Abstract:
1. A method for manufacturing a winding member provided with a plurality of links and a plurality of pins for connecting the links and wound around two pulleys of a continuously variable transmission, the method comprising: winding an endless shaped chain around a first pre-tension applying pulley of a pre-tension applying apparatus and a second pre-tension applying pulley of the pre-tension applying apparatus; applying a pre-tension to the chain; and removing the chain from the first and second pre-tension pulleys and subsequently winding the chain around the two pulleys of the continuously variable transmission, wherein each of sheave surfaces, which are mutually opposed to each other, of the first and second pre-tension applying pulleys has a concave curved portion, wherein an end face of each of the pins has a convex curved portion, wherein the concave curved portion of each of the sheave surfaces corresponds to the convex curved portion of the end face of each of the pins, and wherein a winding diameter of one of the first and second pre-tension applying pulleys of the pre-tension applying apparatus is less than a minimum winding diameter of the two pulleys of the continuously variable transmission.
