MECHANICAL METHODS OR APPARATUS IN THE MANUFACTURE OF ARTIFICIAL FILAMENTS, THREADS, FIBRES, BRISTLES OR RIBBONS

**Definition:** This place covers:

Mechanical methods and apparatus for the manufacture of artificial fibres and filaments.

It does also cover the physical and mechanical treatment of fibres and filaments during their production, e.g. before winding (after production: D01G , D02 ).

**Limiting references (this place does not cover):** - Working or processing of metal wire -> B21F - Production of metallic filaments -> B22D11/00 , B22F1/06 - Production of glass fibres -> C03B37/00 - Production of ceramic fibres -> C04B35/62227 - Apparatus specially adapted for the manufacture of carbon filaments are classified -> D01F9/00 - Processes starting from pre-made fibres or filaments, such as the production of yarns from single filaments -> D02G , D02J

**Glossary:** - Fibre: a relatively-short, elongated member of natural or artificial material; - Filament: an endless or quasi-endless, elongated member of natural or artificial material; - Thread: an assembly of yarns or filaments, usually produced by twisting. - Yarn: a unitary assembly of fibres, usually produced by spinning;
