Cut and Wipe System

Pneumatically operated cut and wipe-on system automatically cuts and wipes the film onto the load upon cycle end
First a vertical roller positions the film over the clamp which grabs the film, ensuring longer heat wire life expectancy
Then the heat wire swings in and cuts the film
A timed impulse heat control allows quick cool down so the heat wire becomes cold to the touch within 5 seconds
