"textContent": "The method involves continuously bending a section of a spring band; cutting the bent section of the band into a spring rail; discontinuous reverse bending to reduce the internal stress of the bent cut-to length spring rail by subjecting the rail to at least one reverse bending force, and/or heat-treating the cut-to-length spring rails. The heat treatment is a low-temperature treatment at temperatures below 200 degrees C. The spring rails are coated and can have a painted or plastics coating.",
