Production of stranded wire

Abstract

Abstract PURPOSE: To produce a stranded wire continuously without chaning raw materials simply by chaning a part of constituting parts by cutting a blank materail which is being lef off continuously to plural strands by a rotary head disposed annularly with plural dies, feeding these out, and twisting these together. CONSTITUTION: A roughly drawn wire 4 to be supplied to the inside from between a stationary shoe member 18 and an external rotator 16 is entered while being given compression together with rotation of internal and external rotators 14, 16, and is delivered to the annular groove 17 side. Fresh compressive stress is given to the delivered wire 4 by the steep faces 25 of a rotary head 21 rotating in the direction opposite from that of the rotators 14, 16 and the wire is molded in a half-molten state as a strand 8 of a desired diameter by turning and cutting of dies 26 and is delivered out through a passage 27. These strands 8 are then maintained under constant tension by tension adhusting rolls 28 revolving simultaneously with the rotator 14. Thereafter, they are fed together with a central wire 2 supplied separately through a shaft hole 23 into a twisting mouth holder 9 through a twisting plate 29. One layer of concentrically stranded wires obtaind by twisting them together in the holder 9' is taken up by a take-up drum as a product. COPYRIGHT: (C)1982,JPO&Japio
