摘要

PROBLEM TO BE SOLVED: To provide a method for acquiring a roller drawing plate spring from a roller drawing plate spring material collection sheet to mount it to a clutch body, and the roller drawing plate spring material collection sheet used for the method carried out at a low manufacturing cost and high yield by quickening assembly speed to shorten assembly time to thereby improve productivity. SOLUTION: A large number of roller drawing plate spring materials 11 are connected at a fixed part so as to be in comb tooth shape and supplied as a roller drawing plate spring material collecting sheet, and individual roller drawing plate spring materials 11 are formed one by one by cutting from the roller drawing plate spring material collection sheet 10 to form roller drawing plate springs. The supply of the clutch body provided with a nest part of the roller drawing plate spring is carried out by synchronizing a process of supplying the roller drawing plate spring material collection sheet, with a process of cutting and forming the roller drawing plate spring material from the collection sheet, in a roller drawing plate spring insertion position, and inserting the roller drawing plate spring in the nest part 6 of the clutch body 1.
