Method for producing bent spring rails from an endless spring band
Abstract:
The invention relates to a method for producing bent spring rails from an endless spring band. The method is characterized by the following steps: continuous bending of a section of spring band; cutting the bent section of spring band into a spring rail; discontinuous reverse bending to reduce the internal stresses of the bent, cut-to-length spring rail by subjecting the spring rail to at least one reverse bending force and/or heat-treating the cut-to-length spring rails, the heat treatment being a low-temperature treatment in this case, preferably at a temperature of less than 200 *C.
