ISO 5239:1980

Overview

ISO 5239:1980 - "Textile machinery and accessories - Winding - Basic terms" is an international vocabulary standard developed by ISO/TC 72. It defines the basic terminology used for the winding of yarns onto formers or other suitable devices by winding machines. The standard also explicitly applies to yarn‑like materials such as filaments and man‑made tapes, and its terms are intended for use across related textile processes (for example, spinning and twisting). The official text is in English, French and Russian, with informative German and Italian equivalents provided in annexes.

Key topics

The standard establishes clear definitions for core winding concepts and components to ensure consistent communication in design, manufacturing and testing of textile winding equipment. Primary terms covered include:

• Spindle - the rotating part of a winding machine on which yarn is wound (or a suitable device replacing the spindle).
• Former (support) - the object that supports the wound yarn (see ISO 1809 for former types).
• Wound yarn - yarn formed into a cylindrical, conical or other package shape.
• Wound package - the unit consisting of a former and the wound yarn (see also ISO 5238).
• Wrap / pitch / lead angle - geometric terms describing helix shape, distance between wrap crossings and the lead (guiding) angle used in package build.
• Traverse, stroke, cycle, stroke length - motion terms describing yarn‑guide movement (to and fro movements, reversal points and travel distance).

Notes and figures in the standard illustrate helix geometry (lead and crossing angles) and traverse mechanics, supporting correct interpretation of wrap, pitch and traverse parameters.

Applications

ISO 5239:1980 is practical for:

• Textile machinery manufacturers and designers aligning machine descriptions, drawings and specifications.
• Process engineers and production managers optimizing winding parameters and package geometry.
• Quality, testing and inspection teams standardizing terminology in reports and specifications.
• Technical writers, translators and standards committees ensuring consistent multilingual use of winding terms.
• Education and training programs in textile technology.

Using a common vocabulary reduces misinterpretation between suppliers, OEMs and mills and facilitates interoperability of equipment documentation, procurement and compliance activities.
