Description Overview This machine can roll pack three sizes: 25 mm, 52 mm, and 76 mm. Toppers must be folded up to achieve the same exit diameter of 47 cm (18 ½ inches). Operation Fold the 76 mm topper up 2 times. Fold the 52 mm topper up 3 times. Fold the 25 mm topper up 5 times or more. Toppers are folded up to make their thickness the same, so they come out with the same exit diameter of 47 cm (18 ½ inches).
