Abstract
A detention unit is provided for retrieval of an elongated body (9), such as a cable. The unit includes two or more movable friction surfaces (1, 11) adapted to pull in the elongated body (9). The moveable friction surfaces (1, 11) are arranged relative to each other so that the elongated body (9) may bear or rest against at a part of at least two friction surfaces (1, 11) in a sequential manner. The part of the friction surfaces (1, 11) adapted to pull the elongated body (9) defines a arc section, and each friction surface is provided with a separate propulsion unit (3, 14).
