An apparatus and a method for producing an elongated profiled part, in which a profiled strip is produced from a flat strip by rolling and the profiled strip is embossed in sections, by means of which at least one longitudinal section of the profiled strip is offset relative to at least one other longitudinal section in a direction perpendicular to the longitudinal direction of the profiled strip, and with which method the strip is trimmed in such a way that, after the embossing, the longitudinal sections that are offset relative to each other have different cross-sections. In order to increase the reproducibility of the method, before the profiling, the flat strip is trimmed in such a way that by means of the embossing of the trimmed and profiled strip, the longitudinal sections that are offset relative to each other have different cross-sections.

Apparatus and method for producing an elongated profiled part

A method for manufacturing a semifinished product or component is disclosed in which a metal support embodied as a split strip is covered with at least one prepreg containing a thermally cross-linkable thermosetting matrix with endless fibers, the thermosetting matrix of the prepreg is pre-cross-linked by means of heating, and the metal support covered with the pre-cross-linked prepreg is formed into a semifinished product or component by means of roll forming. In order to enable plastic deformation in fiber-reinforced regions of the metal support, it is proposed that during the pre-cross-linking of the thermosetting matrix of the prepreg, its matrix is transferred into a viscosity state that is higher than its minimum viscosity and prior to reaching its gel point, the prepreg is formed together with the metal support.

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 (Ac) 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 AC, with the roller-formed profile strand being acted on with tension at least during the heating of subregions to a temperature &#x3e;AC.

Method for producing roller-formed, partially hardened profiles

A method for manufacturing a semifinished product or part is disclosed in which a metal support embodied as a metal sheet or blank is covered with at least one prepreg containing a thermally cross-linkable thermosetting matrix with endless fibers, the thermosetting matrix of the prepreg is pre-cross-linked by means of heating, and the metal support covered with the pre-cross-linked prepreg is formed into a semifinished product or part by means of deep drawing or stretch deep drawing. In order to enable plastic deformation in fiber-reinforced regions of the metal support, it is proposed that during the pre-cross-linking of the thermosetting matrix of the prepreg, its matrix is transferred into a viscosity state that is higher than its minimum viscosity and prior to reaching its gel point, the prepreg is formed together with the metal support.
