Abstract: A method for detecting the structure of a textile multi-filament product and a method for processing a textile multi-filament product includes detecting the structure. In the method for detecting the structure of the textile multi-filament product, a fed multi-filament product is optically detected in a linear/sectioned manner in a detecting direction different than the feeding direction in order to obtain primary detection data. The detection data are evaluated and a parameter and/or a change thereto describing the structure of the multi-filament product is derived therefrom. The parameter or the change thereto is used in the processing method to control a pre-processing step or a processing step.

Abstract: A three-dimensional (3D) textile structure with contours that are matched to the 3D textile structure is formed by folding a 2D textile structure. The three-dimensional textile structure has a areal weight of 100-5000 g/m2. A semi-finished three-dimensional fiber product is formed by infiltrating the 3D textile structure with thermosetting and/or thermoplastic resins and cured to form the three-dimensional semi-finished fiber product. The semi-finished product is then usable to produce leaf springs or profiles for the aerospace field, for the automobile field, for wind energy, and for sports articles.

Abstract: The invention relates to a method for producing a fibre layer with a longitudinal direction, wherein the method is based on the fact that fibre bundles having the same or a different fibre fineness which are guided in parallel are guided together in an overspread, overlapping manner and as a result are mechanically strengthened, wherein at least one sliver is obtained as a unidirectional layer with a defined width without additional fixing agent and/or additional mechanical or physical fixing methods.
