ISO 5234:2005

Overview

ISO 5234:2005 - "Textile machinery and accessories - Metallic card clothing - Definitions of dimensions, types and mounting" is an international standard that defines the geometry, tooth forms and mounting methods for saw‑tooth wire used in metallic card clothing for carding machines. Published by ISO (second edition, 2005), the document standardizes cross‑sections, pitch and blade characteristics, mounting arrangements and the dimensional terminology needed to specify and compare card clothing components.

Key topics

• Scope and purpose: establishes consistent definitions for saw‑tooth wire used in metallic card clothing with various cross‑sections and tooth forms.
• Cross‑sections: drawings and definitions for wires intended for mounting on grooved rollers or on the surface of ungrooved rollers (including normal rib and V‑type interlocking ribs).
• Tooth forms and orientation: illustrated tooth profiles (diamond point, extended pitch, Morel, flat top, pointed curved back, curved back with flat top), and left‑hand/right‑hand tooth orientation.
• Angles and blade geometry: standardized front angles and blade tip/root definitions to classify wire cutting geometry.
• Types and dimensions: normative Annex A contains tables (A.1–A.4) and figures that define terms such as total wire height, rib height, rib width, blade root and tip widths, and pitch width.
• Mounting methods: recommended methods for mounting wire sections on ungrooved and grooved rollers, single and multiple wire windings, and dimensional references for installation.
• Illustrations and references: numerous figures (Figures 1–20) illustrate wire profiles, mounting arrangements and winding examples to ensure correct interpretation.

Applications and who uses it

ISO 5234:2005 is used across the textile and engineering supply chain to ensure compatibility, safety and performance of carding components:

• Card clothing manufacturers - to design and produce saw‑tooth wires that conform to international dimensional definitions.
• Textile machinery builders and designers - to select appropriate wire types and mounting methods for new machines.
• Maintenance teams and mill engineers - to order replacements, verify correct mounting and ensure consistent carding performance.
• Procurement and quality control - to specify acceptance criteria and ensure interchangeability between suppliers.
• Standards committees and testing labs - for reference when measuring and reporting wire geometry.

Related standards

• ISO 9903‑1 and ISO 9903‑2 - referenced for main dimensions of wire profiles.
• Prepared by ISO/TC 72 (Textile machinery) - second edition replaces ISO 5234:1980.
