ABSTRACT:
Apparatus for longitudinally driving an elongate body (1) such as a rod or tube, comprises two opposed wheels (2) adapted to clamp the body (1) between them. The wheels (2) have an axis of rotation (3) lying substantially in a transverse plane of the elongate body (1). A drive (1) drives at least one of the wheels, wherein the wheels are adapted to transform the rotating movement of the wheels into a translating movement of the elongate body by means of friction. According to the invention the wheels (2) include a plurality of successive movably mounted intermediate pieces (12) circulating with the wheels and being supported by the wheels during the engagement with the body (1), the intermediate pieces (12) successively enabling the wheels (2) to engage the elongate body (1) a distance in longitudinal direction.
