Overview
ISO 476:1982 - Textile machinery and accessories - Pirn winding machines - Vocabulary defines standardized terminology for pirn winding machines and their accessories used in weaving preparatory machinery. First published 15 February 1982, this International Standard replaces ISO Recommendation R 476‑1966 and constitutes its technical revision. It establishes basic terms and corresponding definitions in the official ISO languages (English, French and Russian) and provides German and Italian equivalents in an informational annex.
Key topics
The standard focuses on consistent, unambiguous vocabulary relevant to pirn winding and associated equipment. Core topics include:
- Types of pirn winding machines: definitions for automatic, semi‑automatic and non‑automatic machines.
- Pirn winding head: single‑spindle and multiple‑spindle (multihead) assemblies and their function on winding machines or as weave‑machine attachments.
- Pirn location and feeding: terms for spindle mounting (on‑spindle, between points), and methods for transferring empty pirns to winding positions (manual vs automatic).
- Reserve formation: terminology for reserve or bunches at the pirn base or tip.
- Yarn handling elements: definitions for yarn guides, yarn‑guide traverse mechanisms (mechanical, hydraulic, electro‑mechanical/electronic) and devices for ensuring proper tension and guidance.
- Auxiliary devices: terms for automatic yarn cutting at pirn change, wind‑ratio mechanisms, and traverse‑displacement devices.
- Terminology context: scope limited to weaving preparatory machinery and the utilization of automatic pirn winding in contemporary textile production.
Applications and users
ISO 476:1982 is a practical reference for professionals who need consistent terminology across technical documents, specifications and communications:
- Manufacturers and designers of pirn winding machines and accessories - for product documentation, design specifications and interoperability.
- Technical writers and translators - to ensure accurate multilingual terminology (official ISO languages and annexed German/Italian equivalents).
- Procurement and quality assurance teams - to align purchasing specifications and acceptance criteria.
- Maintenance and production engineers - for clear identification of machine parts, functions and maintenance procedures.
- Standards committees, educators and researchers - as a baseline vocabulary for teaching, standards development and comparative studies.
