Motion detector WeftMaster® SW

weft breakpiezoelectricmonitoring

Overview
The WeftMaster® SW sensor detects yarn breaks and stoppages of the weft, reliably identifying moving or missing threads even at a minimum detectable thickness of 7 μm. It continuously monitors weft insertion across the full fabric width up to the selvedge.

Key features

• Instant detection of weft faults to prevent defective inserts from entering the fabric, reducing waste and improving production uptime.
• Effective detection regardless of yarn type, including threads down to 7 μm.
• Minimal additional tension on the yarn when passing the sensing head, based on long-term development and expertise.
• Monitoring up to the fabric selvedge across the entire width.
• Immediate machine stop upon missing weft to ensure product conformity while minimising false stops.
• Compatible with all yarn types.
• Engineered for efficient machine operation.

Versions

• WeftMaster SFW-L Mini — for projectile weaving machines.
• WeftMaster SW 10G — for rapier weaving machines.

Additional information

• Brochure available (English).
• Sensor designed to detect weft faults up to the fabric selvedge with minimal yarn tension.

Technical specifications
