Abstract

[Problems] To provide power transmission chain manufacturing method and apparatus which can prevent a pin against damage when, by increasing a pre-tension, a more proper residual compression stress is applied to a link. [Means for Solving Problems] The manufacturing apparatus comprises a pre-tension applying apparatuswhich includes a first pre-tension applying pulleyand a second pre-tension applying pulleyaround which an endless shaped chaincan be wound. The mutually opposed sheave surfacesandof the pre-tension applying pulleysandare respectively formed to have a concave shape which corresponds to the convex curved portionof the end face of a pin
