    Patent number: 5254197
    Abstract: An apparatus (10, 10', 10'') for adhesively bonding a fabric layer (16) to a cellular foam pad (18) using a heat-sensitive adhesive (14) to produce a seat cushion assembly (12). The apparatus (10, 10', 10'') includes a microwave radiation source (22, 22', 22'') for emitting microwaves to selectively heat the adhesive (14) above its melting temperature to adhesively bond the fabric layer (16) to the foam pad (18). A method is also provided for fabricating a cushion assembly (12) in accordance with the subject invention.
