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.

Abstract translation: 热熔网分别位于衬垫构件的外表面和盖构件的内表面上。 加热衬垫构件和盖构件，以分别从与腹板相对的侧面通过加热器熔化热熔纤维网。 由于纤维状热熔性粘合剂元件在每一匝被切割并分离成岛状件，所以它们在垫件的外表面和盖件的内表面中像雾滴一样分布。 此后，将垫构件和盖构件叠合并加压使得它们彼此接合。
