Apparat og fremgangsmåde til fremstilling af et fiberkompositprodukt

摘要

The invention relates to a device for producing a toroid-shaped fiber composite product. The device comprises at least two fiber or fiber composite material dispensing units (2, 3), the dispensing units being adapted to place a fiber (4) or a fiber composite material onto the surface of a toroid-shaped mandrel (5); positioning means to effectuate relative movement of the mandrel and the dispensing units during placement of the fiber or fiber composite material. The invention further relates to a method for producing a toroid-shaped fiber composite product, preferably with a concave cross-section, in particular the rim of a bicycle wheel. The method comprises providing a toroid-shaped mandrel, dispensing fibers or fiber composite material from at least two dispensing units, placing the fibers or fiber composite material onto the mandrel while effectuating a relative movement of the mandrel and the dispensing units, and reshaping at least part of the mandrel, preferably by thermoforming.
