## Abstract

A basic fabric for an adhered fabric of a transmission belt, provided with an upper face and a lower face and having warp yarns in a longitudinal direction and weft yarns in a transverse direction is provided. The warp yarns have a predefined degree of elasticity and the weft yarns have a lower elasticity than the warp yarns. The weave of the basic fabric is Inverted Batavia weave.

## Claims

### Claim 1

A basic fabric for an adhered fabric of a high-performance belt, having an upper face and a lower face, and comprising warp yarns in a longitudinal direction and weft yarns in a transverse direction, orthogonal to the longitudinal direction, wherein the warp yarns have a predefined elasticity and the weft yarns have less elasticity than the warp yarns, wherein a weave of the basic fabric is such that the warp yarns and the weft yarns form a pattern on the upper face identical to a pattern on the lower face, and wherein the weave is Inverted Batavia weave.

### Claim 2 (depends on 1)

The basic fabric of claim 1, wherein the Inverted Batavia weave has a weave ratio of from 6:4 to 180:4.

### Claim 3 (depends on 1)

The basic fabric of claim 1, wherein, considering a 25 mm wide specimen, a percentage elongation in a warp direction is between 15 and 50 times the percentage elongation in a weft direction, when the 25 mm wide specimen is subjected to a force of 100 N.

### Claim 4 (depends on 1)

The basic fabric of claim 1, wherein each warp yarn comprises one or more parallel yarns.

### Claim 5 (depends on 1)

The basic fabric of claim 1, wherein each warp yarn comprises one or more twisted yarns.

### Claim 6 (depends on 1)

The basic fabric of claim 1, wherein each warp yarn comprises one or more textured yarns.

### Claim 7 (depends on 1)

The basic fabric of claim 1, wherein each warp yarn comprises one or more taslanized yarns.

### Claim 8 (depends on 1)

The basic fabric of claim 1, wherein each warp yarn comprises a yarn core having an elastic yarn, and a yarn complement having in turn one or more yarns, either parallel, twisted, textured, or taslanized, and wherein the yarn complement wraps said yarn core along its extension.

### Claim 9 (depends on 1)

An adhered fabric for a high-performance belt, comprising
a basic fabric according to claim 1,
wherein the basic fabric is incorporated in a matrix of polymeric materials.

### Claim 10 (depends on 9)

A high-performance belt comprising an adhered fabric according to claim 9.

### Claim 11

A process for manufacturing a basic fabric for an adhered fabric of a high-performance belt, the process comprising:
providing warp yarns having a predefined degree of elasticity and providing weft yarns having a lower elasticity than the warp yarns;
producing by weaving the basic fabric comprising the warp yarns in a longitudinal direction and the weft yarns in a transverse direction, orthogonal to the longitudinal direction, with a weave of the basic fabric such that the warp yarns and the and weft yarns form a pattern on an upper face of the basic fabric identical to a pattern on a lower face of the basic fabric, wherein said weave is Inverted Batavia weave.

### Claim 12 (depends on 11)

The process of claim 11, wherein the Inverted Batavia weave has a weave ratio of from 6:4 to 180:4.

### Claim 13 (depends on 11)

The process of claim 11, wherein, considering a 25 mm wide specimen, a percentage elongation in a warp direction is between 15 and 50 times the percentage elongation in a weft direction, when the 25 mm wide specimen is subjected to a force of 100 N.
