Fabric-web edge detection in a cutting machine

Detect the fabric roll start and position before cutting to prevent faulty cuts and missing control signals. An optoCONTROL CLS-K-31 fiber-optic sensor mounted on a cutting blade detects the fabric position and sends a PNP switching signal to the controller.

Application challenge

Detect the fabric roll start and position before cutting to prevent faulty cuts and missing control signals.

Measurement conditions

The sensor detects the fabric at approximately 140 mm; feed speed is 20 m/min. The source gives a material-dependent cutting-element positioning range of 0.5–2 mm.

Measurement method and system

An optoCONTROL CLS-K-31 fiber-optic sensor mounted on a cutting blade detects the fabric position and sends a PNP switching signal to the controller.

Documented performance

• Sensor-to-fabric distance in application: around 140 mm (cutting-machine application)
• Cutting-element positioning in application: 0.5 to 2 mm (cutting process; material dependent)
• Fabric feed speed: 20 m/min (cutting-machine application)

System components named by the manufacturer

• optoCONTROL CLS-K-31

Result

The source reports reduced waste and process disruption and robustness to scratches and contamination on the roller surface.
