Overview
ISO 10787-3:1994 is an international standard developed by the International Organization for Standardization (ISO) that specifies the dimensions for guides used in heald frames, which are components of textile machinery. Heald frames are essential parts of weaving machines, supporting and guiding the healds-wires or plates with eyes through which warp yarns pass. The guides play a critical role by providing supplemental guidance to the heald frames, ensuring precise and consistent fabric manufacture.
This standard is part 3 of the ISO 10787 series focused specifically on Textile machinery and accessories – Heald frames. It aims to harmonize the dimensions and tolerances of these guides, facilitating interchangeability and compatibility between textile machinery components worldwide.
Key Topics
-
Scope and Purpose
Defines the dimensions and specifications for heald frame guides to ensure uniformity in design and manufacture.
-
Normative References
Includes references to related parts of ISO 10787 and ISO 2768-1, which provide coordinated dimensions for heald frame components and general tolerances for linear and angular dimensions respectively.
-
Dimensional Specifications
Detailed measurements such as the height, width, thickness, and distance between guide components are standardized, based on the pitch of the harness and frame sizes. These specifications are critical to the functionality and durability of the guides.
-
Designation Format
Provides guidelines on how to designate and order heald frame guides, including format for dimensions and reference to this part of the standard for clarity and traceability.
-
Tolerances and Manufacturing Precision
Specifies tolerant ranges and medium-class limits to ensure manufacturability without sacrificing quality or compatibility.
Applications
-
Textile Machinery Manufacturing
Manufacturers of weaving machines and their accessories use ISO 10787-3 to design and produce heald frame guides that are compatible across different equipment and models.
-
Machine Maintenance and Replacement
Facilitates sourcing and replacement of heald frame guides by providing standardized dimensions, helping to reduce downtime and maintain production efficiency in weaving operations.
-
Quality Assurance and Compliance
Helps quality control engineers verify that the manufactured guides meet international benchmarks, ensuring both safety and performance in textile production lines.
-
International Trade and Supply Chain
Supports global supply chains by establishing common dimensions, reducing technical barriers to trade of textile machinery parts.
Related Standards
-
ISO 10787-1:1994
Covers heald-carrying rod fixed to the frame stave by rod support and coordinated dimensions relevant to heald frames.
-
ISO 10787-2:1994
Specifies dimensions for heald-carrying rods fixed directly on the frame stave, complementing the guides detailed in Part 3.
-

Provides general tolerances for linear and angular dimensions without individual tolerance indications, applicable to parts specified under ISO 10787-3.
Practical Value
By adhering to ISO 10787-3:1994, manufacturers and users of textile machinery gain several advantages:
- Interchangeability: Ensures heald frame guides fit a variety of machines without customization.
- Consistency: Maintains product quality and machine performance through uniform component dimensions.
- Efficiency: Simplifies design processes by referencing standardized sizes and tolerances.
- Global Compatibility: Aligns with international textile industry requirements, facilitating export and collaboration.
- Supply Chain Simplification: Streamlines procurement and inventory management by standardizing part specifications.
