ABSTRACT:
A hollow bead of high quality is applied and molded into a shape corresponding to and following a shape of an applying position onto which the bead is to be applied. A bead-molding apparatus includes a discharging device of a double nozzle structure comprised of an inner nozzle and an outer nozzle, a highly viscous material feed unit for feeding a highly viscous material that is fluid in a form of a stream in a high speed flow region and can retain a shape into which it is applied and molded in a low speed flow region, a manipulator disposed so as to transfer the discharging device mounted thereon to a desired position, and a controller for controlling overall operations of the apparatus. The discharging device is controlled so as to move along the applying position of a member while feeding gases thereto from the inner nozzle and discharging the highly viscous material thereto from the outer nozzle.
