Abstract
According to the invention a winding head (1,40) is realized with expanding sectors (15,41) for the rotation of a tubular center (23,44) around which a tape (26) is wound. The sectors (15,41) are radially forced against the internal surface (22,43) of the tubular center (23,44) by means of the radial movement of splines (9) and of rolling elements (17) placed on horizontal surfaces (11) of the splines (9). Said rotation is caused by the rotation of the sectors (15,41) to which said rolling element belong, caused by the tension (27) of the tape (26) being wound around the tubular center (23,44).
