Abstract:
A method of manufacturing a blade assembly for a hydraulic power transmitting apparatus, said method comprising the steps of:feeding a belt-shaped metal plate in a longitudinal direction thereof; punching said metal plate to obtain a continuous semi-manufactured product having therein a plurality of blades and a pair of tie members to which a radially outer end and a radially inner end of each of said blades are connected, respectively; removing that one of said tie members which is connected to the inner end of each of said blades; twisting each of said blades to thereby erect each of said blades from a plane which includes the other of said tie members; bending each of joint pieces which are connected to the other of said tie members to thereby change a direction of said joint pieces; cutting the other of said tie members to thereby obtain a semi-manufactured product which contains therein a required number of blades; and fixedly joining the other of said tie members at both ends thereof into a ring shape.
