ISO 9473-2:2006

Overview

ISO 9473-2:2006 is an international standard published by the International Organization for Standardization (ISO) that specifies the dimensions and designation of hardened strip steel used in the manufacture of dents for reeds in textile machinery. This standard forms Part 2 of the ISO 9473 series, focusing specifically on hardened strip steel as opposed to cold-rolled steel covered in Part 1. It aligns with related standards ISO 366-1, ISO 366-2, ISO 366-3, and ISO 366-4, which define dimensions and designations for various types of reeds used in textile production.

This technical specification is essential for ensuring consistent quality, dimensional accuracy, and material properties of strip steel used in textile combing and weaving accessories, notably the dents-small, sharp teeth in reeds responsible for separating and aligning warp threads.

Key Topics

• Scope and Application
  ISO 9473-2 defines nominal dimensions, tolerances, and material requirements for hardened strip steel manufactured to produce dents of reeds. It supports the fabrication of precise textile components integral to machinery performance.

• Dimensions and Tolerances
  The standard provides detailed dimensional data including width (b), thickness (s), and permissible tolerances to ensure proper fit and function in the textile machinery. Dimensions are expressed in millimeters with exact tolerances to facilitate interchangeability and performance consistency.

• Material Specifications
  The strip steel must be hardened to achieve the necessary durability and resistance to wear. The choice of steel type, whether non-alloy or stainless steel, is determined by mutual agreement between supplier and purchaser, emphasizing flexibility while maintaining quality standards.

• Designation System
  ISO 9473-2 mandates a clear designation format including:

  • The term "Feuillard d'acier trempé" (Hardened strip steel)
  • Steel type (non-alloy or stainless)
  • Reference to ISO 9473-2
  • Width and thickness measurements
    This standard designation ensures clarity and traceability of materials used in textile machinery production.

• Edge and Dent Quality
  Edges of the strip steel dents should be rounded to prevent damage to threads and enhance the durability of reeds. This maintains fabric quality and reduces machinery downtime.

Applications

• Textile Machinery Manufacturing
  Producers of weaving equipment use hardened strip steel compliant with ISO 9473-2 to manufacture dents of reeds, critical for separating warp threads during weaving and ensuring fabric consistency.

• Quality Control in Textile Accessory Production
  Adhering to this standard enables manufacturers and buyers to specify and verify the quality and dimensional accuracy of steel strips used in reed production, facilitating high-quality textile machine operation.

• Replacement and Maintenance of Textile Equipment
  Operators of weaving and combing machines benefit from standardized steel strip dimensions and quality, easing maintenance, repair, and replacement of worn or damaged dents.

• Research and Development in Textile Engineering
  Innovation in textile machinery components often requires material specifications that meet standardized requirements for hardness, dimensions, and durability as outlined by ISO 9473-2.
