Publication number: 20240052531Abstract: A method for a fiber bundle, including a heating process of Joule-heating the fiber bundle by energization between at least a pair of electrodes. The fiber bundle is carried in contact with the electrodes and has electrical conductivity at least between the electrodes. At least one of the electrodes has an aggregating structure that aggregates the fiber bundle while being in contact with the outer surface of fiber bundle. The aggregating structure has a trench or cylindrical shape with a structural surface that narrows in the depth direction. When the electrodes are each composed of a rotating body, the aggregating structure is a trench provided on the outer surface of the rotating body. The trench has a bottom surface that narrows toward a rotation center side. The trench may have a widened portion on the outer peripheral edge side. The widened portion guides the fiber bundle to the bottom surface.Type: ApplicationFiled: July 27, 2023Publication date: February 15, 2024Applicants: KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHO, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yoshihide KATAGIRI, Takuya MORISHITA, Yuka YAMADA, Akira KUNITOMO
