Electro optical control to detect a filament passing through a guide eye and using a light emitting diode |
摘要 |
A guide eye is provided for a filament or strand material. An electro optical control mounted on a guide, to detect the presence of a filament or strand material, has its focus on the inner surface of the guide eye closest to the sensor. The filament or strand material moving within the guide eye, causes light to reflect from the sensor light source to the light sensor creating a signal indicating the presence of filament or the strand.
