In order to gain desired pinning success at the inlet of stenter machines or any pin chain tenter frames IR edge control sensor is used as a state of art technology.
The EF-ECU model sensor permits infrared scanning of the fabric edges in accordance of the reflection principle the fabric is used as a reflector. The correct distance to the fabric, 35 mm is always ensured by EFFE mechanical spreading unit adjustment. Chain rails activation speed can be adjusted by PLC according to the desired level.
