Abstract

The invention relates to the manufacture of woven pieces made by multidirectional weaving. A woven piece comprises, along one of the directions of weaving, temporary vertical rods which must be replaced by yarns joined to form a strand. The apparatus comprises to this end an upper assembly for detecting the position of the rods of the piece, rotating step by step, and actuating a needle with opening eye which, on descending through the woven piece, chases the rods one by one and hooks, in a lower assembly, a loop of the lacing strand and returns it into the woven piece in place of the chase rod.
