Self-Supporting 3-Legged Rotary Arm Stretch Wrapper

The WRTA-175 automatic rotary arm stretch wrapping system is a 3-legged self-supporting wrapper with no conveyor. Because pallet loads are wrapped on the floor, there is not weight limit. Great for pallet loads that are light and unstable or heavy.

Features of the WRTA-175

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

4-year unlimited cycle warranty
10-year warranty on steel structure
10-year warranty on 25" ring gear bearings
