A winding assembly for elastic thread (F) has a bobbin spindle (A) with numerous freely rotating tubes (T) and a motor-driven cylinder (R) which turns bobbins (B) on the tubes by friction. The bobbin spindle (A) especially has a fixed geometric axis (X) and a slide (Z) which can be lifted periodically, independent of the motor-powered cylinder and bobbin support spindle. The motor-powered cylinder (R) is positioned over and upstream of the bobbin spindle (A), feeding the thread (F) to the bobbin (B) around the cylinder (R) curved surface. The winding assembly has a slide (Z) with numerous moving guides (G) which make alternate straight movements parallel to the bobbin axis, distributing the threads (F) on the bobbins. Periodically the slide (Z) moves away from the bobbin, increasing the distance from the guide (G) and winding surface. The motor-powered cylinder (R) moves vertically and is located above the bobbin spindle (A). The drive cylinder (R) rises slowly with respect to the spindle (A) as the bobbin (B) diameter increases, maintaining permanent contact with the surface. The motor powered cylinder (R) is fixed to a vertical guide (E).
