YARNS; MECHANICAL FINISHING OF YARNS OR ROPES; WARPING OR BEAMING

|  | D02 |
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;
