Patent number: 9969137Abstract: Methods include providing a plurality fabric material layers, applying a plastisol layer between each fabric material layer forming plurality fabric material layers thereby creating a belt carcass, pressing the fabric material layers together with the plastisol layer(s) at a pressure of at least 5 psi to produce a preformed fabric carcass while heating the preformed fabric carcass while heating the preformed fabric carcass to a temperature which is within the range of about 360° F. to about 450° F. for a period of at least 6 minutes, disposing a thermoplastic elastomer polyvinyl chloride alloy composition onto the upper and lower surfaces of the fabric carcass, pressing the thermoplastic elastomer polyvinyl chloride alloy composition onto the upper and lower surfaces of the fabric carcass, and splicing opposing distal ends of the belt in a stepped splice configuration. The layers may be devoid of covering strips of lattice fabric disposed adjacent an abutment of any proximally positioned fabric layer.Type: GrantFiled: April 29, 2016Date of Patent: May 15, 2018Assignee: ContiTech Transportbandsysteme GmbHInventor: David Joseph Maguire

Patent number: 8007917Abstract: A non-halogenated rubber compound is provided for use in conveyor belts, particularly those used in underground mining. The non-halogenated rubber compound is fire-resistant in accordance with MSHA standards and produces acceptable levels of toxicity and smoke upon burning. Such non-halogenated rubber compound includes a blend of rubbery polymers in combination with aluminum trihydrate, which is a fire retardant, and optionally a phosphate plasticizer, which can provide the rubber compound with a more desirable workability. The blend of rubbery polymers is composed of natural rubber and butadiene rubber, and optionally styrene-butadiene rubber, such blend being present in a total amount of 100 phr. In one embodiment, the aluminum trihydrate is present in an amount of about 30 phr to about 150 phr. In another embodiment, the phosphate plasticizer is present in an amount of about 10 phr to about 60 phr.Type: GrantFiled: April 25, 2007Date of Patent: August 30, 2011Assignee: Veyance Technologies, Inc.Inventors: Kenneth Michael Alexander, David Joseph Maguire

Patent number: 7901016Abstract: The present invention is directed generally to track segments for track vehicles and, more specifically, to a track segment having an ethylene propylene diene monomer (EP(D)M) rubber based backer, and a method of making. In one embodiment, the track segment includes an EP(D)M rubber based backer including a rubber compound having 100 phr EP(D)M rubber wherein the diene component is optionally present, a peroxide curing agent, and one or more acrylic and/or methacrylic coagents. The track segment further includes a track pad and a track body. The track pad and backer cooperate with the track body to define the track segment for use in a track for a track vehicle. The EP(D)M rubber based compound provides a desirable balance of low heat build-up under heavy dynamic cyclic compression conditions, and also has a desirable load carrying capability, high heat resistance, and good cut/tear strength in hot climates.Type: GrantFiled: October 19, 2007Date of Patent: March 8, 2011Assignee: Veyance Technologies, Inc.Inventors: Thomas George Burrowes, Kathy Ann Folk, David Joseph Maguire

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
