Abstract
The present invention relates to a stitching head, which can be used in a machine for producing a reinforcement in the form of a sheet for a composite component formed by said reinforcement embedded in a cured matrix, said reinforcement comprising superposed plies of thread through which passes a consolidating thread, said head including a support carrying, on the one hand, means of linkage to the machine and, on the other hand, a needle as well as means for guiding the consolidating thread right to said needle. According to the invention, said stitching head (P) includes, associated with said needle (33), a device (43, 50) for compacting said superposed plies of thread.
