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.

Abstract translation: 本发明涉及一种从环形弹簧带生产弯曲弹簧导轨的方法。 该方法的特征在于以下步骤：一段弹簧带的连续弯曲; 将弹簧带的弯曲部分切割成弹簧导轨; 不连续的反向弯曲，以通过使弹簧导轨受到至少一个反向弯曲力和/或热处理切割到长度的弹簧导轨来减小弯曲的切割长度的弹簧导轨的内部应力，热处理为 在这种情况下，优选在小于200℃的温度下进行低温处理。

Abstract: A wiper blade for a wiper system for wiping motor vehicle windows includes a wiper blade rubber squeegee, which has a wiping lip that faces the window, a rear part that faces away from the window, and a tilting connecting element that joins the wiping lip to the rear part. The wiper blade also includes a strip-like elastic supporting element, or at least one spring rail, which stabilizes the wiper blade rubber squeegee. The supporting element can be joined to a wiper arm which can be transversally driven with regard to the longitudinal extension of the wiper blade and which can be tensioned against the window. The wiper blade is additionally provided with a casing or covering which surrounds, at least in sections, the rear part and the supporting element or the at least one spring rail. The casing is provided with a streamlined form, surrounds the rear part, and when viewed in a direction parallel to the window and of the longitudinal extension of the wiper blade, covers the tilting connecting element. Alternately, the covering is held on the at least one spring rail.
