ISO 8489-4:1995

Overview

ISO 8489-4:1995 - "Textile machinery and accessories - Cones for cross winding - Part 4" - specifies the dimensions, tolerances and designation of cones for cross winding used specifically for dyeing, with a cone half angle of 4°20'. The standard also gives directives on cone characteristics (materials, surface treatment, perforation) and on inspection methods for cone diameters and length.

Key topics and technical requirements

• Scope: Cones for cross winding intended for dyeing operations, defined by a half‑angle of 4°20'.
• Main dimensions and tolerances: Nominal internal large diameter and cone length are specified and controlled; tolerances on these dimensions limit deviations of the half‑angle and ensure interchangeability for dyeing processes. (Exact dimensional tables are provided in the standard.)
• Designation rule: Cones are designated using the format:
  Cône ISO 8489-4 - [large internal diameter] x [length]
  Example: Cône ISO 8489-4 - 59 x 170
• Material and construction characteristics: Manufacturer must specify material (metal, suitable plastics, or impregnated/varnished paper resistant to boiling), wall thickness (appropriate to yarn type), surface treatment, and number/position/size of perforations.
• Minimum distances: Minimum distance from cone ends to nearest holes: 16 mm + 0.5 mm.
• Control and gauging:
  • Conical gauge: edges of the cone must fall between tolerance marks when seated on the gauge. Gauge diameters have a tolerance class js6 (see ISO 286‑1:1988).
  • Length measurement: use an appropriate length measuring instrument (e.g., calipers); the conical gauge is not suitable for length control.

Applications and users

ISO 8489-4:1995 is practical for:

• Cone manufacturers - to produce cones that meet standardized dimensions and are fit for dyeing processes.
• Textile machinery designers and OEMs - to ensure compatibility of winding/dyeing equipment with standardized cones.
• Quality control laboratories and production managers - to inspect cone diameters, lengths and ensure conformity during procurement or incoming inspection.
• Dye houses and textile converters - to select cones that guarantee uniform winding and reliable dyeing performance.
