Stretch Wrap Machine Tension Adjustment
We recently wrote a blog post on stretch wrap machine film loading. The post was intended to help customers properly load a new stretch wrap machine with film. Understanding the proper film unwind and threading will prevent premature film tears and increase film efficiency.
As a follow-up post we want to provide details on adjusting tension settings after the film is threaded properly. Proper tension adjustment settings can reduce film waste, prevent damaged loads, and dramatically reduce film costs. For this post we are adjusting tension on a 2000B stretch wrap machine. See the easy step-by-step process below for adjusting your new machine from U.S. Packaging & Wrapping LLC.
Tie film to the pallet
After film threading is complete, tie the film to the pallet being wrapped.
Reset Turntable to “Home” Position and Press Start Button in Auto Mode
Once finished loading film into the machine, the E-stop will be on. Release the E-stop and hit the reset button. This will set the machine to the home position. When at the home position, press the start button to begin wrapping
Increase Turntable Speed Enough to Set Tension
Adjust turntable speed to between a 2 – 3. The turntable will move at a slow to moderate speed.
Adjust Tension Until the Dancing Roller Steadies
Slowly increase the tension dial. As tension increases, the dancing roller will reduce bouncing and steady.
Set Turntable Speed
Increasing the stretch wrapper turntable speed can also increase film tension. Once the dancing roller is steady, increase the turntable speed to reach the full film stretch rate before tearing.
Increase Film Carriage Speed
Once tension settings are properly adjusted, the film carriage speed can be adjusted. We recommend between a 2-3 to begin.
See the video below for film settings and how to watch for the dancing rollers to smooth out during set up.
