  • Method of manufacturing a seat
    Patent number: 7090739
    Abstract: Hot-melt webs are located on an outer surface of a pad member and an inner surface of a cover member, individually. The pad member and the cover member are heated to melt the hot-melt webs by means of heaters from the sides opposite the webs, individually. As fibrous hot-melt adhesive elements are cut at every turn and separated to insular pieces, they are distributed like mist drops in the outer surface of the pad member and the inner surface of the cover member. Thereafter, the pad member and the cover member are superposed and pressurized so that they are bonded to each other.
