Cause Analysis:
Sheet deviation (also known as lateral misalignment) during the roll forming process is typically caused by the following factors:

The center roller is not in the correct position.

The feeding guide board is not perfectly perpendicular to the forming axis, causing the material to veer off its intended path.

Solutions:
To effectively eliminate deviation issues, the following corrective actions should be taken:

Reposition the Center Roller:
Realign and recalibrate the center roller to ensure it is perfectly centered. Accurate positioning of this roller is critical to maintaining material alignment throughout the forming process. This is especially important in Cold Roll Forming Machines used in high-precision applications like tile cutting slitting machines or step-by-step metal cutting machines.

Adjust the Feeding Guide Plate:
Carefully examine the angle between the feeding guide and the forming shaft. If it's not perpendicular, realign it accordingly. Observing the direction of sheet deviation can help identify which side needs adjustment. In advanced setups such as the steel coil slitting line metal steel coil simple slitting and cutting machines, guide accuracy directly affects output precision.

Enhanced Observation and Calibration:
Monitor the material flow during production. If misalignment persists, further fine-tune both the center roller and the guide board in small increments until optimal alignment is achieved. This step is vital for systems equipped with bearing-supported slitting mechanisms and motor-powered metal slitting machines, where precise tracking and cutting are required.

Automation and Repeatability:
For high-speed and fully automated systems like the full automatic C/Z interchangeable purlin machines, maintaining perpendicular feed and consistent centering is essential to avoid material waste and ensure long-term reliability. These adjustments also apply to cold roll forming machine systems handling various profiles and thicknesses.
