Abstract: A palm-top fabric leading edge detector adapted to be incorporated in a high temperature or regular temperature, L-configured or U-configured dyeing machine includes a detector body which is releasably connected to a sensor mounted in the dyeing machine via a cable to receive a fabric leading edge detection signal from the sensor when the leading edge of a fabric that is moved through the dyeing machine for dyeing passes through the sensor. The detector processes the fabric leading edge detection signal and provides the detection result on a display on the detector body. The detector is driven by an internal power source which may be primary cells or secondary cells rechargeable by means of external power source. Visual indicator and audio signal generation device are provided to indicate the detection of the fabric leading edge in a visual and audio manner.
