The JAT series, which has been a world leader in energy saving performance, has evolved to further reduce air pressure and consumption. Toyota introduces the "i-SENSOR" weft insertion system. The world's first (*) weft sensing technology that detects weft insertion timing as the yarn is passing in REALTIME. The system then recommends proper adjustments of insertion timings to improve overall loom performance. (*)Based on Toyota research
JAT910 weft insertion system
Coordinated and inclusive weft insertion technology that enables stable operation at lower pressures reducing air consumption. Possible to reduce compressor air pressure as well.
Direct main air tank connection of valves/regulators greatly improves pressure responsiveness. As a result, weft yarn insertion becomes more efficient at lower pressures.
Direct connection of the air valves to the tandem and assist nozzles improve the stability and propulsion power of the yarn injection process.
Newly developed sub valve system with advanced flow path design achieves shorter injection time and increased weft insertion stability.
High efficiency regulator minimizes the loss of sub pressure from the compressor.
By obtaining a longer weft insertion time, further reductions of air pressure and consumption can be reached.
Toyota's original technology since the JAT810, the e-REED allows weft insertion at low pressure.
i-SENSOR detects weft yarn insertion timing as the yarn is passing inside the warp yarn. Each pick is analyzed and the system provides weft insertion setting recommendations for optimum weaving.
Unique algorithm designed by Toyota many years ago allows the visualization of the optimum sub air pressure and valve timings that provide the required weft insertion pressure.

Displays each sensor that controls weft insertion including the i-SENSOR that enables to stratify the type of mispick per nozzle.
Furthermore, provides guidance on adjustment points after input mispick conditions to improve production performance.
