BELT-TYPE TRACTION MEANS AND METHOD FOR FABRICATING THE TRACTION MEANS AS WELL AS USE OF SAID TRACTION MEANS IN AN ELEVATOR AND AN ELEVATOR PROVIDED WITH SAID TRACTION MEANS

摘要

The object of the invention is a belt-type traction means, which comprises a herringbone toothed belt, which has at least a tooth part and a support structure supporting the tooth part, which support structure comprises a plurality of reinforcement means in the longitudinal direction of the toothed belt. In the transverse direction of the toothed belt the toothed belt comprises two edge parts side by side and a center part between the edge parts connecting the edge parts, the spring constant of which center part in the transverse direction of the toothed belt is smaller than the corresponding spring constant of the edge parts. In addition, the object of the invention is a method for fabricating the aforementioned traction means and the use of the traction means in an elevator as well as an elevator provided with the aforementioned traction means.
