Patent number: 6518207Abstract: An improved agricultural belting (1) formed of multiple fabric by layers (2, 3 or 4), interposing rubber layers (5, 6) and rubber cover layers (7, 8). The fabric plies are a woven of warp yarns (10) extending in the longitudinal direction of the belt (1) and fill yarns (11) extending in the transverse direction of the belt (1). To optimize the transverse stiffness of the belting and other properties of the belt, any of the fabric plies (2, 3, or 4) are formed with selective replacement of the multifilament fill yarns (11) with monofilament cords (13). The fabric ply (2, 3, or 4) formed with monofilament cords (13) has at most fifty percent monofilament fill cords (13).Type: GrantFiled: January 15, 2001Date of Patent: February 11, 2003Assignee: The Goodyear Tire & Rubber CompanyInventors: Frederic Pember Andresen, Jenny Zhaoxia Yu

Patent number: 6427728Abstract: A belting (10) reinforced with at least one fabric ply (16). The fabric ply (16) is a composite fabric (26). The fabric (26) has two woven layers (28, 30) and an intermediate third layer of straight warp yarns (34). The woven layers (28, 30) and straight warp yarns (34) are bound together by a plurality of binder yarns (38). Each layer (28, 30, 34) of the fabric (26) contributes substantially 25-40% to the overall strength of the fabric (26). The composite fabric (26) may be used in a multi-ply belting (10) for heavy duty applications; wherein the fabric ply (26) is the center ply (16) and provides approximately 50 to 75% of the overall belting strength. The fabric (26) may also be used as a single reinforcing ply for light duty application belting.Type: GrantFiled: December 14, 1999Date of Patent: August 6, 2002Assignee: The Goodyear Tire & Rubber CompanyInventors: David Joseph Maguire, Jenny Zhaoxia Yu, Frederic Pember Andresen
