Note(s) In this class: the following words are used with the meanings indicated: "fibre" means a relatively-short, elongated member of natural or artificial material. "filament" means an endless or quasi-endless, elongated member of natural or artificial material. "yarn" means a unitary assembly of fibres, usually produced by spinning. "thread" means an assembly of yarns or filaments, usually produced by twisting.
