PCT No. PCT/GB95/00703 Sec. 371 Date Sep. 30, 1996 Sec. 102(e) Date Sep. 30, 1996 PCT Filed Mar. 30, 1995 PCT Pub. No. WO95/27096 PCT Pub. Date Oct. 12, 1995A composite component is made up by laying pre-forms one on top of the other and tacking the pre-forms together at spaced, discrete locations by blind stitches which tack an upper pre-form layer to the one beneath it, using a stitching head. The stitching head 16 includes a curved needle 18 reciprocally movable in one plane and a looper 30 reciprocally movable in a transverse plane. In use the looper catches the thread from the needle as it emerges from the material and draws it into a loop around the next entry point for the needle.
