Patent ID: 8672636

Claim:
Automatic method for manufacturing a stator or rotor blade preform for a turbine engine, comprising at least the following successive steps: a) a step for the helical braiding of a plurality of tubular braids ( 1 ) interlocking into one another, called nested braids, said step being conducted on braiding machines ( 2 ) placed in a row in a braiding direction; b) a step for flattening the nested braids ( 1 ); c) a step for stitching the nested braids ( 1 ) together in a direction perpendicular to the braiding direction; d) a step for winding the nested braids ( 1 ) on a transport mandrel ( 3 ); e) a step for cutting the nested braids ( 1 ) unwound from the transport mandrel ( 3 ), said cut being performed in a direction perpendicular to the braiding direction.
