A sheet metal profile support ( 10 ) for automotive construction, such as a cross member, rocker panel, or frame support is disclosed, with a U-shaped, parabolic, or horseshoe-shaped profile cross section ( 12 ), in which, in at least one section ( 14 ) of the two legs ( 16, 18 ) of the profile, a first and second sheet metal layer ( 20, 22 ) rest flush against each other as a sheet doubling and in the region of the free ends of the legs ( 16, 18 ), the sheet metal layers ( 20, 22 ) are connected to each other in one piece by means of a beaded edge ( 32 ) that has a hollow chamber ( 34 ). In order to improve the torsional rigidity and damping and to extend the service life, the hollow chamber ( 34 ) of the beaded edge ( 32 ) in the region of the free ends of the legs ( 16, 18 ) is preferably completely filled with glue ( 24 ) and the glue ( 24 ) is introduced between the sheet metal layers ( 20, 22 ), at least in the section ( 14 ) of the flush-contacting sheet doubling in the region of the legs of the profile, and the sheet metal layers ( 20, 22 ) are bonded to each other by means of the glue ( 24 ), in particular by means of a glue layer ( 26 ). In addition, a method for producing a sheet metal profile support of this kind is disclosed, which is distinguished by the fact that during the shaping, glue ( 24 ) is introduced between the first and second sheet metal layers ( 20, 22 ) at a time when the sheet metal layers ( 20, 22 ), in the section ( 14 ) that will form the flush sheet doubling later in the shaping process, are disposed approximately in a V-shape ( 48 ) in relation to each other (FIG. 2 ).

1. A sheet metal profile support ( 10 ) for automotive construction with an essentially U-shaped, parabolic, or horseshoe-shaped profile cross section ( 12 ), in which, in at least one section ( 14 ) of the two legs ( 16 , 18 ) the profile, a first and second sheet metal layer ( 20 , 22 ) rest essentially flush against each other as a sheet doubling and in the region of the free ends of the legs ( 16 , 18 ), the sheet metal layers ( 20 , 22 ) are connected to each other in one piece by means of a beaded edge ( 32 ) that has a hollow chamber ( 34 ), characterized in that the hollow amber ( 34 ) of the beaded edge ( 32 ) in the region of the free ends of the legs ( 16 , 18 ) is filled with glue ( 24 ) and that the glue ( 24 ) is introduced between the sheet metal layers ( 20 , 22 ), at least in the section ( 14 ) of the flush-contacting sheet doubling in the region of the legs of the profile, and the sheet metal layers ( 20 , 22 ) are bonded to each other by the glue ( 24 ). 2. The sheet metal profile support according to claim 1, characterized in that a curved or arc-shaped connecting section ( 28 ) of the two legs ( 16 , 18 ) is constituted by the first and second sheet metal layers ( 20 , 22 ), which form a hollow chamber ( 30 ). 3. The sheet metal profile support according to claim 2, characterized in that the hollow chamber ( 30 ) has an essentially sickle-shaped cross sectional profile. 4. The sheet metal profile support according to claim 1, characterized in that the hollow chamber ( 34 ) has an essentially teardrop-shaped cross sectional profile. 5. The sheet metal profile support according to claim 1, characterized in that the sheet metal profile support ( 10 ) is formed out of a one-piece sheet ( 36 ) or sheet metal band and the longitudinal edges ( 38 , 40 ) of the sheet are bonded to each other along a butt seam ( 42 ) extending in the direction of the longitudinal axis of the sheet metal profile support ( 10 ). 6. The sheet metal profile support according to claim 5, characterized in that the butt seam is disposed in a central section of a sheet metal layer ( 20 , 22 ) of the connecting section ( 28 ) of the two legs ( 16 , 18 ). 7.

The sheet metal profile support according to claim 1, characterized in that the glue ( 24 ) is disposed at least in sections of the hollow chamber ( 30 ) of the connecting section ( 28 ) in the region of the ends of the sickle-shaped cross sectional profile pointing toward the legs ( 16 , 18 ). 9. A method for producing a sheet metal profile support ( 10 ) in which a central region ( 44 ) of an essentially flat sheet ( 36 ) or sheet metal band is shaped into a first sheet metal layer ( 20 ) with an essentially U-shaped, parabolic, or horseshoe-shaped profile cross section ( 12 ), and then the edge regions ( 46 ) of the sheet ( 36 ) are shaped into a second sheet metal layer ( 22 ) with an essentially U-shaped parabolic, or horseshoe-shaped profile cross section ( 12 ), and after the shaping is completed, the second sheet metal layer ( 22 ) encompasses or embraces the first sheet metal layer ( 20 ), characterized in that during the shaping, glue ( 24 ) is introduced between the first and second sheet metal layers ( 20 , 22 ) at a time when these sheet metal layers ( 20 , 22 ), in the section ( 14 ) that will form the flush sheet doubling later in the shaping process, are disposed approximately in a V-shape ( 48 ) in relation to each other. 10.
