ABSTRACT:
A cable for structures, especially suspension bridges, has a plurality of bundled tension elements spacedly surrounded by a tubular sheath, the space between tension elements and sheath being filled with a material, preferably injected mortar. To reduce the cost of producing, transporting and assembling such a cable, the tubular sheath is formed at the worksite from at least one sheet-steel strip in a shaping and seaming station and progressed along already tensioned tension elements, then sealed against anchorings for the cable, and filled with the mortar under pressure.
