Abstract
In a method for manufacturing a hollow blade for a turbomachine, the blade is made from a preform derived from external primary parts. Each primary part comprising a root part is formed by flattening a blank cut out from a ring with a large diameter provided with a protuberance, in order to reduce costs.
