Wire ropes in which adjacent layers of wires within a strand are in line contact are also known as parallel-lay wire ropes. The strands are formed by twisting wires of various specifications; the pitch of the wires in each layer is the same, but the lay angle varies. Depending on the arrangement of the wires within the strand, line-contact wire ropes are classified into four types: Walentin, Sill, filled, and Walentin-Sill. In line-contact wire ropes, not only do the wires within the same layer make line contact, but adjacent wires also make line contact; furthermore, the wires in each layer of the strand have the same lay direction (see Wire Rope Laying Methods) and pitch.
