The position of the front top roller is adjustable. Therefore, it is possible to optimize the offset of this roller corresponding to draft, setting and fibre length. The pressure is transmitted to the top rollers directly by the unique Rotorcraft weighting elements. Absolutely no internal friction can occur. The pressure between top and bottom rollers remains constant, improving fibre control.

All top rollers are loaded by individual weighting elements without losing the advantage of central loading and unloading by air pressure. The pressure between top and bottom rollers remains constant, irrespective of any change in the setting of the top rollers, improving fibre control.
