Abstract
In a method for controlled winding of an elongated object, at least one elongated object (11) is guided by a guide head (35) to a reel body (15, 16), which is mounted to rotate and is rotated by a drive member (20). A program controlled adjustment of the speed variation as well as for the torque of the driver member (20) occurs, and depends on the measurable winding diameter (15') for a winding operation of the reel body (15, 16). By means of a regulator (50), the actual value of a tensile force on the elongated object (11) is measured by the torque on the drive member (20), and is compared with an adjustable reference value. In the case of a divergence, an actual value (57) is returned to the reference value. The reel body (15, 16) in this case rests on at least two driven drive shafts (22, 24). In addition, a lifting device for receiving the reel body is provided.
