| 摘要 |
The present invention relates to a method wherein a first end and a second end of a pre-tensioned spring are positioned against a first and second stop. A rotating body is first rotated about its longitudinal axis such that the first end engages once in a cam wheel during each rotation, the wheel having at least X+1 teeth and at least one cam that runs parallel with the teeth. The cam wheel thus rotates one tooth further with each rotation of the rotating body. The rotating body is subsequently subjected to pre-tensioning until the cam wheel and its cam lies against a third stop and the first end engages the cam wheel. The rotation is then continued in order to increase the torque.
