Manufacturing process of sheet-like bodies comprising seat parts for vehicles and the like
First Claim
1. A manufacturing process of sheet-like bodies to be used as seat parts for vehicles, said process comprising the subsequent steps of:
- fastening an adhesive acrylic resin layer (2) on a surface of a base layer (1), said base layer comprising a woven or unwoven piece of textile fibers, thereby obtaining a first object;
die-pressing said first object, thereby obtaining a second object;
pre-molding and corresponding hot forming of the second object, thereby obtaining a third object;
introducing the third object in a mold, placing a first surface of the third object in contact with the walls of the mold, wherein said first surface is a visible surface of the base layer (1);
depositing on said mold a thermostable material mass (5) formed of polyester-fiber glass, in contact with a second surface of said third object, said second surface being essentially complementary to said first surface; and
hot pressing the contents of the mold, thereby obtaining a single molded sheet-like body.

Abstract
It consists of continuous production of a woven or unwoven piece of textile fibers, to whose piece a layer that is going to be the middle one is affixed on the back surface. It is thick enough to offer resistance to the passing of a thermostable material that will be finally affixed to the same, wherein it will remain imbedded. The textile compound formed of the two layers referred to first of all, the second layer being an unwover layer, is subjected to a hot pre-forming process. Then it is inserted in a mold in which the thermostable material formed by a polyester-fiber glass mass is placed, hot pressing the whole and obtaining a rigid and resistance sheet-like body, whose visible surface is covered with the layer of textile compound that is highly resistant to vandalism. If the textile piece is consistent or thick enough, the middle layer could be eliminated, in which case the polyester-fiber glass mass would remainly closely affixed to that textile piece, with the insertion of the respective waterproof adhesive layer.
