The belt has a first edge section, a second edge section, and a load carrying section. The first edge section and the second edge section are located on each side of the conveyor belt, and the load carrying section is located between the first second edge sections. The reinforcement layer is comprised of a woven fabric which has weft threads extending across the width of the belt and passing into both the first edge section and the second edge section of the conveyor belt. The woven fabric also has warp threads located in the load carrying section of the conveyor belt extending longitudinally throughout the belt without passing into either the first or the second edge section. ## Claims ### Claim 1 A conveyor belt comprising a pulley cover layer, a carry cover layer, and at least one reinforcement layer disposed within the belt between the pulley cover layer and the carry cover layer, wherein the belt comprises a first edge section, a second edge section, and a load carrying section, wherein the first edge section and the second edge section are located on opposing sides of the conveyor belt and the load carrying section is located between the first edge section and the second edge section, wherein the reinforcement layer is comprised of a woven fabric comprising weft threads extending across the width of the belt and passing into both the first edge section and the second edge section, wherein the woven fabric has warp threads located in the load carrying section of the conveyor belt extending longitudinally throughout the belt without passing into either the first edge section or the second edge section of the conveyor belt, wherein the woven fabric consists of weft threads in the first edge section and the second edge section and warp threads and weft threads in the load carrying section, and wherein the first edge section and the second edge section of the conveyor belt do not extend across more than 30% of the total width of the conveyor belt. ### Claim 2 (depends on 1) The conveyor belt according to claim 1, wherein the first edge section and the second edge section of the conveyor belt do not extend across more than 20% of the total width of the conveyor belt. ### Claim 3 (depends on 2) The conveyor belt according to claim 2, wherein the first edge section and the second edge section of the conveyor belt do not extend across more than 10% of the total width of the conveyor belt. ### Claim 4 (depends on 1) The conveyor belt according to claim 1, wherein the conveyor belt is a baler belt. ### Claim 5 (depends on 1) The conveyor belt according to claim 1, wherein the belt is about 520 inches (13,208 mm) long. ### Claim 6 (depends on 1) The conveyor belt according to claim 1, wherein the belt is about 23 (584.2 mm) inches wide. ### Claim 7 (depends on 1) The conveyor belt according to claim 1, wherein the first edge section and the second edge section are devoid of warp threads. ### Claim 8 (depends on 1) The conveyor belt according to claim 1, wherein the first edge section and the second edge section each have a width of no more than 10 inches (254 mm). ### Claim 9 (depends on 8) The conveyor belt according to claim 8, wherein the first edge section and the second edge section each have a width of no more than 5 inches (127 mm). ### Claim 10 (depends on 9) The conveyor belt according to claim 9, wherein the first edge section and the second edge section each have a width of no more than 1 inch (25.4 mm). ### Claim 11 (depends on 1) The conveyor belt according to claim 1, wherein the woven fabric is formed of a nylon material. ### Claim 12 (depends on 1) The conveyor belt according to claim 1, wherein the woven fabric is formed of a polyester material. ### Claim 13 (depends on 1) The conveyor belt according to claim 1, wherein the woven fabric is formed of a polyester material and a nylon material. ### Claim 14 (depends on 1) The conveyor belt according to claim 1, wherein the woven fabric is formed of a polyester material. ### Claim 15 (depends on 1) The conveyor belt according to claim 1, wherein the pulley cover layer and the carry cover layer each comprise one or more materials selected from the group consisting of natural rubber, synthetic polyisoprene rubber, cis-1,4-polybutadiene rubber, nitrile rubber, ethylene-propylene-diene rubber (EPDM), styrene-butadiene rubber (SBR), styrene-isoprene rubber (SIR), and styrene-isoprene-butadiene rubber (SIBR). ### Claim 16 A conveyor belt comprising a pulley cover layer, a carry cover layer, and at least one reinforcement layer disposed within the belt between the pulley cover layer and the carry cover layer, wherein the belt comprises a first edge section, a second edge section, and a load carrying section, wherein the first edge section and the second edge section are located on opposing sides of the conveyor belt and the load carrying section is located between the first edge section and the second edge section, wherein the reinforcement layer is comprised of a woven fabric comprising weft threads extending across the width of the belt and passing into both the first edge section and the second edge section, wherein the woven fabric has warp threads located in the load carrying section of the conveyor belt extending longitudinally throughout the belt without passing into either the first edge section or the second edge section of the conveyor belt, wherein the first edge section and the second edge section are devoid of warp threads, and wherein the woven fabric consists of weft threads in the first edge section and the second edge section and warp threads and weft threads in the load carrying section. ### Claim 17 (depends on 16) The conveyor belt according to claim 16, wherein the first edge section and the second edge section of the conveyor belt do not extend across more than 30% of the total width of the conveyor belt. ### Claim 18 (depends on 16) The conveyor belt according to claim 16, wherein the belt is about 520 inches (13,208 mm) long. ### Claim 19 (depends on 16) The conveyor belt according to claim 16, wherein the belt is about 23 (584.2 mm) inches wide. ### Claim 20 (depends on 16) The conveyor belt according to claim 16, wherein the first edge section and the second edge section each have a width of no more than 10 inches (254 mm).
