<p>A method for tensioning springs made from spring band steel, preferably leaf springs, whereby intermediate layers (5, 6) are arranged between metal tensioning elements (2, 3) and the tensioning region of the spring (1) in order to reduce the additional loading of the spring (1) caused by the tensioning. The material used for the intermediate layers (5, 6), preferably teflon, has a higher sliding capability than the material of the tensioning elements (2, 3) and the tensioning surfaces of the tensioning elements (2, 3) are provided with a roughness such as can be obtained, for example, by subsequent blasting with a granular or sharp-edged blasting material. As a result, the formation on the spring (1) of rust caused by friction and the lateral escape of the intermediate layers (5, 6), preferably produced in the form of foil, especially on the forward tensioning edge, is prevented.</p> |
