ISO 8489-5:1995

Overview

ISO 8489-5:1995 is an international standard developed by the International Organization for Standardization (ISO) that specifies the key dimensions, tolerances, and designation protocols for cones used in textile machinery for cross winding. This part of ISO 8489 focuses specifically on cones with a half angle of 5° 57'. It provides manufacturers and users of textile winding equipment with detailed guidelines to ensure consistent quality, interoperability, and precision in the production and use of these cones.

The standard also offers directives regarding the characteristics of cones, as well as the control and measurement of cone diameters and lengths, facilitating accurate manufacturing and quality control.

Key Topics

• Dimensions and Tolerances
  Specifies the nominal sizes and permissible variations for critical cone dimensions such as large and small diameters, length, and wall thickness. Dimensions are given in millimeters with defined tolerance limits to ensure compatibility in winding applications.

• Cone Types
  Defines two main types of cones:

  • Type A: Open-ended cone
  • Type B: Cone with rolled-in top
    Both types include optional design features such as tailing grooves and notches for yarn tails.

• Material and Surface Treatment
  Manufacturers are required to specify cone materials (commonly paper or plastic) and surface treatments (untreated, impregnated, or lacquered). These factors influence cone durability and compatibility with different yarn types.

• Quality Control and Gauging
  Details requirements for the use of gauges to verify cone dimensions and tolerances. Specific gauge dimensions ensure conformity to the standard, assisting quality assurance in production and receiving inspections.

• Designation System
  Provides a clear, standardized method to designate cones by specifying:

  • The word "Cone"
  • ISO 8489-5 reference
  • Cone type (A or B)
  • Large inner diameter (in millimeters)
  • Length of the cone (in millimeters)
    Example: "Cone ISO 8489-5 - A 68 x 170"

Applications

ISO 8489-5:1995 is essential in the textile industry, particularly for manufacturers and suppliers of textile winding machinery and accessories. Its practical applications include:

• Cross Winding Operations
  Ensures consistent cone geometry for cross winding processes, which improve yarn quality and reduce defects during fabric manufacturing.

• Machine Compatibility
  Enables equipment manufacturers to design winding machines that accommodate standard-sized cones, facilitating smooth integration and interchangeability.

• Quality Assurance
  Provides textile producers and cone manufacturers with standardized inspection methods to maintain dimensional accuracy and performance reliability.

• Material Management
  Helps determine suitable cone materials and treatments tailored to the type of yarn and winding conditions, enhancing production efficiency.

Related Standards

ISO 8489-5 forms part of the broader ISO 8489 series on cones for cross winding, which includes:

• ISO 8489-1: Recommended main dimensions for cones
• ISO 8489-2: Dimensions, tolerances, and designation for cones with half angle 3° 30'
• ISO 8489-3: Dimensions, tolerances, and designation for cones with half angle 4° 20'
• ISO 8489-4: Dimensions, tolerances, and designation for cones with half angle 4° 20' used in dyeing

Additionally, it references:

• ISO 286-1: System of limits and fits – Bases of tolerances, deviations, and fits

Compliance with these related standards supports harmonization across textile machinery components and helps maintain global quality benchmarks in the textile manufacturing industry.
