According to the present invention, after the heat-reactive adhesive liquid is printed and dried in a predetermined printing pattern on the inner surface of the lining, an arbitrary mesh member and / or the outer surface, and the aforementioned lining, the arbitrary mesh member and the outer surface are combined. A down product in which a pattern joining line for compartment separation is formed by high-frequency heating under pressure with the same pressure-bonding pattern as the above-mentioned printing pattern, and bonding the backing, any mesh member and the outer surface with an adhesive liquid Can be manufactured without forming a sewing hole and without damaging the base plate. According to the present invention, a high-frequency joining method using a heat-reactive adhesive and / or a pre-joining and cutting method in which a double blank is manufactured by first forming a compartment dividing line and then cutting this is used. To produce a down product having an internal bonding line excellent in adhesive strength and durability, and a bonding pattern line in which a clear, excellent finishing quality and aesthetically superior surface pattern line is integrated. As well as being able to mass produce down products by mechanization and automation. |
