With the pre-felt wrapped around the Gentle Roller drive roller you gain maximum efficiency of your felting process.
Firstly, there is no slippage of the felting roller, which can occur in some triangular roller systems where the felt roll can slip against the drive roller despite being pressure driven.
With the Gentle Roller, if the drive roller does one cycle, the fabric does one cycle as it is part of the drive system.

Secondly, while the Gentle Roller’s oscillating motion replicates hand rolling it is much more efficient than most felt makers can achieve, as it doesn’t tire as the day wears on, so you can be sure that each roll is the same length morning, noon and night.
