Infrared motion sensor WeftMaster® FWL

Overview
The WeftMaster® FWL is a sensor for yarn, thread and tape processing machines. It continuously monitors weft insertion and yarn movement, detecting yarn loss, breakage or end-of-yarn events and sending an immediate stop signal to the machine.

Key features

• Accepts all yarn types: from fine yarns up to coarse tapes (e.g. synthetic rattan, carbon tapes).
• Flexible mounting: multiple orientations and mounting options for space-restricted or difficult machine conditions.
• Minimal thread tension: yarn or tape passes over a flat sensing surface with minimal additional tension.
• Wide monitoring scope: monitors weft insertion across the full fabric width and supports different weft yarns.
• Fast reaction: immediate machine stop signal on yarn outage detection.

Applications
Designed for yarn, thread and tape processing machines for inspection and continuous monitoring of weft insertion and thread movement.
