ISO 109:1982

Overview

ISO 109:1982 is an international standard established by the International Organization for Standardization (ISO) that specifies the working widths and related dimensional terminology for weaving machines used in the textile industry. This standard applies to a range of weaving machinery types, including those with or without shuttles such as projectile and rapier weaving machines. It replaces the previous ISO Recommendation R 109-1968 and provides a technical revision to ensure consistency and clarity in the designation and measurement of weaving machine widths.

Key Topics

• Working Width Definitions
  ISO 109:1982 clearly defines the key dimensional terms for weaving machines:

  • Maximum Working Width: The largest width of the warp sheet that can be woven within the reed, including auxiliary selvedges if needed.
  • Minimum Working Width: The smallest usable warp width within the reed configuration.
  • Reed Space: The maximum space available to accommodate the reed in the weaving machine.
  • Usable Width of Heald Frame: The portion of the heald frame rod available for stringing healds.

• Dimensional Intervals
  The standard recommends that maximum working widths begin at 800 mm and increase in intervals of 100 mm, with a suggested future step increment of 200 mm. This incremental system facilitates compatibility and standardization of machine components.

• Component Dimension Coordination
  To ensure operational efficiency, the dimensional attributes of critical weaving machine parts-such as the weaver’s beam, warp stop motion, heald frames, and cloth roller-must be designed in alignment with the specified maximum working width. This harmonization enables modular design and interchangeability within the machinery assembly.

Applications

ISO 109:1982 is essential for manufacturers, engineers, and quality assurance teams involved in the design, production, and maintenance of weaving machines. The standard offers practical benefits that include:

• Design Consistency
  Ensures equipment manufacturers produce weaving machines with standardized width dimensions, facilitating compatibility with various textile production lines.

• Interoperability
  Supports machinery upgrades and integration by providing clear guidance on component dimensions, which aids in selecting parts or retrofitting machines.

• Quality Control
  By following standard width definitions, textile producers can maintain consistent fabric quality and reduce production variability resulting from incorrect machine settings.

• Technical Communication
  Provides a common language for cross-border collaboration among textile machinery manufacturers, suppliers, and users, reducing misunderstandings during specification and procurement.

Related Standards

• ISO R 109-1968
  The original recommendation that ISO 109:1982 replaces and technically revises, focusing on weaving machine width terminology.

• ISO/TC 72
  The Technical Committee responsible for textile machinery standards, which develops related standards concerning weaving operations, machinery components, and auxiliary equipment.

• Other Textile Machinery Standards
  Standards covering loom safety, performance criteria, and control systems often complement ISO 109 by defining additional requirements linked to weaving machine operation and maintenance.
