Safety-critical woven webbings—such as automotive seat belts, fall-arrest and fall-protection systems, rescue and recovery straps, and other components of personal fall protection equipment (PFPE)—are subject to the highest requirements regarding strength, durability, and functional reliability.
Even minor deviations in mechanical properties can compromise the performance and safety of the final product.
Consistent process monitoring and complete traceability
For this reason, reproducible product characteristics, stable and controlled manufacturing processes, and complete traceability of materials and production parameters are essential.
Only through consistent process monitoring and quality assurance can the required standards be met on a long-term basis while ensuring a consistently high level of product safety.
A key prerequisite is the precise and uniform feeding of warp yarns throughout the weaving process.
Since the warp yarns carry the majority of the tensile loads during service, maintaining constant warp yarn tension is fundamental to achieving uniform load distribution, reproducible strength values, and consistently high fabric quality.
Documented Warp Yarn Tension for Maximum Process Reliability
In the production of safety-critical webbings, precise tension control alone is often not sufficient. Increasingly, manufacturers are required to document and verify production conditions in order to comply with quality standards, audit requirements, and traceability regulations.
CREALET warp let-off systems enable the continuous measurement and recording of warp yarn tension throughout the entire production process.
Tension deviations, limit violations, and resulting machine stops can be automatically documented and analyzed.
In addition, the complete tension profile can be recorded over the entire warp beam length or production run. This provides transparent documentation of the tension conditions under which the fabric was produced, creating a valuable basis for quality assurance, process optimization, and batch traceability.
Particularly for seat belts, fall-arrest systems, rescue straps, and other load-bearing webbings, comprehensive recording of warp tension data provides an additional level of transparency, quality assurance, and process security.
The recorded process data offer numerous benefits:
- Early detection of process deviations
- Documentation of warp tension faults and machine stoppages
- Verification of stable production conditions
- Support for quality management and audit processes
- Improved batch traceability
- Basis for reproducible product properties
- Increased process reliability for safety-critical applications
