Abstract
The invention relates to a method for producing a bandlike-elongated, spring-elastic element (12) for supporting a rubber-elastic wiper strip (22) of a windshield wiper for vehicles, which element has two spring rails (26, 28), located with a spacing (24) from one another and essentially parallel to one another, which at least on both of their end portions are solidly joined together by transverse ribs (30) that are disposed on the one band face (14) of the spring rails and that span the spacing (24). An especially advantageous production method for such a support element is obtained in that the prefabricated spring rails (26, 28) are solidly joined together in pairs and oriented essentially parallel to one another by means of at least one bandlike retaining element (44) oriented transversely to the spring rails; that the gridlike combination (54) thus obtained is subjected to at least one further method step, by which, by cutting the retaining element (44) between the applicable pairs of spring rails (26, 28), the support elements (12) are released from the combination (54).
