Abstract: An arm of a forklift fork including a substantially horizontal arm having a supporting surface for supporting and carrying a load. The arm may include a carriage that also includes a supporting surface for supporting and carrying a load, wherein the carriage is arranged to move in parallel to the arm in relation to the supporting surface of the arm. The carriage may include a caterpillar track for moving. The arm may include two adjacent arm parts fastened to each other, between which parts the carriage is located. The arm may include several separate units, each containing members which make the load capable of rolling in parallel to the arm. Each unit is also arranged to remain in its place.

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.
