• the process comprising the following consecutive steps:
• a) introducing, in a press, at least one layer for constituting a support, and at least one lining layer for the visible surface of the headliner;
• b) applying pressure and heat on the layers to obtain an assembly of layers joined to one another and having a predetermined shape;
• c) cutting the support such that at least one surplus portion of the support, not intended to be part of the stratified product, is separated from a main portion of the support, intended to be part of the stratified product, said at least one surplus portion of the support being joined to the main portion of the support by the lining layer after the cutting step;
• d) applying a hot fluid on the lining layer in an area corresponding to said at least one surplus portion of the support;
• e) separating said at least one surplus portion of the support from the lining layer, such that an assembly having the main portion of the support and the lining layer is maintained, a portion of the lining layer projecting with regard to the main portion of the support, in correspondence with at least one trimmed edge of the main portion of the support;
• and
• f) covering said at least one trimmed edge with the lining layer.
