ABSTRACT:
Fabric is glued to a foam cushion, while design lines are formed in the cushion, by pressing a hot, perforated die against a layered composition of foam, hot melt adhesive, and fabric. Protruding ridges in the die are heated to a higher temperature than the land area. Superheated steam is ejected through the perforations, causing the foam to melt and form the design lines, and causing the layer of adhesive to become molten. The composition is then cooled, for example by pulling air through it, to resolidify the adhesive and the molten foam under the ridges. The process is useful for forming automobile seats. It requires less labor than forming the design lines by sewing, and without damaging the fabric.
