Abstract
A draper belt (8) having a carry layer (14), a pulley cover layer (13), and a reinforcing layer (12) which is situated between the carry layer (14) and the pulley cover layer (13). The carry layer (14) includes a plurality of cleats (7) which are reinforced with reinforcing rods (15). The draper belt (8) has a first edge section (16), a second edge section (17), and a center section (18) located between the first edge section (16) and the second edge section (17). The first edge section (16) and the second edge section (17) of the draper belt (8) each have a modulus that is at least three times greater than the modulus of the center section (18).
Claims18
A draper belt comprising:
- a carry layer on a first side of the draper belt, wherein the carry layer includes a plurality of cleats, wherein the cleats are reinforced with reinforcing rods;
- a pulley cover layer on a second side of the draper belt;
- a reinforcing layer which is situated between the carry layer and the pulley cover layer, and
- an edge section of the belt;
- a center section of the belt, and
- wherein the pulley cover layer is narrower in the edge section than in the center section;
- an edge fabric reinforcement of the edge section has a higher belt modulus than a center fabric reinforcement of the center section;
- and
- the edge fabric reinforcement is configured to enhance adhesion between rubber in the belt and the edge fabric reinforcement by having been treated in a resorcinol formaldehyde latex (RFL) dip.
A draper belt comprising:
- a carry layer, wherein the carry layer includes a plurality of cleats, wherein the cleats are reinforced with reinforcing rods;
- a reinforcing layer which is situated between the carry layer and the pulley cover layer, and
- an edge section of the belt;
- a center section of the belt,
- wherein the edge section has an edge belt modulus greater than a center belt modulus of the center section and the carry layer is narrower in the edge section than in the center section;
- and
- an edge fabric reinforcement within the edge section is configured to enhance adhesion between rubber in the belt and the edge fabric reinforcement.
A draper belt comprising:
- a carry layer that includes a plurality of cleats reinforced with reinforcing rods, a pully cover layer and a reinforcing layer situated between the carry layer and the pulley cover layer;
- a center section of the draper belt having a center belt modulus based on a center fabric reinforcement;
- and
- an edge section of the draper belt having an edge belt modulus based on an edge fabric reinforcement and wherein the edge belt modulus is greater than the center belt modulus and wherein the edge fabric reinforcement is at least partially located in the pulley cover layer and the pulley cover layer is narrower in the edge section than in the center section;
- and
- the edge fabric reinforcement is configured to enhance adhesion between rubber in the belt and the edge fabric reinforcement by having been treated in a resorcinol formaldehyde latex (RFL) dip.
