Abstract

An endless belt is provided includes a compression section, a tension section, and a cover layer, together defining a longitudinal direction of the endless belt. The tension section has a plurality of tensile members extending at an angle of 0° to 45° relative to the longitudinal direction of the endless belt, and the tensile members are orientated a zig-zag pattern. In some cases, the plurality of tensile members extend along the longitudinal direction of the belt at an angle of 0°. Each of the plurality of tensile members may be continuous or discontinuous. The tensile members may be laid in a plane substantially parallel with the longitudinal direction of the belt. The tension section may include two sets of a plurality of tensile members, where the first set tensile members are orientated in a first zig-zag pattern and the second set of tensile members are orientated in a second zig-zag pattern.

First claim

What is claimed is:

1. An endless belt comprising a compression section, a tension section, and a cover layer, which define a longitudinal direction, wherein the tension section comprises a two sets of tensile members extending at an angle of 0° to 45° relative to the longitudinal direction of the endless belt, and wherein the tensile members are orientated a zig-zag pattern; and,
wherein a first set of tensile members are orientated in a first zig-zag pattern and a second set of tensile members are orientated in a second zig-zag pattern, and wherein the first zig-zag pattern and the second zig-zag pattern have different pattern frequencies.

2. The endless belt of claim 1 wherein the plurality of tensile members are extended along the longitudinal direction of the endless belt at an angle of 0°.

3. The endless belt of claim 2 wherein each of the plurality of tensile members is continuous.

4. The endless belt of claim 1 wherein the tensile members are laid in a plane parallel with the longitudinal direction of the belt.

5. The endless belt of claim 1 wherein the first set tensile members provide a first modulus and the second set of tensile members provide a second modulus.

6. An endless belt comprising a compression section and a tension section, wherein the tension section comprises two sets of a plurality of tensile members extending at an angle of 0° to 45° relative to the longitudinal direction of the endless belt, and wherein the tensile members are orientated a zig-zag pattern; and,
wherein a plurality of tensile members of a first set are orientated in a first zig-zag pattern and a plurality of tensile members of a second set are orientated in a second zig-zag pattern, and wherein the first zig-zag pattern and the second zig-zag pattern have different pattern frequencies.

7. The endless belt of claim 6 wherein each of the plurality of tensile members extends in a longitudinal direction along the endless belt.

8. The endless belt of claim 7 wherein each of the plurality of tensile members is continuous.

9. The endless belt of claim 6 wherein the two sets of a plurality of tensile members are laid in separate planes which run parallel with the longitudinal direction of the endless belt.

10. The endless belt of claim 6 wherein the two sets of a plurality of tensile members are in contact and are laid in a plane which runs parallel with the longitudinal direction of the endless belt.

11. The endless belt of claim 6 wherein the first set tensile members provide a first modulus and the second set of tensile members provide a second modulus.

12. The endless belt of claim 6 wherein the plurality of tensile members extending at an angle of 0° to 30° relative to the longitudinal direction of the endless belt.

13. The endless belt of claim 6 having an elongation in the range of from 0.5% to 10%.

14. An endless belt comprising a compression section, a tension section, and a cover layer, which define longitudinal direction, wherein the tension section comprises two planar sets of a plurality of tensile members extending along the longitudinal direction of the endless belt, wherein each of the plurality of tensile members is continuous, and wherein each of the tensile members is orientated a zig-zag pattern; and,
wherein a first planar set of tensile members are orientated in a first zig-zag pattern and a second planar set of tensile members are orientated in a second zig-zag pattern, and wherein the first zig-zag pattern and the second zig-zag pattern have different pattern frequencies.
