## Abstract

A method of manufacturing a multi-axial laminate of webs produced from cables stretch broken into strips includes arranging, at an entry of a conveyor table, a first layer of pre-wound pre-cut strips along the longitudinal axis of the table, the strips being partially superimposed; arranging along the table at least two cross lappers transferring and depositing in an oblique and/or divergent position at predetermined angles a stretch broken strip; and arranging the strips in successive superimpositions on the first layer of pre-cut strips in different planes, to form a multi-axial web of stretch broken strips. The web then being treated by a fixing device. Movement of the support belt of the table taking place in steps to ensure the superimposition of the different layers of pre-broken strips deposited by the cross lappers. Implementation of the method taking place without any prior cohesion treatment of each strip.

## Claims

### Claim 1

A method of manufacturing a multi-axial laminate of webs produced from stretch broken cables in the form of strips, comprising: arranging, on a support belt of a conveyor table, at a feed thereto, by a transfer device, a first layer of pre-wound and pre-cut stretch broken strips along a longitudinal axis of the table, said strips being partially superimposed, arranging along the conveyor table at least two means of transferring the strips in an oblique and/or divergent position at predetermined angles each receiving a pre-broken strip and arranging them in successive superimpositions on the first layer of pre-cut strips in different planes, in order to form a multi-axial web of stretch broken strips, the web then being processed by a fixing device, movement of the support belt of the conveyor table taking place in steps in order to ensure superimposition of various layers of pre-broken strips by the transfer means, implementing of the method taking place without any operation of prior cohesion treatment of each of said strips, and wherein the transfer device and the at least two means of transferring each receive a pre-cut strip arranged directly without any other intermediate operation, the pre-cut strip comprising a carbon strip and a paper support strip, the transfer device and the at least two means of transferring being arranged to receive means of rewinding the paper strip after separation from the carbon strip.

### Claim 2 (depends on 1)

The method according to claim 1, wherein said means of transferring strips comprise cross lappers each receiving a pre-broken, pre-wound and pre-cut strip.

### Claim 3 (depends on 1)

The method according to claim 1, wherein said means of transferring strips comprise delivery carriages.
