ABSTRACT:
A device for removing a liquid, dusty or solid substance from a moving fabric or web. A roll is placed transversely in relation to the moving fabric or web and arranged to rotate around a rotation axis. The roll includes an outer mantle through which a liquid or air flow can enter the inside of the roll. The rotating roll is placed inside a chamber. The chamber includes an opening in a direction of the rotating axis. The opening is arranged to expose at least a part of the outer mantle such that the moving fabric or web tangential to the chamber can be supported against the outer mantle. At least a spiral, screw or threaded structure is arranged inside the rotating roll at a distance from the outer mantle, and is arranged to rotate around a rotating axis and to transfer liquid or air that has entered the roll in the direction of the rotation axis.
