Is the process by which the leaf is twisted and the leaf cell walls ruptured to bring the juices to the surface of the leaf. The rolling machines have deep jacket, a pressure cap to apply pressure on the leaf, and the table itself has battens and a cone at the center to twist the leaf. There are also the more modern "Rotorvane" machines, which also give the same twisting and turning effect. This process takes about 20 to 30 minutes.

Thereafter to separate the twisted leaf from the untwisted, and to reduce the heat build up, the rolled leaf is passed over a roll breaker. This machine has meshes which separate rolled leaf. The unrolled is put back into the rollers for further rolling whilst the rolled leaf is fermented.
