Overview
ISO 366-3:2009 is the International Standard that specifies the dimensions and designation of metal reeds with double-spring baulk for weaving machines. Published as Part 3 of the ISO 366 series, this 2009 (second) edition defines the measurable parameters and naming conventions needed to ensure interchangeability, correct specification and consistent manufacturing of metal reeds used in textile weaving.
Key topics and technical requirements
- Scope: Defines applicable metal reeds with double-spring baulk for weaving machines.
- Dimensions: Specifies the dimensional features illustrated in Figure 1 and listed in Table 1 of the standard, including:
- Total height (h) and inner height (e) of the reed
- Thickness of the reed baulk (d)
- Width of dents (b)
- End-piece width and overall/usable widths
- Tolerance requirement: Requires compliance with the specified tolerance of perpendicularity of dents relative to the reed base (illustrated in Figure 2).
- Designation format: Prescribes the information and order for naming reeds to ensure clear specification:
- “Metal reed with double-spring baulk”
- Reference to this part: ISO 366-3
- Inner height, e (mm)
- Total height, h (mm)
- Thickness of reed baulk, d (mm)
- Width of dents, b (mm)
- Steel type for dents (plain or stainless)
- Example:
Metal reed with double-spring baulk ISO 366-3 - 150 × 8 × 4 stainless steel
Applications and users
ISO 366-3 is practical for:
- Textile machinery manufacturers designing or specifying looms and reed assemblies.
- Reed and accessory suppliers producing metal reeds to standardized dimensions.
- Weaving mills and production engineers selecting compatible reeds for specific machines and fabrics.
- Quality, procurement and R&D teams ensuring interchangeability, accurate ordering, conformity testing and supplier communication.
Using this standard supports consistent reed fit, optimal fabric formation and reliable machine performance across suppliers and regions.
