ABSTRACT:
The invention discloses a method and an apparatus for winding a cord continuously. A rotation of a winding bobbin around which a cord to be a tension member of a belt, is wound and detected directly or indirectly. A cord is forwarded in an axial direction of a winding bobbin at a pitch, which corresponds to a diameter of the cord, in relation to a rotation of a winding bobbin. The bobbin axis of the winding bobbin is rotated at a constant speed by rotation driving means so that the cord is wound around the winding bobbin. The rotation of the bobbin axis is detected by rotation detection means directly or indirectly. The cord is forwarded in the axial direction of the winding bobbin in relation to the rotation of the winding bobbin at a pitch which corresponds to the diameter of the cord by receiving signals from the rotation detection means.
