ABSTRACT A composite, heavy-duty spool with plastic end cones, consisting of a cylindrical spool body of thick, rigid, heavy cardboard having open ends, and a pair of plastic end cones. When dismantled, the end cones can nest in each other so as to occupy little space. Each end cone comprises a truncated, conical body portion all parts of which are essentially of uniform thickness. At its small base part, each body portion has a transverse wall that is apertured to receive a draft bolt, and has a plurality of integral strengthening ribs each of which is disposed both on the conical exterior and on the transverse wall exterior. The ribs lie in planes which pass through the axis of the body portion, and are shaped to effect a lead-in formation at the aperture of the transverse wall, to guide a draft bolt to the aperture. The advantage of the present construction over the devices of the prior art are that the spool is rust- resistant, light-weight and yet sturdy, and the individual parts readily lend themselves to quick assembly so as to keep the manufacturing and storage costs low.
