Polymer impregnated fibers(4) are wound with a set orientation onto mandrels(16) of an auxiliary tool(8). The wound fibers are then stripped from the mandrels as they are placed into an open two-part molding tool(21) and the tool is closed to apply pressure and consolidate the molding. Fibers(4) are wound spool-like onto the mandrels as the auxiliary tool is moved by a handling system(14). Some or all of the winding mandrels move relative to each other depending on the required fiber orientation. Wound fibers are heated by hot gas, in particular hot air, or electrical radiation, especially infra-red. Fiber are guided over a heated transfer roll (9) during winding. The transfer roll may be swiveled around an axis extending in the fiber direction. Independent claims are included for: a) the process equipment which includes an auxiliary tool(8) with winding mandrels(16) having a stripping mechanism for removing the wound fibers; b) the claimed auxiliary tool; c) a polymer component reinforced with continuous fibers, for use in the automobile industry, and based on at least one thermoplastic elastomer(TPE).
