ABSTRACT:
The invention relates to a method and an apparatus for the production of a helical spring from fiber-reinforced plastic, where a strand of fibers and plastic resin is wound onto a rotationally symmetric rotor provided with a spiral groove then hardened and finally removed from the rotor. In order to be able to produce helical springs with desired and in particular circular cross sections of the strand with small tolerances of the shape, a stator with an inner spiral groove is surroundingly disposed around the rotor, which spiral groove together with the spiral grooves of the rotor form the cross-sectional profile of the strand, where the rotor and the stator relative to the rotation of the rotor are shifted axially with respect to each other in an amount corresponding to the slope of the spiral grooves.
