红外线探边探头采用反射式红外光，不接触的感知布边，将布边位移线性的转换为-8V--0--+8V直流模拟信号，经控制器处理后由变频器驱动执行机构电机的转向和转速，齿条和机械驱动机构带动链轨跟随布边移动，保证针板或布夹扎住布边。少数黑色织物反射不足时，可旋转间接反射旋钮，使用间接反射杆工作。

Infrared edge detecting probe can detect fabric edge without contact because of the adoption of the reflection type infrared.It linearly transform the fabric edge into -8V--0--+8V DC analog signal ,the frequency converter drives the direction and revolution of actuator motor through the controller processing,the rack and mechanical actuator drive the caterpillar to move following the displacement of fabric edge,which guarantees the fabric edge is pinned by the faller bar or clip accurately. When few black fabric is lack of reflection,you can spin the indirect flection button to use the indirect flection rod.
