Overview - ISO 18600:2015 (Web roller cards, terms and definitions)
ISO 18600:2015 is an ISO International Standard that defines the terminology for web roller cards - machines that form unconsolidated non-woven web from staple fibres using a web-forming method. Published in October 2015 and developed by ISO/TC 72 (Textile machinery and accessories), the standard provides consistent, well‑illustrated definitions of machine parts, width dimensions and technological terms used across web roller card design, manufacture and operation.
Key topics and technical scope
The standard is a terminology document (terms and definitions) and covers:
- Basic terms: e.g., web roller card, web, work flow direction, entry/delivery side, left/right side.
- Width dimensions: definitions for working width, cylinder width, width of carding wire, and bearing centre distance, with explanatory figures.
- Technological terms: parameters such as draft (ratio of delivery to entry speed) and distribution (circumferential speed relationship), including the formulas used to express them.
- Machine components: structured definitions and illustrations for machine sub‑assemblies and rollers, including:
- Feed unit: feed plate, feed roller, taker‑in roller
- Breast unit: breast cylinder, worker roller, stripper roller
- Transfer unit and wind rollers
- Main cylinder unit: main cylinder, worker roller, stripper, fibre guiding element
- Take‑off unit: random roller, doffer, condensing roller, take‑off roller, take‑off combing device, web transport conveyor
Practical applications - who uses ISO 18600:2015
This terminology standard is valuable for:
- Manufacturers and designers of web roller cards and related non‑woven machinery - for consistent part naming and documentation.
- Procurement and specification writers - to create unambiguous purchase specifications and acceptance criteria.
- Production and maintenance engineers - to standardize maintenance instructions, spare parts lists and training materials.
- Standards committees, test labs and educators - as a reference for technical documents, training and conformity activities.
Using ISO 18600:2015 improves communication across supply chains, reduces ambiguity in technical drawings and manuals, and supports interoperability between equipment and processes.
