Why is the film tearing or slipping at the cutter, dispenser, or gripper during wrapping?

Summary:

This article outlines potential causes and solutions for film tearing or slipping issues during the wrapping process.

Issue:
The film is tearing on the cutter’s sliding sections, at the dispenser, or slipping out of the gripper.

Possible Causes and Solutions:

1. Film Quality:
   • Poor quality film may be prone to tearing.
   • Reduce film stretch from 70% to 55% on the dispensers to lower tension.

   • Note: Lowering the stretch will increase film usage.

      

2. Cutter Burrs or Sharp Edges:
   • Inspect the sliding section of the film cutter for burrs or sharp corners.

   • Apply grease if necessary to reduce friction.

      

3. Wrap Arm Positioning:
   • If the wrap arm goes too far past the cutter, it may pull the film too tightly.

   • Check the DELAY TO STOP setting on the controller.

      

4. Cutter Timing:
   • Ensure the cutter opens fully before the wrap arm passes.

   • A partially open cutter may not capture the film properly.

      

5. Gripper Wear:
   • Worn gripper rubbers can allow the film to slip.

   • Inspect and replace if necessary.

      

Next Steps:

• Review the machine settings and physical components listed above.

• Contact support if the issue persists after troubleshooting.
