Dual towers combine the stability and load containment of an X-pattern with the speed of a one-way wrap. While one of the carriages wrap from bottom up, the other carriage wraps from top to bottom; reducing the number of rotations while achieving the same load containment as a conventional dual-way wrap.
Use one tower to wrap the bottom load while the second tower wraps the top load separately. Obtain two individually wrapped loads simultaneously - cutting yor time in half.
Same a lot of time by applying the same amount of stretch film with fewer revolutions by using the two film carriages to wrap a single load.
Two towers provide options. Increase efficiency by equipping one of the carriages with pneumatic roping or banding to increase load containment with a minimum number of rotations. Or use one of the otwers to secure the top and bottom portion of the load during the first rotation to improve load stability.
