Method and apparatus for winding lengths of flexible material, packages produced by such method and apparatus, as well as endforms forming part of the mandrels on which such windings are formed, incorporate a number of winding parameters which are related to one another by a mathematical formula. Specifically, the mathematical relationship <IMAGE> where: A=the guide stroke, Gd=the guide distance from the spindle center line axis, G=the gain or advance of the wind, Dm=the diameter of the wind or coil, and Ym=the wind or coil width; governs the shape of the walls of the endform and such end-forms are used in winding apparatus for producing wound packages of flexible material. From the above equation, the geometrical shape of the wound package can also be determined.
