Patent number: 11801547Abstract: A conveyer equipped with rotating discs rotatable around axes thereof relative to a mounting base. Each of the rotating discs has grooves in which rectangular wires are receivable. When an upstream and a downstream one of the rotating disc are arranged in a given angular relation to each other, one of the grooves of the upstream rotating disc is aligned with that of the downstream rotating disc to pass the rectangular wire from the upstream rotating disc to the downstream rotating disc. Upon such passing of the rectangular wire, the grooves of the upstream and downstream rotating discs hold or clamp all side surfaces of the rectangular wire, thereby ensuring the stability in retaining the rectangular wire when passed from one to another of the rotating discs, which enables the conveyer to carry the rectangular wires at high speeds.Type: GrantFiled: December 10, 2020Date of Patent: October 31, 2023Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHA, AISIN AW CO., LTD.Inventors: Takeshi Kurosawa, Kazuhiko Fukuda, Hiroaki Takeda, Ryosuke Maruyama, Toshiro Nakamura, Tadashi Fujiyoshi, Daisuke Mizushima, Hideki Mukaizaka
