Publication number: 20210197510Abstract: A method of forming a belt structure for a tire includes providing a drum having a center section. A first drum edge is near a first edge of the center section and a second drum edge is near a second edge of the center section. A first end surface extends from the center section first edge to the drum first edge and a second end surface extends from the center section second edge to the drum second edge, and a radius of each end surface is smaller than the center section radius. A rubber strip reinforced by a plurality of cords includes an outer edge and an inner edge. The strip is wound about the drum, turning from a first winding angle to a second winding angle on an end surface to reduce the tension and length differential between cords at the outer edge and inner edge of the strip.Type: ApplicationFiled: March 2, 2021Publication date: July 1, 2021Inventors: Peijun Liu, Matthew Jeremy List, Robert John Boehlefeld

Patent number: 7360571Abstract: A method of forming a composite belt structure for a tire is disclosed. The composite belt structure has cord reinforced layers including at least two radially outer zigzag belt layers. The cords per inch in the shoulder portion are greater than the cords per inch in the central portion as measured centered on the centerplane of the belt structure. The method discloses the steps of applying a multicord reinforced strip having a strip width SW onto a rotating crowned building drum, the strip being wound in a zigzag configuration to form at least two zigzag layers, wherein the crowned drum has non-overlapping portions of the strip placed in a central portion and extending in alternation to a pair of shoulder portions having portions of the strips overlapping to form belt layers.Type: GrantFiled: September 16, 2003Date of Patent: April 22, 2008Assignee: The Goodyear Tire & Rubber CompanyInventors: Kiyoshi Ueyoko, John Joseph Slivka, Roel Domingo Villanueva, Robert John Boehlefeld
