In recent years, synthetic fiber ropes attracted much attention because it can increase the load capacity and reduce the size and the weight of the tendon drive mechanism. However, synthetic fiber ropes have a problem of large plastic elongation. That the amount of plastic deformation of the synthetic fiber ropes is very small in the range of loads smaller than the load applied in the past.“Pre-stretching”is performed to remove plastic elongation by applying a load in advance. However, the drawing equipment required for pre-stretching the ropes is very large and unsuitable for research purposes. Therefor, we have developed a stretching device that can pre-stretch even in narrow spaces. It was confirmed that the pre-stretching was done by actually pre-stretching with the developed drawing device and testing the prepared material.
