Abstract
The present invention relates to a method for producing a reinforcement for a composite component, said reinforcement including superposed plies of thread, according to which method: PA1 straight portions of thread are laid down on a support; and PA1 all the superposed plies are consolidated by stitching, without knotting, a continuous thread. According to the invention: PA1 said straight portions of thread (4, 5) are laid down by means of a needle, with respect to which the continuous thread (F), of which each of said portions forms part, can slide, said needle being capable of moving relative to said support (6), pulling tight the straight portion of thread (4, 5) above the latter, over an extent equal to the length of said straight portion of thread; and PA1 said straight portions of thread (4, 5) are fixed by stitching, without knotting, at least one of the ends (4a, 4b; 5a, 5b) of each of said portions of thread into said support (6) using said needle.
