Abstract
A machine for laminating fabric (123) to open cell cushion foam (124) while forming design lines in the foam is disclosed. The machine comprises a top hollow die (21) having perforations (38) and a complementary, hollow bottom die (54) which also has perforations (130). Hot melt adhesive (125) is interleaved between fabric (123) and foam (124). Top die (21) is preheated to just below the melt point of adhesive (125); then dies (21) and (54) are closed against the layered workpiece, with top die (21) contacting the face of fabric (123). A shot of superheated steam, e.g., at 80 psig and 700.degree. F., is ejected from perforations (38) and (130) to melt adhesive (125). Then a vacuum is applied to the perforations to pull ambient air through the workpiece and cool it. The resolidified ashesive (125) holds foam (124) in its deformed shape and laminates fabric (123) to the foam.
