Abstract
The method includes using a contoured mold (22) with copper tubing (40) coiled and embedded beneath the contoured surface. The fabric or trim cover (14) and an adhesive film (16) is placed on the mold (22) and drawn by a vacuum in to contour with the mold (22). The foam cushion (12) is placed thereon in compression. The adhesive film (16) includes a polyamide resin doped with micron sized ferromagnetic particles. Copper coil tubing (40) is energized by an oscillatory radio frequency generator (50) to produce a magnetic flux to induce eddy currents in the ferromagnetic particles to generate heat to thereby melt the polyamide resin. The adhesive film melts, creating a bond between the trim cover (14) and the foam cushion (12).
