ISO 366-4:2005

Overview

ISO 366-4:2005 specifies the dimensions and designation of plastic-bound metal reeds used in weaving machines. Part 4 of the ISO 366 series, this second edition (2005) defines the dimensional rules, tolerance of perpendicularity for reed teeth, and a standardized naming format for plastic-bound metal reeds. The standard supports consistent manufacture, ordering and interchangeability of reeds across the textile industry.

Key topics and requirements

• Scope: Applies to metal reeds bound with plastic (plastic-bound metal reeds) for use on weaving machines.
• Dimensions: Specifies the key geometric parameters illustrated in the standard (see Figure 1), including:
  • Interior height (e) of the reed
  • Ligature thickness (d) (thickness of the plastic binding)
  • Tooth width (b) and tooth thickness (s)
  • Distance between teeth (t) and overall profile heights
• Dimension tables: Table 1 provides the standardized combinations of tooth widths (b), ligature thicknesses (d) and interior heights (e) that manufacturers and purchasers should use.
• Tolerances: Includes a tolerance for the perpendicularity of teeth relative to the reed base (see Figure 2).
• Designation rules: Specifies the required information and order for reed identification:
  • Mandatory elements: description, reference to ISO 366-4, interior height e (mm), ligature thickness d (mm), tooth width b (mm), and steel type (unalloyed, stainless or hardened).
  • Example designations from the standard:
    • Peigne métallique à ligature plastique ISO 366-4 - 80 × 8 × 4 - acier inoxydable
    • Peigne métallique à ligature plastique ISO 366-4 - 80 × 18 × 12 - acier trempé
• Interdependencies: Upper and lower ligature heights must comply with ISO 366-5 and be agreed upon between parties.

Applications and users

ISO 366-4 is intended for:

• Reed manufacturers and fabricators specifying production dimensions for plastic-bound metal reeds
• Textile machinery OEMs and weaving machine engineers ensuring component compatibility
• Purchasing/procurement teams standardizing orders and reducing specification errors
• Maintenance and spare-parts suppliers needing consistent replacement part identification
• Quality and metrology laboratories checking dimensional conformity

Practical benefits include improved interchangeability, reduced procurement ambiguity, easier spare-part matching, and clearer technical communication across suppliers and mills.
