Abstract

The chain is made from round or D-section steel strip in the form of oval links. The links (1, 2) have flattened zones in the region of their long arms, which are linked by arcs. These zones are created by local plastic deformation to alter the initial cross section of the links in these zones. The long arms of every other link may have a flattened zone perpendicular to a plane through the centers of both of them.
