Abstract
A method for producing a windshield wiper bracket (10) with a U-shaped cross section, with two through holes (12) disposed in the legs (11) of the bracket (10), through which a rivet (13) extends, wherein the method includes the following steps: production of through holes (12) in a flat bracket blank (14); insertion of a rivet slug (15) into one of the through holes (12); folding of the legs (11) to produce the U-shaped profile and to thereby position the rivet slug (15) in a position aligned with the other through hole (12); sliding of the rivet slug (15) into the position extending through both of the through holes (12), and riveting of the rivet slug (15).

A method for producing a windshield wiper bracket with a U-shaped cross section, with two through holes disposed in legs of the bracket, through which a rivet extends, wherein the method includes the following steps:
- production of through holes (12) in a flat bracket blank (14);
- insertion of a rivet slug (15) into one of the through holes (12);
- folding of the legs (11) to produce a U-shaped profile and to thereby position the rivet slug (15) in a position aligned with the other through hole (12);
- sliding of the rivet slug (15) into a position extending through both the through holes (12), and
- riveting of the rivet slug (15).
An apparatus for producing a windshield wiper bracket with a U-shaped cross section, wherein the apparatus has folding means for producing a U-shaped profile out of a flat bracket blank, which is provided with two through holes, a positioning mechanism for sliding a rivet blank into the through holes, which are aligned with each other after the production of the U-shaped profile, and deformation means for producing at least one rivet head on a rivet slug, characterized in that the folding means (22, 23), the positioning mechanism (16), and the deformation means (18) are disposed in a single processing station.
