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