Abstract

1392994 Circular fibres NOVIPRO 12 July 1972 [15 July 1971] 32568/72 Heading B5B [Also in Divisions D1 and D2] An extrusion-blown polypropylene tube of diameter 20 mm. and thickness 50 microns is transversely sectioned at 0À5 mm. intervals to give annular fibres, i.e. endless fibres in the form of closed loops or rings having a 50 x 500 micron cross-section. The annular fibres are formed into a non-woven fabric (see Divisions D1-D2).
