Abstract: A method for determining mechanical properties of a first rolled material by a hybrid model that includes production datasets relating to further rolled materials, a physical production model and a statistical data model. The production dataset relating to the first rolled material is used to determine a first mechanical dataset, a further production dataset and a metallurgical dataset and also a second mechanical dataset. An averaged normalized distance value for production datasets relating to the further rolled materials is determined that is used to ascertain the mechanical properties of the rolled material as a weighted average from the first and second mechanical datasets. When creating the hybrid model, the physical production model is used to determine further production datasets relating to the further rolled goods for training the statistical data model.

Abstract: The invention relates to a method for continuously roller-forming and hardening sheet steel in which a sheet steel strip is continuously roller-formed into a profile in a roller-profiling unit, characterized in that the roller-formed profile strand is preheated to a temperature below the austenite starting temperature (Ac1) and the roller-formed profile strand is then heated across subregions of its cross-section and/or subregions of its length to a temperature above AC3, with the roller-formed profile strand being acted on with tension at least during the heating of subregions to a temperature >AC3.

Abstract: A profile is produced from a bent metal sheet surrounding an interior space by at least 360°, the longitudinal edges of said metal sheet being connected to respectively adjacent wall sections of the metal sheet. The longitudinal edges are separated from the respectively adjacent wall sections or longitudinal edges by spacers and are connected thereto in a form-fitting manner by fasteners such as screws, rivets, or the like.

Abstract: A device for wine or fruit growing, having at least one metallic trellis post and having at least one, in particular metallic, profile piece, which is fastened to the trellis post and has at least one holding element for a tensioning wire. In order to facilitate handling of the device and to increase its stability, the invention proposes providing a closed rectilinear guide between the trellis post and the profile piece, of which guide the trellis post forms, on the longitudinal side, a rail-like guide element on which the profile piece is guided in sliding fashion, and providing an open snap connection of which the profile piece has a spring element that engages with the trellis post M detent fashion.

Abstract: The invention discloses a method for producing a structural component, in particular for a vehicle, in which a piece of sheet metal is shaped into an open or closed, in particular multi-chambered, hollow profile and is provided with at least one electrical cable, which the piece of sheet metal holds at least in some areas. In order to achieve advantageous method conditions. the invention proposes that the piece of sheet metal be provided with the cable during its shaping or between two of its shaping steps and be attached to this cable in at least some areas in a nonpositive or integral fashion.
