ABSTRACT:
The present invention provides a method of manufacturing a seat comprising a skin material, a cushioning pad and a seat frame by bonding the skin material and the cushioning pad to each other by using a reactive hot melt adhesive, wherein the method comprises a step of coating an adhesive to the cushioning pad, a step of assembling the seat frame to an attaching die in which a movable press bonding plate is disposed, a step of attaching a cushioning pad to the seat frame assembled to the attaching die, provisionally assembling the skin material to the surface of the cushioning pad on the side of coating the adhesive and then moving the press bonding plate thereby arranging the seat frame, the cushioning pad and the skin material on an attaching die main body, a step of applying heating by a heating die from the side of the skin material attached in the assembling step and a cooling/press bonding step of applying cooling under pressure after the heating step by a cooling die from the surface of the skin material to the attaching die.
