## Abstract

Apparatus for manufacturing a multi-axial laminate of webs produced from cables stretch broken into strips includes a conveyor table, a transfer device, at the entry thereof, arranging a first layer of pre-wound pre-cut strips along the longitudinal axis of the table, the strips being partially superimposed; at least two cross lappers arranged along the table 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 taking place without any prior cohesion treatment of each strip.

## Claims

### Claim 1

An apparatus for manufacturing a multi-axial laminate of webs from strips of stretch broken fibers comprising:
a conveyor table which moves in a longitudinal direction, the conveyor table having an upstream end, a downstream end and two longitudinal sides;
a plurality of multiple delivery carriages located at an upstream section of the conveyor table, wherein each multiple delivery carriage is configured to hold two reels of pre-broken and pre-wound carbon strips having a paper strip backing and to deposit the strips on the conveyor table to form a first layer of carbon strips;
a first single delivery carriage located downstream of the multiple delivery carriages, wherein the first single delivery carriage is configured to hold at least a single reel of pre-broken and pre-wound carbon strip having a paper strip backing and to deposit the strip on the first layer to form a second layer of carbon strips, and wherein the first single delivery carriage is arranged on one of the longitudinal sides of the conveyor table at a predetermined angle with respect to the longitudinal direction;
a second single delivery carriage located downstream of the first single delivery carriage, wherein the second single delivery carriage is configured to hold a single reel of pre-broken and pre-wound carbon strip having a paper strip backing and to deposit the strip on the second layer to form a third layer of carbon strips, and wherein the second single delivery carriage is arranged on one of the longitudinal sides of the conveyor table at a predetermined angle with respect to the longitudinal direction; and
a fixing device downstream of the second single delivery carriage which fixes the first, second and third layers together to form the multi-axial laminate.

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein at least one of the single and multiple delivery carriages further includes a device for rewinding the paper strip backing from a corresponding reel as the carbon strip is deposited.

### Claim 3 (depends on 2)

The apparatus according to claim 2, wherein the device comprises two driven spindles rotating in opposite directions, between which the paper strip backing passes, and a recovery cylinder, rotating in an opposite direction to the corresponding reel, and said driven spindles move the paper strip backing at a constant linear speed.

### Claim 4 (depends on 2)

The apparatus according to claim 2, further including rotation means for rotating the first single delivery carriage and the second single delivery carriage through 180°.

### Claim 5 (depends on 1)

The apparatus according to claim 1, wherein the multiple delivery carriages are arranged in parallel and slightly offset to distribute on the conveyor table as the table advances, the carbon strips in partial superimposition.
