A method for winding a skein-shaped windable product onto a spool formed of two spool halves (12, 14) which converge conically towards a middle radial plane (10) with two flange discs (16, 18) at the outer ends, includes the steps of rotating the spool about its central axis during the winding process, and feeding the windable product by a guide that moves along the length of the spool. There is further step of winding the windable product in layers substantially parallel to the lower conical surface up to the top conical surface, and the winding layers end respectively in a cylindrical surface connecting the circumference of the two flange discs (16, 18).
