Abstract
Rotating winch for stranding lines comprising a hollow rotor (1) wherein a motor (9) suitable for rotating a drawing drum (12) around an axis perpendicular to the axis of rotation of the rotor (1) is arranged, the external lateral surface (21) of said drawing drum (12) having a substantially concave profile which is included between two containment walls (22, 22′). Said profile is preferably symmetrical and has a substantially constant radius of curvature, equal to about the double of the distance between the containment walls (22, 22′) and to about ⅔ of the external diameter at the center of the drawing drum.
