Date Apr. 20, 1989.The invention relates to the production of non-woven fabrics in which an array of weft threads is created and then combined with a substrate, which may in itself comprise a set of warp threads. In the method according to the invention, the array of weft threads is formed by traversing a weft carrier which has a plurality of weft guides, across the weft-space between two sets of weft retainers (300), (302). At the end of each traverse, the weft carrier is jogged, (that is to say moved in the warpwise direction) so that at the next traverse, it lays a further set of weft yarns across the weftspace, and the weft yarns are hooked around the weft retainers. The jogging motion (B) is such, that at each traverse of the weft carrier after the first traverse, some (1b), (2b), (3b), but not all of the laid weft yarns are interdigitated with weft yarns (1a), (2a), (3a) previously laid by the weft carrier or another weft carrier, the remaining weft yarns laid at that traverse being spaced from each other to permit a further set of weft yarns to be interdigitated with them on a subsequent traverse of the or another weft carrier.
