Abstract
Method of manufacturing a hollow blade (1) for a turbomachine in which the blade (1) is made from a preform (14) obtained from external primary parts (28, 30). In order to reduce costs, the root part (2) of the blade is formed from spare material (34) entirely located on only one of the two external primary parts of the preform (14).
