Abstract (en)
[origin: WO2014094732A1] The invention relates to a method for producing a spring made of fiber composite material, in which a laminate strand which is formed from fibers of fiber composite material and is impregnated with a matrix material that can be consolidated is reshaped into a spring geometry. The invention also relates to a device for carrying out the method. On the method side, it is proposed that, prior to reshaping the laminate strand (2), a strand-shaped preproduct (20) is formed by applying a deformable protective jacket (16), which encloses the laminate strand (2), in a continuous application process. On the device side, it is proposed that an application unit (15) for forming a protective jacket (16) around the laminate strand (2) is arranged downstream of the processing device (1) in the transport direction of the laminate strand (2).
