A piece of fabric, preferably foam-backed, is laminated to a concave, rigid substrate, such as a fiberglass shell for an automobile headliner, by: a) coating the back of the fabric with a heat activable adhesive, e.g., a powdered polyamide; b) placing the adhesive side of the fabric against the concave side of the substrate; c) preheating a perforated male die having a complementary shape to that of the substrate; d) pressing the die against the fabric; e) ejecting a shot of superheated vapor, preferably steam, through the fabric, thereby activating the adhesive; f) cooling the adhesive until it sets; and g) releasing the laminated article from the die. The treatment with the superheated vapor permanently stretches the fabric in the concavities, preventing delamination after the article is released from the die.
