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).
Claims19
A detention unit for retrieval of an elongated body, comprising:
- first and second sets of movable friction surfaces, said first set including at least first and second movable friction surfaces, each said movable friction surface of said first set being provided with and operatively coupled to a respective, separate propulsion unit, said second set including at least one movable friction surface, each said movable friction surface of said second set being provided with and operatively coupled to a respective, separate propulsion unit;
- each movable friction surface including an arc section for receiving and pulling the elongated body;
- and
- said sets of movable friction surfaces being disposed in mutually opposed relation and said elongated body extending sequentially therebetween whereby said elongated body extends sequentially from the arc section of said first movable friction surface of said first set to the arc section of a first movable friction surface of said second set and then to the arc section of said second movable friction surface of said first set.
A detection unit for retrieval of an elongated body comprising:
- first and second sets of movable friction surfaces, each said set of movable friction surfaces including at least one movable friction surface, each said movable friction surface of each said set being provided with and operatively coupled to a respective, separate propulsion unit;
- each movable friction surface including an arc section for receiving and pulling the elongated body;
- and
- said sets of movable friction surfaces being disposed in mutually opposed relation and said elongated body extending sequentially therebetween whereby said elongated body extends sequentially from the arc section of a first movable friction surface of said first set to the arc section of a first movable friction surface of said second set;
- wherein a plane of said first movable friction surface of said first set that includes said arc section thereof is inclined at an angle of greater than zero degrees with respect to a plane of said first movable friction surface of said second set that includes the arc section thereof,
- wherein said first set comprises at least two movable friction surfaces.
