providing a space (E′) between the convex surface ( B) of the outer radial part ( B) of the bucket ( ) and said edge ( ); producing an articulated linkage ( ) of the bucket ( ) on the rim ( ) and/or the flange ( ) on the inside ( A) of the bucket ( ); exerting on the outer radial part ( B) of the bucket ( ) a first calibrated force to bring it closer to the edge ( ); determining the distance (e) between said outer radial part ( B) and said edge ( ) under said force; slackening said force; arranging, between said outer radial part ( B) and said edge ( ), a wedge ( ) having a thickness substantially equal to said distance (e); and exerting on the outer radial part ( B) of the bucket a second force (F ) to bringing it closer to the edge and maintaining said second force (F ) which has an intensity not less than that of the first force.
