## Abstract

Manufacturing process for vehicle headliners comprising a substrate and at least one decorative lining extending along one of the faces of said substrate, joined to each other through a layer of adhesive, which specifically comprises the union of the decorative lining to the previously shaped substrate using a thermosetting adhesive with a high viscosity.

## Claims

### Claim 1

Process for manufacturing vehicle headliners comprising the following stages:
a) arranging a previously shaped three-dimensional substrate and a decorative lining;
b) applying a layer of thermosetting adhesive with a Brookfield viscosity between 1000 and 2500 mPa·s measured at 25° C. with a no. 3 spindle and rotational speed of 20 rpm on the decorative lining;
c) introducing the shaped three-dimensional substrate in a thermoforming mould at a temperature between 110 and 150° C.; wherein a predetermined shape of the thermoforming mould corresponds to the previously shaped three-dimensional substrate;
d) introducing the decorative lining together with the layer of thermosetting adhesive on the shaped three-dimensional substrate such that the layer of thermosetting adhesive is in front of the shaped three-dimensional substrate;
e) closing the thermoforming mould and applying pressure to establish the union between the decorative lining and the shaped three-dimensional substrate through the layer of thermosetting adhesive;
f) opening the thermoforming mould and extracting the headliner.

### Claim 2 (depends on 1)

Process for manufacturing vehicle headliners according to claim 1, wherein the adhesive application stage b) is performed using adhesive application rollers.

### Claim 3 (depends on 1)

Process for manufacturing vehicle headliners according to claim 1, wherein the layer of thermosetting adhesive after setting on the headliner obtained in stage f) has a grammage of 10 to 35 g/m2.

### Claim 4 (depends on 1)

Process for manufacturing vehicle headliners according to claim 1, wherein said stage d) further comprises stretching the decorative lining so that the lining remains taut.
