Patent number: 10759093Abstract: According to a production method of a power transmission belt, a shaped structure having a cylindrical shape is placed radially inward of belt mold having a cylindrical shape. The shaped structure is provided on a mandrel and has a plurality of ridges arranged adjacent to one another in an axial direction of the shaped structure. The belt mold has a plurality of compression layer-shape grooves arranged adjacent to one another in an axial direction of the belt mold. The shaped structure is crosslinked by heating and pressing the shaped structure toward the mandrel while each of compression layer-forming portions, which are comprised of the plurality of ridges of the shaped structure, is fitted in an associated one of the compression layer-shape grooves of the belt mold, thereby molding a cylindrical belt slab.Type: GrantFiled: September 29, 2018Date of Patent: September 1, 2020Assignee: BANDO CHEMICAL INDUSTRIES, LTD.Inventors: Masaki Miyanishi, Naohisa Harushige, Yohei Hattori, Takashi Matsuoka, Yusaku Taoshita, Hisashi Izumi

Patent number: 10538042Abstract: A production method of a raw edge V-belt uses a belt mold having a plurality of compressed rubber layer-shape grooves arranged adjacent to one another. A shaped structure having a plurality of compressed rubber layer-forming portions on an outer peripheral surface is crosslinked to form a belt slab, while the compressed rubber layer-forming portions fitted in the respective compressed rubber layer-shape grooves of the belt mold. The belt slab is cut into ring-shaped pieces such that one ring-shaped piece corresponds to one compressed rubber layer-forming portion.Type: GrantFiled: September 21, 2018Date of Patent: January 21, 2020Assignee: BANDO CHEMICAL INDUSTRIES, LTD.Inventors: Naohisa Harushige, Tomoaki Hata, Yusaku Taoshita, Hideaki Kawahara, Masaki Miyanishi, Yohei Hattori, Hirokazu Sakurai

Patent number: 10532528Abstract: A shaped structure and a fabric material are set in a belt mold such that the shaped structure and the fabric material are respectively positioned inside and outside with respect to each other. While each of compression layer-forming portions comprised of ridges of the shaped structure covered with the fabric material is fitted in an associated one of compression layer-shaping grooves of the belt mold, the shaped structure is pressed toward the belt mold and heated to be crosslinked, and integrated with the fabric material, thereby molding a cylindrical belt slab. The belt slab is cut into ring-shaped pieces having two or more of the compression layer-forming portions.Type: GrantFiled: September 28, 2018Date of Patent: January 14, 2020Assignee: BANDO CHEMICAL INDUSTRIES, LTD.Inventors: Naohisa Harushige, Kouichi Tsujino, Tomoaki Hata, Hideaki Kawahara, Hisashi Izumi, Yohei Hattori, Koichi Hosokawa

Patent number: 10343358Abstract: A surface sheet which is to constitute a surface layer and a core sheet which is to constitute a core layer are prepared. A plurality of ridges is formed on the core sheet, and the surface sheet is bonded such that the surface sheet covers the plurality of ridges, thereby forming compression layer-forming portions.Type: GrantFiled: August 30, 2018Date of Patent: July 9, 2019Assignee: BANDO CHEMICAL INDUSTRIES, LTD.Inventors: Naohisa Harushige, Yohei Hattori, Koichi Hosokawa, Hisashi Izumi, Tomoaki Hata
