    • A coil spring winding apparatus (1) comprises a stator and a rotor (10) which is supported on the stator so as to be rotatable about a rotation axis (13). The rotation axis (13) extends along a spring axis of a coil spring wound by the coil spring winding apparatus. At least one winding tool (21, 22) is supported on the rotor (10) so as to rotate about the rotation axis (13) of the rotor (10) upon rotation of the rotor (10). The at least one winding tool (21, 22) is configured to bend a wire (8) to form the coil spring upon rotation of the rotor (10). The at least one winding tool (21, 22) is adjustable relative to the rotor (10).
    • 螺旋弹簧卷绕装置(1)包括定子和转子(10),该转子(10)以可围绕旋转轴线(13)旋转的方式支撑在定子上。 旋转轴(13)沿着由螺旋弹簧卷绕装置卷绕的螺旋弹簧的弹簧轴线延伸。 至少一个卷绕工具(21,22)支撑在转子(10)上,以便在转子(10)旋转时绕着转子(10)的旋转轴线(13)旋转。 所述至少一个卷绕工具(21,22)构造成在所述转子(10)旋转时弯曲金属丝(8)以形成所述螺旋弹簧。 至少一个卷绕工具(21,22)相对于转子(10)可调节。
