Abstract

A draper belt ( 8 ) having a carry layer ( 14 ), a pulley cover layer ( 13 ), and a reinforcing layer ( 12 ) which is disposed between the carry layer ( 14 ) and the pulley cover layer ( 13 ). The draper belt ( 8 ) has a first edge ( 30 ) and a second edge ( 31 ), and cleats ( 7 ) on the carry layer ( 14 ) which run from the first edge ( 30 ) to the second edge ( 31 ) of the draper belt ( 8 ). The reinforcing rods ( 15, 18, 19, 20 ) contain metal. In some other aspects of the disclosure, two methods for ensuring adhesion between the reinforcing rods ( 15, 18, 19, 20 ) and the cleats ( 7 ) of the draper belt ( 8 ) are provided.

First claim

What is claimed is:

1. A draper belt comprising a carry layer, a pulley cover layer, and a reinforcing layer which is situated between the carry layer and the pulley cover layer, wherein the draper belt has a first edge and a second edge, wherein the carry layer includes a plurality of cleats which run from the first edge to the second edge of the draper belt, wherein the cleats are reinforced with reinforcing rods, and wherein the reinforcing rods are adhered to the cleats by:
extruding wire strips with an adhesive compound, wherein the wire is comprised of metal to be used in the reinforcing rods;
cutting the extruded wire strips and strips of fabric to specified lengths, wherein the fabric is comprised of the fabric to be used in the cleats;
laying the extruded wire strips onto the fabric strips; and,
curing the fabric strips and the wire, and simultaneously adding steel and rubber composite into a cavity centrally located within the cleats.

2. The draper belt as claimed in claim 1 , wherein the reinforcing rods are comprised of single strand, multi-end strips of wire.

3. The draper belt as claimed in claim 1 , wherein the reinforcing rods comprise woven wire, woven fabric cord, textile material, or monofilament.

4. The draper belt as claimed in claim 1 , wherein the reinforcing rods further comprise an ultra-high molecular weight polyethylene.
