Overview
ISO 11111-4:2005 - Textile machinery - Safety requirements - Part 4: Yarn processing, cordage and rope manufacturing machinery - specifies significant hazards and corresponding safety requirements and/or measures for machinery used in yarn processing, cordage and rope manufacture. Intended to be used in conjunction with ISO 11111-1, this Type C standard covers machines for doubling, twisting, texturing, reeling, winding, ball winding, cordage and rope making, and braiding. It addresses mechanical, electrical and operational hazards and defines how to apply safeguarding, safety devices and information for safe use.
Key topics and technical requirements
- Scope and hazard identification: Lists significant hazards common to yarn processing and those specific to cordage and rope machinery; requires checking the specific machine against these hazards before use.
- General safety requirements: Refers to ISO 11111-1 for common safety principles (electrical equipment, control systems, starting/stopping, noise, fire, ergonomics, devices for special operation).
- Machine-type specific requirements: Separate sections for doubling/twisting/texturing, reeling/winding, ball winding, cordage/rope manufacturing and braiding - each covering typical risks and corresponding measures.
- Safeguarding and safety devices: Emphasises reduction of risks by design, guarding, interlocks and safety devices (trip bars, pressure-sensitive devices, interlocked movable guards) where appropriate.
- Machine elements: Guidance on drive and transmission enclosures, rollers, rotating shafts, conveyors, automatic equipment and other elements addressed via cross-reference to ISO 11111-1 Clauses 5 and 6.
- Verification and documentation: Contains clauses on verification of safety requirements and the need for instruction handbooks with safe threading-up, lap removal and special operation procedures.
- Practical examples: Recommends measures such as fixed guards for heavy-duty flyers, guarding of knotter/splicer and reeling faces, and placement of emergency stop pushbuttons (e.g., one on each end section).
Applications and who uses it
ISO 11111-4:2005 is used by:
- Textile machinery designers and manufacturers for compliant machine design and construction.
- Systems integrators and plant engineers when installing and integrating yarn processing and rope-making lines.
- Safety managers and compliance officers for risk assessment and guarding strategy.
- Machine operators and maintenance staff for understanding safe operation and required safeguards.
Typical applications include design, manufacture, installation and safe operation of twisting frames, texturing machines, reeling and winding systems, multi-head ball winders, stranders, lay-up machines and braiding equipment.
