Abstract

1372223 Leno fabrics FONDERIE ET ATELIERS DE MERSCH SA and CLOUTH GUMMIWERKE AG 22 Dec 1971 [23 Dec 1970] 59663/71 Heading D1K [Also in Division B5] A fabric suitable for incorporation in a diaphragm (see Division B5) comprises warp yarns 7 which are in pairs and twisted once about each other between adjacent single weft yarns 6 (see Fig. 2). In Fig. 3 the single weft yarns are replaced by pairs of threads twisted together. The yarns may be of natural or artificial fibres and may be reinforced with metal threads, metal braids or synthetic filaments.
